| Starting with 1.47, changes marked with SYSLINUX, PXELINUX, ISOLINUX |
| or EXTLINUX apply to that specific program only; other changes apply |
| to all derivatives. |
| |
| Changes in 6.03: |
| * chain: Fix chainloading on 6.02 (Raphael S. Carvalho). |
| * core: Do not leak the __lowmem and __bss16 macros to modules; |
| hide them so modules will not use them. |
| * load_linux: Do not use size heuristic for non-relocatable |
| kernels, for zImage kernels and for non-Linux kernels. |
| * PXELINUX: Fix the SENDCOOKIES feature for HTTP |
| (Russel Santillanes). |
| * gnu-efi: Add gnu-efi as a submodule. |
| * ANSI: Support color tables with more than 256 entries |
| (James Buren). |
| * EFI: Fix displayed version; add DATE (Gene Cumm) |
| * PXELINUX, EFI: Fix bad read of file size over TFTP on EFI64 |
| (Sylvain Gault). |
| * Fix hand over to kernel: |
| "Booting kernel failed: Invalid argument" error. |
| * ISOLINUX: EDX, LBA values higher than 65535; work around for |
| buggy BIOS, where the system would hang, would reboot, or |
| would show a "Disk error 01, AX=42" message. |
| * core/legacynet: Enable dot quad resolution (Gene Cumm). |
| * diag/geodsp improvements (Gene Cumm). |
| * DOS: Fix syslinux.com DOS-based installer. |
| * Improve gcc 4.3.0 compatibility. |
| * syslxint: fix compilation on non-x86 architectures. |
| * localboot: Fix "localboot 0x80" and similar cases. |
| * Add memset() calls prior to any intcall() and other mem fixes; |
| specially relevant for older hardware and/or buggy BIOS. |
| * poweroff.c32: Fixes (Gene Cumm). |
| * HDT: Fix memory leak in CLI (Felipe Pena). |
| * ACPI: Remove memset of buffer; it makes things clearer but |
| also prevents some compilation warnings (Erwan Velu). |
| * Add manpages for isohybrid, memdiskfind |
| (Peter Jones, Gene Cumm). |
| * ISOLINUX: Experimental Rock Ridge support (Thomas Schmitt). |
| * comapi: Remove the comapi interfaces. |
| * EFI: Fixes on PE files and OVMF compatibility |
| (Sylvain Gault, Gene Cumm). |
| * EFI: Updates and fixes for gnu-efi sub-module |
| (Sylvain Gault, Gene Cumm). |
| * BIOS: Fix low memory check. |
| * Filesystem UUID to SYSAPPEND bit 0x40000 for FAT and ext2 |
| (Serj Kalichev). |
| * Makefiles: Export the firmware type as a cpp variable. |
| Additional improvements. Fix "make spotless". |
| * core, BIOS: Move __syslinux_shuffler_size to assembly. |
| Actually get the shuffler size sanely. Fix booting recent |
| Syslinux versions on certain hardware and on certain |
| virtualization software (e.g. QEMU 0.11.1, VirtualBox 4.1.x). |
| * lua: Upgrade to v.5.2.3 (Ferenc Wágner) and additional fixes. |
| * chainload: Fixes to chain.c32 and pxechn.c32. |
| * NTFS: Make byte_shift a constant. |
| * NTFS: Correct parsing of file runs (Andy Alex). |
| * core, BIOS: Correct detection of EDD (Andy Alex). |
| * core: Avoid initializing the cache more than once |
| (Raphael S. Carvalho). |
| * NTFS: Handle fragmented $MFT file (Andy Alex). |
| * BIOS: Use int 0x16, ah=0x02 to probe for shift flags. Attempt |
| workaround for USB keyboards not responding at boot time. |
| * kbd: Getting the keyboard shift state is now a firmware method. |
| * kbd: Fix force-prompt features. |
| * BTRFS: Fix booting on BTRFS. |
| * cache, btrfs: Provide a general cached read routine. |
| * NTFS: Correct file->offset usage in ntfs_readdir (Andy Alex). |
| * New support for UFS/FFS (UFS1/2) (Raphael S. Carvalho). |
| * adv: Remove double definition; |
| it should fix uses of the ADV, including "--once". |
| * memdump: Remove old obsolete COM16 binary. |
| * isohybrid: Numerous fixes (Thomas Schmitt). |
| * chain.c32: Add an adjustable "strict={0,1,2}" flag, improve |
| error reporting (Michal Soltys.) |
| * lpxelinux.0: Workaround for various buggy BIOSes (Gene |
| Cumm.) |
| * PXE: Fix a stack-smashing bug which broke a large number of |
| systems. |
| |
| Changes in 6.02: |
| * efi64: Add support for booting 32-bit kernels. |
| * efi: Use the EFI handover protocol when booting kernels if |
| available. |
| * Fix various make targets that became broken when switching to |
| per-firmware object directories, including 'make install' and |
| 'make netinstall'. |
| * efi: Improve handling of packet loss in UDP stack. |
| * tests: Introduce a new regression test framework designed to |
| ensure bugs are not reintroduced once fixed. |
| * efi: Implement localboot support. |
| |
| Changes in 6.01: |
| * efi: Mark some symbols as __export otherwise libcom32.c32 and |
| vesamenu.c32 will refuse to load. |
| * bios: Wire up the bios kernel loader. It was impossible to |
| load a kernel from bios in 6.00. |
| * efi: Fix 'make installer'. There are no EFI installers so |
| don't try and build them as we run into build errors. |
| * efi: Reuse the initial TFTP client port in subsequent |
| transfers otherwise the server will send an error packet. |
| * efi: Some firmware will not set a default TTL value in IP |
| packets - we must explicitly set it ourselves otherwise a |
| value of zero may be used. |
| * bios, font: Fix a font regression affecting some VirtualBox |
| users. |
| |
| Changes in 6.00: |
| * Add support for booting from EFI. |
| * EFI TCP/IP support. This allows the EFI backend to hook into |
| the generic TFTP, HTTP and FTP functionality. |
| |
| Changes in 5.11: |
| * Dynamic debug support: Add new module, debug.c32, that allows |
| debug code to be dynamically enabled and disabled at runtime. |
| |
| Changes in 5.10: |
| * PXELINUX: An entirely new network implementation based on |
| the lwIP embedded TCP/IP stack. As a result, plain PXELINUX |
| can now support HTTP and FTP without gPXE/iPXE. ls/readdir |
| functionality is supported over HTTP with an indexing |
| webserver, or over FTP with most common FTP servers. For the |
| new network stack use lpxelinux.0. For the legacy stack use |
| pxelinux.0. |
| * Rename the "ipappend" option to "sysappend" ("ipappend" is |
| still accepted as an alias) and make it available for all |
| derivatives. Add additional strings derived from the system |
| DMI/SMBIOS information if available. |
| * "sysappend" strings are also sent as http cookies, with the |
| prefix _Syslinux_ added, on all http transfers. This can be |
| overridden with the SENDCOOKIES configuration file command. |
| * poweroff.c32: A new module to power off a system via APM. It |
| replaces the poweroff COMBOOT module (Sebastian Herbszt). |
| * PXELINUX: Fix booting with DHCP options 209 and 210 which was |
| broken in 5.00. |
| * Handle loading kernel images with no protected mode code. A |
| legitimate kernel image can consist solely of real-mode code. |
| The support for booting such images was broken in 5.00 (Josh Triplett). |
| * Fix a regression in the .psf font file loader introduced |
| in 5.00. |
| |
| Changes in 5.01: |
| * txt/: A new AsciiDoc documentation set (work-in-progress) |
| (Gene Cumm). |
| * core: Fix a bug in the realloc() implementation that caused |
| machines to appear to run out of free memory. |
| * ldlinux: Fix multiple buffer overflows in cmdline parsing |
| code that resulted in files failing to run and cmdlines |
| being truncated. |
| * core: Fix debug build by tagging __bad_SEG() with __export. |
| * com32: Restrict library filenames to 8.3 format. |
| * EXTLINUX: Fix installation and subdirectory patching. |
| * ISOLINUX: Fix booting isohybrid images that are over 32K. |
| * com32: Strip modules to reduce their size. |
| * XFS: Implement directory block cache and fix |
| shortform-directory lookup (Paulo Alcantara). |
| |
| Changes in 5.00: |
| * com32: Switched from the COM32 object format to ELF as it is |
| a much more powerful format that allows undefined symbols to |
| be resolved at runtime and dynamic loading of module |
| dependencies, which means modules now become shared object |
| files instead of statically linked binaries - reducing both |
| disk space and runtime memory consumption. |
| * core: Split non-core functionality into ldlinux.c32, which |
| is an ELF module loaded by the core that contains everything |
| the core doesn't require to boot the system, e.g. config |
| parser, command-line interface, etc. |
| * Replaced __intcall() calls with direct function calls now |
| that we can resolve undefined symbols at runtime, thanks to |
| the ELF object support. Now that we no longer need to go |
| through the 16-bit interrupt mechanism we can make full use |
| of the 32-bit execution environment. This change required |
| reimplementing lots of the 16-bit assembly code from core/ |
| in C. |
| * com32: __com32.cs_bounce is gone now we always run in a |
| 32-bit environment once we execute ldlinux.c32. |
| * ldlinux: A new "PATH" directive was added to the ldlinux.c32 |
| config parser that specifies a colon-separated list of |
| directories to search when attempting to load modules. |
| * ALL: Delete all references to/code for 16-bit COMBOOT files. |
| COMBOOT files (.cbt and .com) are no longer supported under |
| Syslinux. |
| |
| Changes in 4.07: |
| * EXTLINUX: fix crash caused by dereferencing garbage pointer. |
| * Plug memory leak in searchdir which eventually leads to an |
| observable hang (Shao Miller). |
| * ISOLINUX: fix bug triggered by isohybrid images larger than |
| 32K which results in an invalid image checksum error. |
| * menugen: make it Py3k compatible (Paulo Alcantara). |
| |
| Changes in 4.06: |
| * Support for NTFS, by Paulo Alcantara. |
| * EXTLINUX: more robust device detection, allow user to override. |
| * kontron_wdt.c32: Add a new module to enable the hardware |
| watchdog of some Kontron boards. It allows enabling the watchdog |
| and then booting a given image. |
| * HDT updated, and now can display images regarding some detection |
| steps. Add postexec command to run a particular entry after |
| HDT's execution, add silent option and various fixes. |
| * ifcpu.c32: Detect hypervisor presence. |
| * lua.c32: Add dhcp support and support for native Syslinux |
| functions syslinux_config(), syslinux_ipappend_strings() and |
| syslinux_reboot(). |
| * isohybrid: Workaround for various EFI systems. |
| * pxechn.c32, a PXE NBP chainloader. More versatile alternative |
| to pxechain.com and resolves the PXELINUX -> WDS issue with |
| Microsoft Windows Server 2008R2 (Gene Cumm). |
| * btrfs: Fix booting off of a subvolume. |
| * com32: Add device tree support. |
| * SYSLINUX: Fix relative paths for VFAT. The CONFIG and APPEND |
| directives now support entirely relative paths. |
| |
| Changes in 4.05: |
| * HDT updated, and now supports uploading data to a TFTP |
| server. |
| * ISOLINUX: remove the .img file support; it has been broken |
| on virtually all systems since the beginning, and has been |
| totally broken since 4.00 at least. Use MEMDISK instead. |
| * chain.c32: Support chaining ReactOS' FreeLdr (Shao Miller) |
| * isohybrid: -m option to add support for Mac EFI booting. |
| * ifmemdsk.c32: Choose boot option based on presence of |
| MEMDISK. |
| * Remove bogus distributed mk-lba-img binary. |
| * The Syslinux project has a new, cool logo by Abi |
| "ixxvil" Rasheed (doc/logo/*). |
| |
| Changes in 4.04: |
| * PXELINUX: Fix handling of unqualified DNS names. |
| * PXELINUX: Fix timer bug when PXELINUX might be unloaded |
| (Gene Cumm). |
| * core/writedec.inc: Fix duplicate declaration and overflow |
| (Gene Cumm). |
| * GCC 4.5 fixes. |
| * sample directory: Fix Makefile include (Gene Cumm). |
| * ver.com: New universal DOS/COMBOOT application to display |
| version information (includes DRMK) (Gene Cumm). |
| * rosh.c32: updated; Using getopt() for internal commands to aid |
| parsing options; Fix bugs in ls; add warm reboot and echo |
| (Gene Cumm). |
| * com32: fix a file descriptor leak. |
| * gfxboot.c32: handle TEXT..ENDTEXT; error out on no LABELs |
| found (Sebastian Herbszt). |
| * Fix booting on non-partitioned devices. |
| * MBR, isohybrid: Workaround for a BIOS issue on Acer |
| Travelmate and possibly other machines. |
| * COM32: Adding ACPI parsing libary |
| * HDT: Release 0.4.1 to support ACPI parsing, |
| improved mutli-core/cpu reporting |
| * LUA: Updating to 5.1.4-2 |
| * SYSLINUX: core/diskstart.inc: Reset DS after checksum in case |
| it isn't 0 (Gene Cumm). |
| * win64: Script update for additional mingw compiler names |
| (Gene Cumm). |
| * diag: New directory for diagnostic-related tools. Add a |
| handoff MBR/VBR and geometry display images (Gene Cumm). |
| * MEMDISK: use "mem=" parameter to mark available memory above |
| this point as reserved (core already does alignment) (Gene Cumm). |
| * MEMDISK: Additional disk probe checks and debug output |
| (Shao Miller, Gene Cumm). |
| * gpxe: add gpxelinuxk.0, based off of undionly.kpxe + new |
| script (Gene Cumm). |
| * isohybrid: install the isohdpfx*.bin/isohdppx*.bin files to |
| make isohybrid images in one step with GNU xorriso. |
| * PXELINUX: disable a hack that would make localboot work on |
| some machines, but break just about as many. Some machines |
| which worked with "localboot 0" in previous versions may |
| need "localboot -1" in this one. If you have a machine |
| which requires "localboot -1", a copy of the dmidecode |
| or sysdump output would be appreciated. |
| * Include a set of diagnostics by Gene Cumm. |
| * Fixes for gcc 4.6 and binutils 2.21.51. |
| * chain.c32: Allow "uuid" as a synonym to "guid". |
| * Handle directory names starting with .. for vfat and |
| iso9660. |
| * New MENU HIDDENKEY command to provide a one-keystroke way to |
| activate a boot option from a hidden menu intro screen. |
| |
| Changes in 4.03: |
| * Don't hang if no configuration file is found. |
| * Better support for booting from MBRs which don't pass |
| handover information. |
| * EXTLINUX: Try to be smarter about finding the partition |
| offset. |
| * chain.c32: support chainloading Dell Real Mode Kernel (Gene |
| Cumm). |
| * chain.c32: fix booting in CHS mode. |
| * rosh.c32 updated (Gene Cumm). |
| * Fix the -s option to the syslinux/extlinux installer (Arwin |
| Vosselman). |
| * isohybrid: fix padding of large images (PJ Pandit). |
| |
| Changes in 4.02: |
| * SYSLINUX: correctly handle the case where the -d option is |
| specified with a non-absolute path, i.e. "syslinux -d |
| syslinux" instead of "syslinux -d /syslinux". |
| * ISOLINUX: recognize the directory names /boot/syslinux and |
| /syslinux, and the filename syslinux.cfg in addition to the |
| isolinux-specific names. Thus, "syslinux.cfg" is now a |
| generic name, whereas "isolinux.cfg" or "extlinux.conf" is |
| specific to different derivative. |
| * chain.c32: support setting alternate config filename for |
| stage2 of GRUB Legacy (Gert Hulselmans). |
| * whichsys.c32: execute specific command, based on Syslinux |
| bootloader variant (Gert Hulselmans). |
| * lua.c32: a lot of new bindings added to the "syslinux" |
| namespace: VESA, PCI, DMI, kernel loading (Marcel Ritter). |
| * btrfs: print a comprehensive error message if compressed or |
| encrypted files are encountered (neither is currently |
| supported.) |
| * SYSLINUX: mtools installer: honor TMPDIR, error out on disk |
| full. |
| * Handle fallbacks from EDD to CHS, to deal with systems which |
| announce EDD support but don't actually have it. |
| * SYSLINUX: the mtools, DOS and win32 installers now use the new |
| command line options. |
| * PXELINUX: fix the use of IP addresses in TFTP :: or tftp:// |
| host syntax. |
| * SYSLINUX: experimental Win64 installer (syslinux64.exe). |
| |
| Changes in 4.01: |
| * ISOLINUX: fix initialization on systems which don't zero |
| low memory. |
| * SYSLINUX/EXTLINUX: fix handing of disk read retries in |
| EDD mode. |
| * ISOLINUX: change the initialization sequence to avoid |
| problems with certain (old) BIOSes. Special thanks to |
| Helmut Hullen for invaluable debugging support. |
| * ifplop.c32: new module which detects if the PLoP Boot Loader |
| already has booted a CDROM or USB drive (Gert Hulselmans). |
| * Correct a severe memory overwrite bug, triggered primarily |
| when selecting a very long command line in the menu system. |
| * lua.c32: Lua script interpreter, currently experimental |
| (Alexey Zaytsev, Marcel Ritter, Geert Stappers). |
| * PXELINUX: new option IPAPPEND 4 to append the system UUID to |
| the kernel command line. |
| * PXELINUX: display BOOTIF and SYSUUID at startup time, and |
| when Ctrl-N is pressed on the command line. |
| |
| Changes in 4.00: |
| * Major code base changes; all filesystem rewritten in C. |
| This work was done primarily by Liu Aleaxander (Yuanhan Liu). |
| * EXTLINUX: btrfs and ext4 support. btrfs support was done by |
| Alek Du of Intel. |
| * EXTLINUX is no longer a separate derivative; extlinux and |
| syslinux both install the same loader (ldlinux.sys); for the |
| Linux-based installers the extlinux binary is used for a |
| mounted filesystem; the syslinux binary for an unmounted |
| filesystem. |
| * When loading a new configuration file with the CONFIG |
| command, one can now also specify a new current directory |
| with an APPEND statement. |
| * Full ADV support for Syslinux, to boot-once and MENU SAVE |
| works. |
| * Full support of GPT-partitioned disks, including disks |
| and/or parititions larger than 2 TiB (if supported by BIOS.) |
| * The GPT handover protocol adjusted to the current T13 |
| committee draft; see doc/gpt.txt. |
| * HDT: code cleanup, small bugfixes |
| * The "linux" syslinux installer (syslinux-nomtools) now has a |
| command-line syntax closer to the extlinux installer. The |
| mtools, dos and win32 installers will get this new syntax |
| eventually, but it is not implemented yet. |
| * chain.c32: support booting GPT partitions by index, GUID, label. |
| * chain.c32: support booting the Syslinux partition with "fs". |
| * chain.c32: implement gpt.txt hand-over protocol. |
| * chain.c32: support for chainloading Grub stage 2. |
| * PXELINUX: TFTP URL syntax (tftp://) supported even when not |
| running gPXE/gpxelinux. |
| * New ls.c32 module to display the contents of the disk from |
| the command line, and pwd.c32 to display the current |
| directory. |
| * rosh.c32 (read only shell) updated and hopefully usable. |
| * PXELINUX: Support "localboot -1", just like the other |
| derivatives. |
| * gfxboot.com removed in favor of gfxboot.c32. |
| * New MENU HELP statement to display fullscreen help text as a |
| result of a menu selection. |
| * memdiskfind utility that can be used with the phram driver |
| in the Linux kernel to mount a memdisk. |
| * ifcpu.c32: Adding usage when no parameters are given, |
| adding PAE support. |
| * ifcpu.c32, ifcpu64.c32: handle more than one argument per |
| target. |
| * isohybrid: C version which does not require Perl. |
| * New command MENU IMMEDIATE to permit hotkeys to activate |
| immediately without needing Enter. |
| * mdiskchk.com supports a --no-sequential (or -n) option to |
| suppress the classic all-drive-probing heuristic. Useful |
| on BIOSes who crash/hang when certain drive numbers are |
| probed. |
| * ElTorito.Sys DOS driver now scans drive numbers upwards |
| instead of downwards, in order to avoid a fairly common |
| bug on some BIOSes where probing drive 0xFF causes a |
| failure. |
| * NASM 2.03 or later required to build. 2.07 or later |
| recommended. |
| |
| Changes in 3.86: |
| * chain.c32: fix chainloading the MBR of a hard disk (broken |
| in 3.85). |
| * mboot.c32: report the boot loader name in the information |
| structure. |
| * com32: set argv[0] in a com32 module. |
| * core: add a workaround for a bug in Xen HVM older than |
| version 3.3: disable halt on those platforms. |
| * Fix problems where certain operations in com32 modules would |
| cause the core to believe the system was idle. |
| * MEMDISK: fix MBR detection when used with a DOSEMU header or |
| an offset. |
| * MEMDISK: generate the mBFT checksum correctly. |
| |
| Changes in 3.85: |
| * gPXELINUX: updated to gPXE 1.0.0. gPXELINUX can now do NBP |
| chainloading, and does not require a second DHCP. |
| * vesamenu.c32: unbreak the default "grey hole" background. |
| * We no longer have a built-in default of "linux auto". |
| Instead, if no DEFAULT or UI statement is found, or the |
| configuration file is missing entirely, we drop to the boot: |
| prompt with an error message (if NOESCAPE is set, we stop |
| with a "boot failed" message; this is also the case for |
| PXELINUX if the configuration file is not found.) |
| * chain.c32: support chainloading Grub4DOS; patch by Gert |
| Hulselmans. |
| * New tool: sysdump.c32, can be used to produce system |
| information for debugging via tftp or ymodem (serial port). |
| * "vga=current" on the Linux command line is now supported. |
| * chain.c32: support for Windows Recovery Console, via the |
| "cmldr=" option. |
| * chain.c32: should now support loading NTLDR from different |
| type media than loaded from. |
| * chain.c32: support chainloading to a FAT/NTFS partition with |
| invalid "hidden sectors" via the "sethidden" option. |
| * memdisk: fix the mBFT ACPI table. |
| * vesamenu.c32: if the image is smaller than the screen, tile |
| it across the whole screen. |
| * mkdiskimage: -s option for producing a sparse image. |
| * vesamenu.c32: support arbitrary resolution setting (beyond |
| BIOS support) on some Intel-based video chipsets. This code |
| is a modified version of the "915resolution" tool by |
| Steve Tomljenovic; your mileage might vary. |
| |
| Changes in 3.84: |
| * SYSLINUX: make the DOS installer work for MS-DOS 7.x/8.x |
| (Win9x/ME) again. |
| * HDT: updated to version 0.3.6 (numerous changes.) |
| * mboot.c32: now supports video mode setting if requested by |
| the image. |
| * MEMDISK: Fix floppy images of PC-DOS. |
| * MEMDISK: Add support for emulation of CD-ROM images; patch |
| by Shao Miller. |
| * MEMDISK: Comply with the Win9x "safe hook" standard, |
| allowing a protected-mode driver. |
| * MEMDISK: New "mBFT" ACPI table, by analogy with the iSCSI |
| iBFT table. This allows detection from a protected-mode |
| operating system without EDD support. |
| * 32-bit version of the gfxboot loader (gfxboot.c32), so far |
| experimental. This will replace gfxboot.com in the future. |
| * vesamenu.c32: new MENU RESOLUTION directive to set a screen |
| resolution other than 640x480. |
| * chain.c32: add support for loading isolinux.bin. |
| * chain.c32: make sure to always return to text mode. |
| * eltorito.sys: DOS driver for generic CD-ROMs; by Gary Tong |
| and Bart Lagerweij. |
| |
| Changes in 3.83: |
| * PXELINUX: clear memory before handing over to a chainloaded |
| NBP. This may help avoid a bug in Windows RIS. |
| * PXELINUX: fix localboot after NBP chainloading on certain |
| BIOSes (including ASUS A8N-E, but possibly others.) |
| * chain.c32: support chainloaded bootloaders on ISOLINUX. |
| * PXELINUX: allow filenames up to 251 characters. |
| * MEMDISK: fix problems booting from USB on Thinkpads, and |
| possibly other machines or hardware combinations. |
| * isohybrid: fix the -id option. |
| * HDT: updated to version 0.3.4. |
| * MEMDISK: the stack size is now configurable, with the stack= |
| option. |
| * Simple menu: fix Ctrl-W (word erase) in command-line edit. |
| * Simple menu: fix crash on some platforms. |
| * Gfxboot: fixes to the configuration file parsing. |
| * PXELINUX: add a tool to override specific DHCP options via |
| values hardcoded in the pxelinux.0 file. These hardcoded |
| values can be either "before DHCP" (defaults if DHCP do not |
| provide values), or "after DHCP" (overrides DHCP). The tool |
| pxelinux-options can be used to set these options. This |
| feature does not apply to gpxelinux.0; when used with gPXE |
| this is better handled by modifying the embedded script. |
| |
| Changes in 3.82: |
| * isohybrid: fix the -partok logic for loading from a partition. |
| * ISOLINUX: deal with systems which return from INT 13h with |
| interrupts disabled. |
| * Do not invoke the idle handler during large file loads. |
| * Simple menu: make ONTIMEOUT work with MENU HIDDEN. |
| * PXELINUX: handle TFTP servers which have extra NULs at the |
| end of an OACK packet. |
| |
| Changes in 3.81: |
| * Shuffler: fix bug in real-mode entry. This affected a |
| number of modules, probably in relatively unimportant ways, |
| but it completely broke linux.c32. |
| * Improved performance. |
| * Attempt to halt the processor while idle. This can cause |
| bad reponsiveness when using a serial console especially for |
| automated input; if that ends up being a problem, use the |
| new "NOHALT 1" configuration command. |
| * linux.c32 now suppresses all messages if the "quiet" flag is |
| specified. |
| * isohybrid: add a variety of options, and a help message. |
| * ISOLINUX: fix booting in hybrid mode when CBIOS is used. |
| This unfortunately means that the isohybrid handoff protocol |
| has changed, so the isohybrid utility must version-match |
| isolinux.bin. |
| * Drop support for ACPI 3 extended memory flags. |
| * Menu system: don't set the autocr flag on the serial |
| console. |
| * altmbr: fix handling of logical partitions. |
| * altmbr: cap at 439 bytes so the partition select byte isn't |
| part of the file. |
| |
| Changes in 3.80: |
| * New shuffler mechanism and API. |
| * Rewritten mboot.c32 module. |
| * The syslinux_boot_linux() function has been simplified. |
| * Don't hang trying to boot a "menu quit" label from the CLI. |
| * Fix problem with boot-once "sticking" on some BIOSes. |
| * isohybrid: fix problem with images over 2 GB in size. |
| * APM poweroff module (poweroff.com) by Sebastian Herbszt. |
| * ISOLINUX: fix the handling of large directories. Bug found |
| and fixed by Steffen Winterfeldt. |
| |
| Changes in 3.75: |
| * PXELINUX: fix the "keeppxe" option, which was broken in |
| 3.74. |
| * MEMDISK: correct the extraction of geometry information from |
| the MBR of a hard disk image, again broken in 3.74. |
| * extlinux(1) man page from Brian Pellin. |
| * Simple menu: MENU SAVE is now controllable on a menu-by-menu |
| or entry-by-entry basis. |
| * gPXELINUX: fix interrupt-disabling bug. |
| * HDT: fix lockup on machines with certain PCI configurations. |
| |
| Changes in 3.74: |
| * New UI directive, which allows a more natural way to specify |
| a menu system (or not.) With the UI directive specifying |
| the menu system, the DEFAULT directive can be used to select |
| the default entry inside the menus. |
| * kbdmap.c32: new module to load a new keyboard map |
| dynamically. |
| * isohybrid: workaround bug in some versions of binutils. |
| * Fix issue with the placement of the initrd on some machines. |
| * ifcpu64: fix handling of less than three arguments. |
| * Fix bug in the shuffle library when dealing with a very |
| large number of fragments. |
| * Documentation fixes by Vicente Jimenez Aguilar. |
| * gPXE updated to version 0.9.7. |
| * hdt.c32: Hardware Detection Tool, an interactive hardware |
| analyzer module by Erwan Velu. |
| * MEMDISK: enable automatic determination of the disk geometry |
| for a large floppy disk image if (and only if) it is |
| formatted with a FAT filesystem. |
| * SYSLINUX: fix the handling of .bss files on FAT12/16. |
| * Suppress the Loading ... message if "quiet" is specified on |
| the kernel command line. |
| * Fix the use of "CONSOLE 0" with menu.c32. |
| * Allow COM32 modules to be aware of all memory even in the |
| presence of a memory hole. The "linux.c32" module can be |
| used to load a kernel (or memdisk) plus large initrd on |
| such a system. |
| * MBR: produce alternate MBR variants which force the drive |
| number to hd0 (_f variants), or force the drive number to |
| hd0 if the Ctrl key is pressed (_c variants.) Furthermore, |
| add an MBR variant (altmbr*.bin) which ignores the active |
| flag and instead boots the partition number specified in the |
| byte at offset 439 decimal. |
| * Add IPAPPEND strings to com32 modules, especially needed for |
| linux.c32. |
| * New MENU SAVE directive which saves the latest menu |
| selection until the next boot. Currently only implemented for |
| EXTLINUX. |
| * gfxboot.com: *experimental* interface module to Steffen |
| Winterfeldt's "gfxboot" graphical front end |
| (http://gfxboot.sourceforge.net/). Module by Sebastian Herbszt. |
| |
| Changes in 3.73: |
| * Upgrade gPXE to release version 0.9.5. |
| * Fix a number of build errors on various platforms. |
| * Handle systems with E820 "extended attributes" per ACPI 3. |
| Someone "cleverly" decided to change the E820 spec in a |
| backwards-incompatible manner! |
| * MEMDISK: default to "safeint". |
| * Adopt the moniker "The Syslinux Project", standard proper |
| noun capitalization, to refer to the project as a whole. |
| Thus, reserve the all-caps "SYSLINUX" to refer to the FAT |
| loader. |
| * mboot.c32: add "-solaris" option to pass DHCP information to |
| the Solaris kernel; required for automatic Solaris boot |
| without using Solaris' pxeboot program. |
| * config.c32: trivial COM32 module to restart Syslinux with |
| another configuration file from the command line (equivalent |
| to the CONFIG command in the configuratin file.) |
| |
| Changes in 3.72: |
| * Include the pxechain.com module from Jeffery Hutzelman at |
| Carnegie Mellon University. This allows chaining another |
| PXE boot program while changing the DHCP packet passed to |
| it. |
| * Reorganize the Makefile system. |
| * Major PCI core cleanups and other source cleanup. |
| * gPXE code updated. |
| * Try to avoid memory-snooping attacks on passwords. Note |
| that if someone has root on the box, they generally don't |
| need to compromise the boot loader... |
| * ISOLINUX: fix crash when given a zero-length file. |
| * sdi.c32: support gzipped SDI images. |
| * ISOLINUX: support generating images which can be either |
| a CD-ROM or a hard disk (USB disk, etc.) See |
| doc/isolinux.txt for more information. |
| * Remote gdb support for COM32 modules; patch from Stefan |
| Hajnoczi. |
| * Support beeps in F-key help in the simple menu system. |
| * Tab display of labels, based on a patch from Sebastian |
| Herbszt. Can be disabled with the NOCOMPLETE configuration |
| command. |
| * "menu default" can now be specified after "menu begin", to |
| indicate that a specific submenu should be the default entry. |
| |
| Changes in 3.71: |
| * Workaround for a VESA BIOS which tries to make DOS system |
| calls(!!) |
| * Simple menu: fix navigation around disabled entries |
| (or at least try to...) |
| * EXTLINUX: proper error message when confused about mount |
| point. |
| * MEMDISK: be smarter about incompletely disabled floppies in |
| the BIOS and about being the only floppy. |
| * Optionally allow initrd to be specified on a separate line |
| rather than as part of the "append" line. This is not |
| recommended, but apparently makes life easier for some |
| tools. |
| * SYSLINUX: if no config file is present, set the current |
| directory to the root directory (Sebastian Herbszt). |
| * chain.c32: option "hide" to support hiding and unhiding of |
| primary partitions on the boot drive with DOS, Win, or OS/2 |
| partition types (01, 04, 06, 07, 0b, 0c, 0e). |
| * Unbreak the KBDMAP command (broken in 3.70). |
| * EXTLINUX: fix the handling of the ADV when using CBIOS. |
| * ifcpu64.c32: simple COM32 module to select a 32- or 64-bit |
| kernel (and optionally 32-bit kernels with or without PAE.) |
| Eventually we want a scripting language for this |
| kind of stuff; a Lua module is under development. |
| * Fix parsing of the SERIAL command without a baud rate |
| specified. |
| * chain.c32: error out when try to boot an unbootable |
| partition. |
| * SYSLINUX: when building the Win32 installer, search for |
| MinGW under a large number of possible names. |
| |
| Changes in 3.70: |
| * PXELINUX: Support enhanced capabilities when running on top |
| of gPXE (http://www.etherboot.org/). In particular, support |
| URL-style syntax for filenames, and any protocol that gPXE |
| supports (except, currently, iSCSI and AoE.) This feature |
| is currently highly experimental. |
| * Substantial infrastructure changes to support files whose |
| length aren't known at open time (typically network |
| connections.) Please note that the semantics of some of the |
| comboot APIs have changed slightly; please see doc/comboot.txt. |
| * PXELINUX: We no longer require a TFTP server which supports |
| the tsize option for all transfers. |
| * PXELINUX: Integrate with the gPXE source base; unified image |
| now included as "gpxelinux.0". |
| * The source tree has been restructured; files that were |
| previously in the root have moved into the core, dos, gpxe, |
| and utils directories. |
| * "make install", "make netinstall", and "make extbootinstall" |
| have been updated massively. "make install-all" now installs |
| all three. |
| * Change default dir for auxiliary files from |
| /usr/lib/syslinux to /usr/share/syslinux. |
| * SYSLINUX: VFAT long filename support. |
| * MEMDISK: Any image less than 4096K (4 MB) is treated as a |
| floppy disk. The geometry-guessing code will recognize all |
| common extended formats, but it is still possible some very |
| exotic formats need geometry specification. Large floppies |
| and very small harddisks still need explicit specification. |
| * chain.c32: option "swap" to support swapping of BIOS drive |
| numbers. This is necessary to boot certain operating systems |
| (DOS, Windows) from a secondary drive. |
| * chain.c32: option "file=" to support loading a boot file from |
| the SYSLINUX filesystem instead of loading the boot sector |
| from the drive. |
| * chain.c32: option "seg=" to control the load location. |
| * chain.c32: option "ntldr=" as a shorthand for "seg=0x2000 |
| file="; use this to load one of WinNT's loaders: |
| |
| chain.c32 hd0 1 ntldr=/MiniNT/setupldr.bin |
| |
| Note that the file needs to be in the SYSLINUX filesystem. |
| * chain.32: options "freedos=" and "msdos="/"pcdos=" as |
| shorthands for "seg=0x60 file=" and "seg=0x70 file=" |
| respectively; use this to load FreeDOS's kernel.sys, MS-DOS's |
| io.sys or PC-DOS's ibmbio.sys. |
| * Change to the A20 algorithm which *MIGHT* help systems that |
| have systems which freeze when Syslinux is used with USB |
| keyboards. Note that this has been hard do verify, so I |
| would greatly appreciate feedback on it. |
| * Complex menu system: unbreak menus which has unnamed |
| submenus, like complex.c. |
| * Fix newline on the serial port for some com32 modules. |
| * chain.c32: support "boot" as the drive specification, |
| indicating the drive from which it was booted |
| (for syslinux/extlinux). |
| * SYSLINUX/EXTLINUX: support "localboot" with the same feature |
| set as ISOLINUX. |
| * Add an experimental MBR for GPT partition tables. |
| * Use $(CC) when determining compile flags. |
| * chain.c32: fix booting from logical partitions (Sergey |
| Vlasov.) |
| |
| Changes in 3.63: |
| * Fix errors in the PCI and DMI detection modules (Erwan Velu, |
| Sebastian Herbszt). |
| * Fix host dependencies and other issues in the build system. |
| * PXELINUX: Allow class E addresses as unicast. |
| * sdi.c32: module to load Microsoft System Deployment Images. |
| For additional information, please see: |
| http://msdn2.microsoft.com/en-us/library/ms838543.aspx |
| * EXTLINUX: Correct reading directories with deleted entries. |
| * Shuffle library: correct the handling of certain geometries |
| (an upward move with source material blocking the move); as |
| required by sdi.c32 but theoretically possible for other |
| formats as well. |
| * Add "make netinstall" to install /tftpboot. |
| * Fix some documentation files that didn't get moved/renamed. |
| |
| Changes in 3.62: |
| * Clean up garbage after "aborted." message. |
| * Clean up memdump.com filenames. |
| * Support SHA256 and SHA512 encrypted passwords. |
| * The shuffle library now can generate chained descriptors, |
| thus allowing pretty much arbitrarily complex memory maps. |
| * Handle command lines up to 2047 characters, the current |
| Linux kernel limit. |
| * vesamenu: support systems without linear framebuffer support |
| (sigh, what is this, 1993?) and 15-bit RGB modes. |
| * Move the label storage (for the command-line interface) to |
| high memory, removing the size limit and freeing up 64K of |
| low memory. |
| * Get rid of 4096-entry limit in the simple menu system. |
| * New hierarchial submenu support: see MENU BEGIN, MENU END, |
| MENU GOTO in doc/menu.txt. |
| * MENU QUIT allows creating a menu entry for returning to the |
| command line. |
| * ISOLINUX: Work around bug in certain Adaptec BIOSes, |
| patch by Bruce Robson. |
| * pngtopnm dependency removed from samples/ directory. |
| * Text documentation files (in doc/) renamed *.doc -> *.txt. |
| |
| Changes in 3.61: |
| * EXTLINUX: fix crash when accessing an empty file. |
| * elf.c32: If a PHDR segment is present, load it. |
| * Fix SHA-1 and MD5 passwords. |
| * ISOLINUX: fix booting when mastered without |
| mkisofs -boot-info-table (broken since 3.50, sigh...) |
| * Handle BIOSes which emit multiple contiguous valid |
| memory regions in the e820 map. |
| |
| Changes in 3.60: |
| * Support for "auxilliary data vector", a small amount of |
| writable storage. Currently only supported for EXTLINUX, |
| but the infrastructure is there for the other derivatives, |
| assuming a suitable storage location can be found. |
| * EXTLINUX: boot-once support (--once, --clear-once, and |
| --reset-adv). |
| * A command is now required to the EXTLINUX installer, i.e. at |
| least one of --install, --update, --once, --clear-once, or |
| --reset-adv. |
| |
| Changes in 3.55: |
| * PXELINUX: as per RFC 5071, PXELINUX no longer requires the |
| use of the magic cookie option (208) for unencapsulated |
| options. Currently it does not require it for |
| vendor-encapsulated options (vendor-option-space) either, |
| but that MAY be reverted in the future if it causes |
| problems. |
| * Documentation text files moved to a common "doc" directory; |
| man pages from the Debian project added to the "man" |
| directory. |
| * Correct bug with self-overlapping memory areas when using |
| the shuffle interface. |
| |
| Changes in 3.54: |
| * Add "menu separator", "menu indent", "menu disabled" |
| (see README.menu). |
| * vesamenu: fix handing of VESA modes with noncontiguous |
| memory buffers. In particular, Qemu/KVM sets up such a mode |
| when Cirrus Logic emulation is enabled (which is the |
| default.) |
| * Support for calling real mode functions using far calls, |
| with argument on the stack. This was implemented to support |
| the BIOS BBS specification, but subsequent experiments show |
| that the at least one of the most common BIOS cores, Award, |
| passes the presence check but doesn't actually implement the |
| functionality. |
| |
| Changes in 3.53: |
| * Fix bugs related to the $PnP BIOS functionality on some |
| platforms. |
| * PXELINUX: Fix the "naked" version of :: (suppress prefix.) |
| * elf.c32: better error messages. |
| * Faster operation under Intel VT virtualization. |
| * PXELINUX: Fix DHCP bootfile option. |
| * mkdiskimage: Support more than 1024 cylinders. |
| * (Hopefully) fix installer on non-x86 platforms. |
| * Fix shuffle_and_boot_rm, used by linux.c32. |
| * Fix shuffle_and_boot_pm on 386/486. |
| * ISOLINUX (at least): fix bss memory overwrite hang. |
| * MBR: Fix booting from logical partitions. |
| * Code cleanups. |
| |
| Changes in 3.52: |
| * Handle capitalized F-key commands in the menu system. |
| * Fix padding error when loading multiple ramdisks. |
| * Workaround for VMware crashing when trying to print a |
| message during early kernel boot (does not seem to work, |
| consider deleting.) |
| * chain.c32: add the ability to search for a specific MBR |
| signature at runtime. |
| * Fall back to the server identity option if the siaddr field |
| in the DHCP header isn't set. This seems to match the |
| behaviour of most PXE stacks. |
| * mkdiskimage: give the generated disk image an MBR signature. |
| * MEMDISK: Fix failures on some BIOSes. |
| * Simple menu system: new "MENU HIDDEN" option to not display |
| the menu unless the user presses a key. |
| * Simple menu system: support MD5-encrypted passwords (modern |
| Unix standard style, with "$1$" prefixes.) |
| * pcitest.c32: now functions as a full "lspci". Thanks to |
| Erwan Velu for this work. |
| * MEMDISK: Make EDD actually work. |
| * ISOLINUX: Fix for certain broken CD-ROM BIOSes which |
| randomly corrupted register FS. |
| * Simple menu system: fix memory overwrite bug that caused |
| some systems to lock up or behave weirdly. |
| * Fix building on 64-bit systems without a 32-bit libc installed. |
| |
| Changes in 3.51: |
| * EXTLINUX: Fix failure to find the configuration file. |
| |
| Changes in 3.50: |
| * New keywords allow the type of file to be specified in the |
| configuration file. |
| * It is now supported to load a different configuration file |
| with the CONFIG keyword. |
| * Fix API call 0x0019 (Read Disk.) |
| * MENU AUTOBOOT, MENU TABMSG, MENU PASSPROMPT allows |
| internationalization of menu messages. |
| * A new feature, TEXT HELP, allows the administrator to set |
| a multi-line help message for individual selections. |
| * Fix API call 0x0012 (Cleanup, shuffle and boot.) |
| * New API call "Cleanup, shuffle and boot to flat protected mode" |
| * New API call "Cleanup, shuffle and boot to real mode", |
| similar to API call 0x0012 but allows arbitrary register setting. |
| * Introduce a library interface for loading arbitrary binary |
| formats with relatively easily understood code. See |
| the elf.c32 module for an example on how to use it. |
| * New module "elf.c32", to load a protected-mode ELF kernel. |
| * MBR (old and new): Fix bug in CHS mode when LBA > |
| 65535*sectors. |
| * vesamenu: fix decoding of palettized PNG images. |
| * Update the Linux kernel boot protocol. |
| * PXELINUX: Press Ctrl-N at the boot prompt to read out the |
| network info. |
| * Instead of the (non-existent) MAC, use the client identifier |
| for networks like Infiniband and Firewire/1394. |
| * Add a new INCLUDE command to the core syslinux parser. |
| * Allow binding help text to F11 and F12. |
| * F-key help now available in the simple menu system. |
| * Disabled the polling for ARP during idle. It is simply too |
| slow on some (broken!) PXE stacks. |
| * PXELINUX: also try to fetch the config file based on UUID. |
| * SYSLINUX/EXTLINUX: New RAID mode (-r) which calls the BIOS |
| to load the next device (typically the next drive) on boot |
| failure. |
| |
| Changes in 3.36: |
| * MEMDISK: Disable EDD by default on floppy disks. EDD can be |
| enabled with the "edd" option and disabled with "noedd". |
| This (hopefully) should make Ghost work again. |
| * SYSLINUX: "unix" installer now uses Linux ioctls instead of |
| using libfat. |
| * New MBR which can boot from logical partitions. |
| * SYSLINUX: Fix bug in detecting special extensions which was |
| introduced in 3.35 :( |
| * PXELINUX: Unbreak chainbooting FreeBSD (and possibly others.) |
| |
| Changes in 3.35: |
| * MEMDISK: New "safeint" mode. |
| * MEMDISK: Be more compliant with the PnP BIOS spec. |
| * MEMDISK: Turn on EDD support by default. |
| * MEMDISK: Try to work on some machines on which it would not |
| work when there was no floppy drive in the system. |
| * Simple menu system: fix serial console support (broken in |
| 3.30). |
| * SYSLINUX: Support subdirectories. Like ISOLINUX, the |
| "current directory" is the directory in which syslinux.cfg |
| is found; this is searched for in the sequence |
| /boot/syslinux, /syslinux, /. As a side benefit, label names |
| like "linux-2.6.18" and "linux-2.6.19" are now supported. |
| |
| To install ldlinux.sys in a subdirectory, pass the -d |
| directory option to the SYSLINUX installer. |
| |
| This work was sponsored by slax.org (thanks, Tomas!) |
| * New API call: read disk. |
| * Invoke ONERROR on initrd load failure. |
| |
| Changes in 3.31: |
| * The simple menu system (menu.c32 and vesamenu.c32) now |
| support loading more than one configuration file at a time, |
| using MENU INCLUDE or by specifying multiple filenames. |
| * The MENU COLOR statement can now control the shadowing mode. |
| |
| Changes in 3.30: |
| * libcom32 extended to support graphics mode and graphical console. |
| * vesamenu.c32, new graphical version of the Simple |
| Menu System, see README.menu. |
| * New com32 modules by Erwan Velu do selection based on CPUID |
| or PCI devices present. |
| * RPM spec: add syslinux-tftpboot module; move syslinux by |
| default to the /usr/share/syslinux directory. |
| * RPM spec: extlinux is now a separate package. |
| |
| Changes in 3.20: |
| * EXTLINUX: New options --install (-i) and --update (-U), to |
| make it clear if a boot loader should be installed or |
| updated. For now, defaults to --install for compatibility; |
| a future version will require one of these options. |
| * New library functions to load and place files in memory. |
| * mboot.c32 bug fixes. |
| * Remove 8 MB kernel size restriction. |
| * Add "klibc" target for building unix/syslinux and |
| extlinux/extlinux with klcc (klibc-1.4.27 or later.) |
| * PXELINUX: Fail (and eventually reboot) if no configuration |
| file was found. |
| * COM32 module by Erwan Velu to make decisions based on DMI |
| info. |
| * Fix issue where going back and forth between menus a lot |
| would cause a hang. |
| * ISOLINUX: Fix bug which made "cd boot sectors" not work. |
| |
| Changes in 3.11: |
| * MEMDISK: Fix bug by which accessing the real floppy disk |
| as B: in MS-DOS was broken. |
| * Simple menu system: allow tweaking of the screen layout. |
| * Simple menu system: better command-line editing, correctly |
| handle command lines above 256 characters. |
| * PXELINUX: revert memory allocation change that caused |
| problems on some network cards. |
| * MEMDISK: Try work around a bug on some BIOSes when no |
| physical floppy disk is present in the system. |
| * Enable the 16550A FIFOs, if present, when doing serial |
| console. |
| * New "totaltimeout" command establishes a timeout without |
| regard for any user input. |
| * Simple menu system: timeout behaviour now more in line with |
| user expectations. |
| * Simple menu system: "ontimeout" should now work correctly. |
| |
| Changes in 3.10: |
| * gcc 4.0.1 compilation fixes. |
| * Add support for querying the PCI BIOS in libcom32 |
| (used by ethersel et al.) |
| * Fix PCI handing (ethersel etc) on several old chipsets (and |
| VMWare.) |
| * Try to deal with systems with broken EBIOS. |
| * New API call to do "localboot". |
| * New API call to query features. |
| * New API call to run kernel image, a lower-level call than |
| "run command". See comboot.doc. |
| * Fix for bug in EBIOS code discovered by Arwin Vosselman. |
| * NOESCAPE security fix. |
| * Comments are now recognized even without a space following #. |
| * Fix incorrect handling of mixes of entries with and without |
| MENU PASSWD. |
| * The idle API call now harmlessly returns failure if it is a |
| no-op. That way the caller can decide whether or not to |
| bother invoking it again. |
| * Temporarily disable the idle API call on PXELINUX, due to |
| some platforms on which the idle API call seems to hang; this |
| problem has not yet been debugged. |
| * MEMDISK: the handling of DOSEMU-headered images was broken; |
| fix it. |
| * EXTLINUX: symlinks are now supported. |
| * Simple menu system: N and P now work correctly as hotkeys. |
| * MEMDISK: more BIOS bug workarounds. |
| |
| Changes in 3.09: |
| * gcc4 compilation fix. |
| * <BEL> (Ctrl-G) in message files now causes a beep. |
| * Reduce the command line to 511 characters; 1023 caused |
| memory overflows. |
| |
| Changes in 3.08: |
| * SYSLINUX: Fix performance regression (-s mode always |
| enabled.) |
| * Add API function for idle loop. |
| * libutil: Add do_idle() function for idle loop, make |
| get_key() use it. |
| * libutil: Add SHA-1 and base64 functions. |
| * Simple menu system: add password support. |
| * EXTLINUX: Sparse files now handled correctly. |
| * EXTLINUX: Large directories now handled correctly. |
| * ALL: At the prompt, Ctrl-X now forces text mode. |
| * Fix configuration file parsing error, that could cause |
| hangs. |
| * Rewritten advanced menuing system from Murali Ganapathy. |
| * MEMDISK: New "bigraw" mode to work around certain broken |
| BIOS flash programs. |
| * COM32 module to boot Multiboot systems, including Xen. See |
| com32/modules/mboot.doc. |
| * Max command line changed to 1023 characters. Note that the |
| kernel proper still can only handle 255 characters without |
| patching, and COM16 binaries can only handle 125 characters. |
| |
| Changes in 3.07: |
| * Fix chainloading (chain.c32). |
| * Fix zlib build problem. |
| * Use a private copy of <linux/ext2_fs.h>. |
| |
| Changes in 3.06: |
| * Fix typo that caused the ramdisk to load in the wrong place. |
| |
| Changes in 3.05: |
| * New API function "shuffle and boot"; allows COM32 modules to |
| load or construct (almost) arbitrarily complex objects, |
| e.g. a kernel and its initrd/initramfs in pieces, and have |
| the API core reorganize memory for booting. (A library API |
| for this function will be introduced in a later version.) |
| * The initrd= option now supports multiple filenames separated |
| by commas. This is mostly useful for initramfs, which can |
| be composed of multiple separate cpio or cpio.gz archives. |
| (Note: all files except the last one are zero-padded to a 4K |
| page boundary. This should not affect initramfs.) |
| * EXTLINUX: Fix API function 000Ah (get derivative-specific |
| info). |
| * libcom32/ethersel: Support PCI Config Mechanism #2 on |
| machines still infested with that hideous old hack. |
| * SYSLINUX: Fix directory-parsing bug. |
| |
| Changes in 3.02: |
| * SYSLINUX: The "unix" installer now sets the MS-DOS |
| attributes (hidden, system, readonly.) |
| * COM32 library: build the .lnx (test modules for running |
| under Linux) as architecture native modules, in case |
| i386 devel libraries aren't installed. |
| * EXTLINUX: Hack for systems which don't have BLKGETSIZE64 |
| defined in the standard header files. |
| * Simple menu system: minor aestetic improvements, and try to |
| work better over a serial console (speed, and readability on |
| monochrome terminal emulators.) |
| * New CONSOLE directive to control output on the video console |
| (useful for dealing with some broken serial-forwarding |
| BIOSes.) |
| * New com32 module "ethersel" for searching for an Ethernet |
| card and selecting the proper version of Etherboot. |
| * EXTLINUX: Allow the user to override the detected geometry. |
| Add help. |
| |
| Changes in 3.01: |
| * EXTLINUX, SYSLINUX: Fix compile errors on some systems. |
| * EXTLINUX: Default to zipdrive geometry (64 heads, 32 |
| sectors) if no other geometry can be detected. |
| |
| Changes in 3.00: |
| * SYSLINUX: Support FAT32 and EDD. As an unfortunate |
| consequence, LDLINUX.SYS is no longer an ordinary file; it |
| is block-mapped at install time, which means it can only be |
| written using the syslinux installers. |
| * SYSLINUX: Reorganize the source code for the installers; |
| each one of the installers (dos, win32, unix, mtools) is now |
| built in its own subdirectory. In particular, "mtools" is |
| the unprivileged installer which uses mtools; "unix" is the |
| privileged installer which uses system calls. |
| * SYSLINUX: Completely rewritten DOS installer in C. |
| * ALL: "label" statement information is now stored in a |
| compressed format, which means that a lot more labels are |
| permitted (500-1000 in a typical configuration, but depends |
| on the complexity.) |
| * EXTLINUX: New derivative, which boots from an ext2/ext3 |
| filesystem. |
| * SYSLINUX: The DOS and Win32 installers can now optionally |
| write the boot sector to a file instead of the real boot |
| sector. This is not supported in the Linux installers, |
| however. |
| * ALL: New NOESCAPE command, disables the "hold down the Shift |
| key to display the prompt" behaviour. |
| * New simple menu system, as an alternative to the advanced |
| menu system already present. See README.menu for details. |
| * PXELINUX: Filenames can now be prefixed with an IP address |
| or DNS name plus :: (e.g. 192.0.2.1::filename or |
| server.domain.com::filename), which downloads a file from an |
| alternate TFTP server, or just a :: (e.g. ::filename), which |
| suppresses the common pathname prefix. See pxelinux.doc. |
| * SYSLINUX: Add an -m option to the DOS and Win32 installers |
| to write an MBR and -a to mark the partition SYSLINUX is |
| being installed on active. |
| * MEMDISK: Give a way to query the boot loader type while |
| running MEMDISK; see memdisk/memdisk.doc and |
| sample/mdiskchk.c. |
| * mkdiskimage: substantially improved mkdiskimage which, among |
| other things, can now be used to initialize USB keys as |
| zipdrives; see README.usbkey for more information. |
| |
| Changes in 2.13: |
| * MEMDISK: Fix command-line parsing "brown paper bag" class |
| bug. |
| * MEMDISK: Add "raw" mode to support the DOS boot disk from |
| WinME/XP, which seems to deliberately crash the system |
| when someone uses the "INT 15h mover" highmem API. |
| * Make "make install" do something sane for the com32 |
| development environment. |
| * In the spec file, create a separate -devel RPM for the com32 |
| development environment. |
| |
| Changes in 2.12: |
| * Simple C library, based on klibc, for writing COM32 |
| programs. |
| * Fix the handling of file length in loading of COM32 |
| programs. |
| * MEMDISK: Work around a linker bug by rearranging the code to |
| not use the linker for the 16-bit code. |
| * SYSLINUX: If we're building on a machine without a Win32 |
| (mingw) compiler, just skip building syslinux.exe. |
| * ISOLINUX: Support non-mkisofs mastering programs, at least |
| as long as the image is single-session. For best results, |
| ISOLINUX should be the only boot loader installed. |
| * MEMDISK: Allow the user to specify that the simulated disk |
| should be write-protected. |
| |
| Changes in 2.11: |
| * ALL: Add an API call to get the configuration file name. |
| * SYSLINUX: Fix bug in 2.10 that prevented it from working |
| correctly for a lot of people. |
| * SYSLINUX: In the installer, make mtools a bit less fussy. |
| * Make the menu system compile with newer gcc's. |
| |
| Changes in 2.10: |
| * MEMDISK: Handle images compressed with zip as well as with |
| gzip. Some Windows-based image tools apparently generate |
| these kinds of images by default. Patch by Patrick |
| LoPresti. |
| * Major menu improvement from Murali Ganapathy. |
| * ISOLINUX: Wonderfully sick and brilliant workaround for |
| severe bugs in certain Award BIOSes; from Knut Petersen. |
| * SYSLINUX: Fix for the nomtools installed, from Frederic |
| Pasteleurs. |
| * PXELINUX: Fix handling of IP numbers in the ranges |
| 100-109 and 200-209. |
| * ALL: New option "allowoptions" (defaults to 1), which |
| controls if options are allowed on the command line or not. |
| * SYSLINUX: Support building under klibc (see the klibc |
| distribution for details.) |
| |
| Changes in 2.09: |
| * SYSLINUX: Remove residual setuid crap from |
| syslinux-nomtools. |
| * Handle video pages correctly when using the API functions. |
| * Handle compiling on an x86-64 platform correctly. |
| * Menu system from Murali Krishnan Ganapathy; see the menu |
| directory for information. |
| * COMBOOT: Allow COMBOOT programs to change screen text mode. |
| * COMBOOT: Correct the documentation of how to detect |
| SYSLINUX from COMBOOT!!!! |
| * COMBOOT: Fix "get key without echo" API function. |
| * SYSLINUX: Fix bug that affected the API open function. |
| * ALL: Improve the E820 memory parser, to work around some |
| buggy BIOSes. |
| |
| Changes in 2.08: |
| * Add new configuration command "ontimeout" to allow timeout |
| to have a different action than just pressing Enter. |
| * Add new configuration command "onerror" to allow a custom |
| command to be executed in case the kernel image is not found. |
| * Fix bugs in the COMBOOT/COM32 command-line parsing. APPEND |
| now works with COMBOOT/COM32 images. |
| * PXELINUX: Poll for ARP requests while sitting at the |
| prompt. This makes some boot servers a lot less unhappy. |
| * PXELINUX: Actually free sockets when we get a failure |
| (including file not found.) This bug would cause us to run |
| out of sockets and thus "go deaf" after a while. |
| * MEMDISK: Add an API to query for the existence of MEMDISK. |
| * SYSLINUX: Fix loading boot sectors (.bs/.bss) from floppy |
| disk. |
| * .c32 is now one of the extensions searched for |
| automatically. |
| * PXELINUX: RFBG.exe seems to randomly overwrite memory |
| location 0x5700. Thus, don't use it! |
| * PXELINUX: Change pathname length max from 63 to 127; change |
| max vkernels from 128 to 64. |
| * Support Ctrl-U -> kill entire command line input. |
| * The "samples" directory contains a (barely at all tested) |
| chain loading example, chain.c32, which may be used to |
| chainload local floppy disks and hard disks. Use with |
| "chain fdN" or "chain hdN [partition]"; N = 0 for the first |
| drive of each type. |
| |
| Changes in 2.07: |
| * MEMDISK: Workaround for BIOSes which go into a snit when |
| they get a RESET command for the floppy system when there is |
| no floppy in the system. |
| * PXELINUX: Add "ipappend 2", which passes the hardware |
| address of the boot interface to the kernel as a |
| command-line option. |
| * mkdiskimage: fix the generation of the end limit. |
| * PXELINUX: Fix multiple bugs in chainloading of other NBPs. |
| * MEMDISK: Fix bug that would occationally cause "ran out of |
| input data" when using compressed disk images. |
| * SYSLINUX: Updates for the win32 installer (from Lars Munch.) |
| * PXELINUX: PXELINUX-specific options are now recognized both |
| in a vendor-option-space (a.k.a. type 43 encapsulated) as |
| well as in a site-option-space (unencapsulated.) |
| * COM32: Don't crash when DS != 0. |
| * COMBOOT/COM32: Make file reading work correctly. Thanks to |
| Phung Chi Kien for submitting a test program. |
| |
| Changes in 2.06: |
| * ALL: Fix problem that would occationally cause a |
| boot failure, depending on the length of the kernel. |
| * ISOLINUX: Fix problem that would occationally cause a |
| boot failure, depending on the length of directories. |
| * SYSLINUX: Win32 installer now flushes buffers. |
| * ppmtolss16: Be fully compliant with the PNM spec; |
| actually process comments in the header and odd |
| alignments of the various parameters, as well as |
| "plain" (not raw) files and PBM and PGM files. |
| * PXELINUX: Lower the default MTU to 1472 in order to deal |
| with systems with slightly nonstandard MTUs, and PXE |
| stacks which don't defragment correctly. Unfortunately this |
| is very hard to test dynamically. |
| |
| Changes in 2.05: |
| * PXELINUX: Add a default query based on the hardware address |
| of the boot device. This is in lower case hexadecimal form |
| separated by dashes and including the hardware type, for |
| example, the Ethernet (type 1) address 88:99:AA:BB:CC:DD |
| would query the file pxelinux.cfg/01-88-99-aa-bb-cc-dd. |
| * PXELINUX: Fix bug involving non-IP-based config file names. |
| * SYSLINUX: New installer for WinNT-based systems, from Lars |
| Munch. |
| * MEMDISK: Fix handling of memory region overlap when |
| decompressing. Thanks to Mikhail Kupchik for identifying |
| the problem. |
| |
| Changes in 2.04: |
| * ALL: Reclaim even more low memory by observing that |
| comboot_seg == real_mode_seg is perfectly fine, and by the |
| fact that the 1000h segment managed to get unused in all |
| derivatives... |
| * PXELINUX: Attempt to negotiate full Ethernet-sized blocks |
| (1468 bytes) using the blksize option. |
| * SYSLINUX: Resurrect the old no-mtools version of the |
| installer, although as a root-only tool. Some distributors |
| have indicated that they need a small standalone installer. |
| * MEMDISK: Fix a memory offset computation error when |
| installing compressed disks which generally would cause |
| 1 MB of memory to be wasted. |
| * MEMDISK: Fix installing the E820 memory map. Calling |
| INT 15h AX=0E820h with MEMDISK 2.03 loaded would give a |
| completely corrupt memory map. |
| * SYSLINUX: Make libsyslinux a dynamic library, so that it can |
| be updated separately from client programs. The whole idea, |
| after all, is to enable alternate programs to become |
| syslinux installers. |
| * Include an rpm spec file in the distribution, so rpmbuild |
| -ta works. |
| |
| Changes in 2.03: |
| * Actually support comment lines in the configuration file. |
| * PXELINUX: Try to resolve some problems with stack switches. |
| * PXELINUX: Handle PXE stacks with broken routing. |
| With these workarounds, the remote install PXE boot floppy |
| (rbfg.exe) from Argon Technologies should work correctly. |
| * Fix problems with Perl scripts in UTF-8 locales. |
| * You probably need NASM 0.98.34 or later to compile this |
| version. 0.98.36 is recommended. |
| * MEMDISK: Now supports gzip compressed images. |
| |
| Changes in 2.02: |
| * SYSLINUX: Security flaws have been found in the SYSLINUX |
| installer when running setuid root. Rewrite the SYSLINUX |
| installer so it uses mtools instead. It therefore now |
| requires mtools (specifically mcopy and mattrib) to exist on |
| your system, but it will not require root privileges and |
| SHOULD NOT be setuid. |
| |
| Changes in 2.01: |
| * MEMDISK: Fix memory sizing bug when the ramdisk crosses the |
| 16 MB boundary. |
| * MEMDISK: Add a "pause" option to stop immediately before |
| booting, to read off the messages. |
| * MEMDISK: Support disk images with DOSEMU headers. |
| * Update the mkdiskimage script to handle newer mtools |
| versions, and be able to generate disk images with DOSEMU |
| headers (controlled by the -d option). |
| * Fix the COM32 sample program. |
| * PXELINUX, ISOLINUX: Fix some COMBOOT API calls. |
| * PXELINUX: Doc fix. |
| * Build SYSLINUX into a small library for encapsulation into |
| other programs (however, please keep in mind this is a GPL'd |
| library.) |
| * SYSLINUX: Make installer work with "owner" in /etc/fstab. |
| * SYSLINUX: Fix issue with working on nonpartitioned hard disk |
| devices. THIS CONFIGURATION IS NOT RECOMMENDED. |
| |
| Changes in 2.00: |
| * ALL: Add support for "COM32" (32-bit COMBOOT) images. |
| * ALL: Add an API for COMBOOT/COM32 images. See comboot.doc |
| for details. There is a C development environment for |
| COM32 being created; it should be ready at some point in |
| the future. |
| * Fix mbr.asm so that it actually works. |
| * SYSLINUX: The syslinux installer *SHOULD* now be safe to |
| run setuid root. |
| * PXELINUX: Fix bug where PXELINUX would override random |
| chunks of the UNDI code segment! Thanks to Kevin Tran for |
| finding this bug. |
| * ISOLINUX: Fix a bug related to slashes in pathnames. |
| * ISOLINUX: Fix a bug in handling initrds over 128 MB. |
| * ALL: Make the <Ctrl-V> key print out the version; this is |
| to help debugging. |
| * Add a small script, mkdiskimage, to create a DOS-formatted |
| hard disk image using mtools. This may be useful in |
| conjunction with MEMDISK. |
| * ISOLINUX: Search for a /boot/isolinux directory as well as |
| /isolinux. |
| * ALL: Fix a bug related to very long configuration files. |
| * PXELINUX: Work around a NASM bug which would result in no |
| delay before reset if an error occurs. |
| |
| Changes in 1.76: |
| * ISOLINUX: Remove code no longer used which caused hangs on |
| some Toshiba laptops. |
| |
| Changes in 1.75: |
| * ALL: NASM 0.98.32 or later is now required to build |
| SYSLINUX from sources. |
| * SYSLINUX: put back in the workaround for the BIOS floppy |
| table. This seems to be a requirement for "extended" floppy |
| formats to work correctly. |
| * SYSLINUX: No longer warn if one is trying to boot on a 286 |
| or older. The above BIOS workaround no longer fits if the |
| requirement to use only 8086-compatible code in the early |
| boot is maintained. It made sense in 1994, but in 2002 a |
| 286 or older is a museum object. |
| * SYSLINUX: Use a downright bizarre, stateful algorithm to try |
| to guess the maximum transfer size. I am *hoping* this will |
| cut down on the number of systems for which -s is required |
| to work at any acceptable speed. |
| * ISOLINUX: Add a few more workarounds for various broken El |
| Torito BIOSes. |
| * Make sure .depend files aren't accidentally packed... |
| * ALL: Fix bugs in the extension-detect code; this caused |
| files like COMBOOT images and CD boot sectors to be |
| mis-identified as Linux kernels and rejected. |
| * ALL: Fix the return from COMBOOT. |
| * ALL: Do some of the early groundwork for supporting DOS |
| system calls in COMBOOT. |
| * Get rid of unnecessary "near" directives, making the code |
| bigger. |
| * PXELINUX: Put the PXE stack back in the init state before |
| invoking a chain-loaded NBP. |
| * PXELINUX: Actually found the combination of calls that |
| allows some (most?) PXE 2+ stacks to be unloaded from memory |
| properly. |
| * PXELINUX: Add "keeppxe" command-line option to disable |
| the standard unloading of the PXE stack. |
| |
| Changes in 1.74: |
| * SYSLINUX: fix bug that would cause valid kernel images to be |
| labelled "invalid". |
| |
| Changes in 1.73: |
| * Work on removing gratuitous differences between modules. |
| * Break up the source in common and module-specific files. |
| * PXELINUX: Allow chaining of other PXE NBPs. |
| * ISOLINUX: Allow loading "CD-ROM boot sectors". |
| * ALL: generalize the definition of a boot sector/NBP. |
| |
| Changes in 1.72: |
| * PXELINUX, ISOLINUX: Fix bugs in the new core code. |
| |
| Changes in 1.71: |
| * Fix a "brown paper bag" class bug in the new core code. |
| |
| Changes in 1.70: |
| * Major code restructuring. |
| * Relax the conventional memory limits somewhat. |
| * MEMDISK: Set up the "version number string" pointer in the |
| header correctly. |
| * SYSLINUX: Fix, again, "the bug that won't die": the use of |
| the offset parameter with the SYSLINUX installer. |
| * SYSLINUX: Fix possible superblock corruption problem in the |
| SYSLINUX installer. |
| |
| Changes in 1.67: |
| * Handle bug in the location of initrd. |
| |
| Changes in 1.66: |
| * MEMDISK: Make compile with newer versions of gcc. |
| |
| Changes in 1.65: |
| * ISOLINUX: Support booting disk image files (to boot DOS or |
| other non-Linux operating systems), *IF* the BIOS works |
| correctly; unfortunately many BIOSes apparently don't. |
| * Support Linux boot protocol version 2.03 (explicitly |
| specify the initrd address limit.) |
| * Handle small "pseudo-kernels"; images that use the Linux |
| kernel boot protocols but are less than 64K in size. |
| * MEMDISK: New subsystem; this is a driver which allows |
| legacy OSes to boot using an in-memory simulated disk. |
| See memdisk/memdisk.doc for more info. |
| * PXELINUX, ISOLINUX: Correctly handle files larger than 65535 |
| blocks (32 MB for PXELINUX, 128 MB for ISOLINUX.) |
| * PXELINUX: Make a best-effort attempt at freeing all memory |
| claimed. From the looks of it, it will fail on most PXE |
| stacks. |
| |
| Changes in 1.64: |
| * Limited support for hardware flow control when using a |
| serial port console. |
| * Support specifying the serial port I/O address explicitly. |
| * Make DOS installer hopefully behave more nicely when used on |
| recent Windows versions. |
| * Fix returning to text mode when a font has been specified. |
| * Attempt to detect missing serial port hardware and disable |
| the serial port if there is nothing there. |
| |
| Changes in 1.63: |
| * Make the ppmtolss16 program handle color conversion more |
| correctly. |
| * Clean up "make install" target, honour INSTALLROOT if it |
| exists. |
| * SYSLINUX: Fix stack-smash bug identified by Steffen |
| Winterfeldt. |
| * Hopefully fix return-to-text-mode on some graphics cards. |
| * ISOLINUX: Bug workaround for Award BIOS 4.51, and perhaps |
| other buggy BIOSes as well. |
| |
| Changes in 1.62: |
| * PXELINUX: Allow the DHCP server to override the |
| configuration file name and pathname prefix, using |
| "site-specific" DHCP options. |
| * PXELINUX: Documentation fixes. |
| * PXELINUX: Fix the "ipappend" option; the last two values |
| were reversed vs. what the kernel expected. |
| * Introduce a way to return to text mode once we are already |
| in graphics mode. This may be useful for F-key help |
| screens. |
| * Fix several bugs in the way return to text mode was handled. |
| |
| Changes in 1.61: |
| * ISOLINUX: Support full pathname searches. Max length for a |
| pathname is 255 characters. As a result, only 64 "label" |
| statements are supported in ISOLINUX. |
| * PXELINUX: Max filename length extended to 63 characters. |
| |
| Changes in 1.60: |
| * Add support for graphical splash screens. |
| * Add mode control characters, which allows you to control |
| message display output depending on output mode (text, |
| graphics, or serial port.) |
| * ISOLINUX: New program, which boots Linux from a CD-ROM |
| without using floppy emulation mode. See isolinux.doc for |
| more details. |
| * PXELINUX: Don't search for boot sector file types, since |
| they don't work anyway. |
| * SYSLINUX: Document the LOCK command for Win9x, and the error |
| dialog box for WinNT/2K. |
| |
| Changes in 1.54: |
| * PXELINUX: Fix code for finding !PXE from PXENV+. This was |
| due to a spec bug; match the most recent spec since that |
| seems to be what implementations actually do. |
| * SYSLINUX: Add some smarts to the boot sector, which |
| hopefully should reduce the number of systems which require |
| stupid mode ("syslinux -s"). |
| * PXELINUX: Document further some of the pathologies with old |
| PXE stacks. |
| * When specifying a "default" command line, no longer |
| automatically appent "auto". See the "DEFAULT" command in |
| syslinux.doc for more information. |
| * PXELINUX: Clean up the allocation of local socket numbers. |
| |
| Changes in 1.53: |
| * PXELINUX: Rename pxelinux.bin to pxelinux.0, to match what |
| most PXE servers seem to expect. |
| * PXELINUX: Update the DHCP/boot server setup documentation. |
| * PXELINUX: Support new "localboot" option for "label" |
| sections. |
| * PXELINUX: More robust parsing of DHCP/boot server packets. |
| * PXELINUX: Include a small utility program "gethostip" to |
| compute hexadecimal IP addresses. |
| |
| Changes in 1.52: |
| * PXELINUX: Fix bugs introduced by new A20 code. (SYSLINUX |
| has also been changed for code consistency reasons, but I'm |
| pretty sure the changes are don't care on SYSLINUX.) |
| * Documentation updates. |
| * PXELINUX: Add "ipappend" option to generate an ip= option to |
| the kernel. |
| |
| Changes in 1.51: |
| * PXELINUX: Not all PXE stacks fill in the IP address for a |
| type 3 cached info query. Use a type 2 cached info query |
| for this information (only.) |
| * Yet another attempt at A20 coding. Now support BIOS call |
| 15:2401 as well, and handle machines which always have A20 |
| on separately. |
| * Support memory detection using INT 15h, AX=0E820h. BIOS |
| manufacturers have apparently gotten sloppy about keeping |
| INT 15h, AX=0E801h working properly. |
| * Don't issue <CR><LF> onto the serial port when we're doing |
| screen wraparound. |
| |
| Changes in 1.50: |
| * Yet another A20-code update. It seems some "legacy-free" |
| machines and embedded gear simply don't have a KBC to talk |
| to, and that waiting for one will wait forever. Sigh. |
| |
| Changes in 1.49: |
| * SYSLINUX: Implement a hack for BIOS drivers which hog significant |
| chunks of low memory during boot. (Note: PXELINUX already |
| had this modification. SYSLINUX does still require that the |
| low 512K is available; PXELINUX requires 384K. Machines |
| with a physical memory hole in the low 640K cannot boot |
| Linux no matter what.) Depending what the reason is for the |
| memory hole, a new kernel (2.4.0-test3-pre3 or later) may be |
| required. |
| * SYSLINUX: Default installer binary now compiled against |
| glibc 2.1. If this is inappropriate for your system and you |
| still want to use the offical version of SYSLINUX, please |
| follow the instructions in "distrib.doc" to rebuild the |
| installer. |
| * SYSLINUX: Linux installer program now supports -o <offset> |
| option which does a loopback mount with the |
| -o loop,offset=<> option. Useful to run SYSLINUX on an |
| individual partition of a whole-harddisk image. |
| * Include the source code to a Master Boot Record (MBR) |
| functionally equivalent to the one installed DOS except it |
| includes EBIOS support, and should be resistant to geometry |
| changes. The MBR code is public domain. |
| * PXELINUX: Fix "double p" bug: if the tftp prefix was null, |
| all filenames would get a "p" preprended, e.g. |
| "ppxelinux.cfg" and "pvmlinux". |
| |
| Changes in 1.48: |
| * PXELINUX: Workaround for PXE ROMs based on the Intel PXE PDK |
| 3.0 build 071 and earlier: missing !PXE structure pointer. |
| * PXELINUX: Handle larger BOOTP/DHCP packages. |
| * PXELINUX: The command line passing was broken; fix. |
| * PXELINUX: Make COMBOOT images work. |
| * PXELINUX: Documentation on how to make booting work using |
| the PDK 3.0-derived clients, which aren't so generous as to |
| allow booting with only "PXEClient" specified. |
| |
| Changes in 1.47: |
| * PXELINUX: RFC 1123 states that a TFTP implementation MUST |
| use adaptive timeout, "at least an exponential backoff of |
| retransmission timeout is necessary." Implement a very |
| simple exponential backoff for retransmits. |
| * PXELINUX: Updated documentation, including pointer to new |
| TFTP server. |
| * PXELINUX: When sending ERROR due to bad OACK, use the proper |
| destination port number (why are TFTP port numbers so odd?) |
| * PXELINUX: If the boot dies in the middle somewhere, |
| eventually give up and reset the machine (unattended |
| operation.) |
| |
| Changes in 1.46: |
| * New program PXELINUX to do network booting using a |
| PXE-compliant (Pre-Execution Environment) network booting |
| PROM. See pxelinux.doc for details. |
| |
| Changes in 1.45: |
| * Serial console support. See syslinux.doc for details. |
| |
| Changes in 1.44: |
| * Change HIGHMEM_MAX to 38000000h to (hopefully) avoid the |
| kernel stepping on it; 3f000000h was apparently a higher |
| limit than the kernel used! |
| |
| Changes in 1.43: |
| * Add sys2ansi.pl script to display the contents of a |
| colorized SYSLINUX file. |
| * Changed the io_delay once again, after a report that the |
| old delay port causes hangs on some systems. |
| |
| Changes in 1.42: |
| * Frob the "fast A20 gate" port as well as the keyboard |
| controller; will this help systems with problems? |
| * Be even more paranoid about A20, unfortunately even this |
| seems to be not paranoid enough... what I don't understand |
| is that if there is hardware out there *this broken*, how |
| can it run Linux at all? Report an error message rather |
| than hang forever if A20 is stuck. |
| * Include some intermediate files in the distribution, plus |
| provide a "make installer" target for distributors to relink |
| the install programs only. I would prefer the syslinux boot |
| loader proper to be "binary clean" for debuggablity -- use |
| "make clean ; make installer" to rebuild the installers only. |
| |
| Changes in 1.41: |
| * Don't get confused by directories, volume labels, or VFAT |
| long names. |
| * Use INT 15h, AX=0E801h to query memory size before trying |
| INT 15h, AH=88h. This not only provides more headroom |
| between the kernel and the initrd on large-memory machines, |
| but it appears some recent BIOSes actually have started |
| returning garbage for the AH=88h (older) call. |
| * Trust high memory beyond the 15 MB mark if the user has |
| specified it, or if obtained with INT 15h, AH=0E801h (with |
| no memory holes above 1 MB.) |
| |
| Changes in 1.40: |
| * Increase A20M delay and put in a test to avoid problems on |
| certain IBM Thinkpads (thanks to Donnie Barnes of RedHat |
| for vital info on this one.) |
| * Support COMBOOT style boot command images. |
| * Support chain loading (foreign operating systems, e.g. DOS). |
| * Include a new "copybs" DOS utility to copy a boot sector to |
| a file (under Linux, use "dd".) |
| * Fix the DOS installer to work for disks over 32 MB. |
| * SYSLINUX should now handle disks with more than 65536 tracks. |
| |
| Changes in 1.37: |
| * Fix a bug that caused "label" statements in syslinux.cfg to |
| not be handled properly. |
| * Updated the documentation. Among other things, we now allow |
| up to 128 "label" statements. |
| |
| Changes in 1.36: |
| * Fix for booting old (pre-initrd) kernels. |
| * It seems at least some versions of OS/2 doesn't set up all |
| the fields in the superblock correctly. Account for that. |
| * Fix bug that caused boot failure when using the mem= option. |
| |
| Changes in 1.35: |
| * Loading from partitions now should work properly. (Actually |
| tested, this time. You should even be able to dd a floppy |
| to a partition and boot from it.) |
| * Removed large workaround code for an alleged ancient BIOS |
| bug I have never actually seen. The -s option should work |
| on those machines, anyway. |
| * Support for simple keyboard remappings, same as used by |
| LILO (once again to support localization.) The program |
| keytab-lilo.pl from the LILO distribution included to |
| generate such maps. |
| * Added a "safe, slow and stupid" (-s) option to the |
| installers. This option will lobotomize the boot sector to |
| hopefully work on even very buggy BIOSes. |
| |
| Changes in 1.34: |
| * Ability to load a VGA font on bootup (for localized Linux |
| distributions.) |
| |
| Changes in 1.33: |
| * Bug fix in the Linux installer. |
| * Added a workaround for a bug in certain AMI/Intel BIOSes |
| when booting from CD-ROM. |
| * Documentation changes. |
| |
| Changes in 1.32: |
| * FAT16 filesystems are now supported. |
| |
| Changes in 1.31: |
| * Now compiles under Linux, using NASM, rather than using |
| Turbo Assembler under DOS. See http://www.cryogen.com/Nasm |
| for information about NASM. |
| * Linux-hosted SYSLINUX installer, as well as a |
| rewritten DOS installer (now is written in assembler, so we |
| don't need Turbo C.) |
| |
| Changes in 1.30: |
| * Added support for loading bzImage and initrd loading, and made |
| SYSLINUX new-setup-code aware (SYSLINUX 1.30 id=0x31). |
| * Added LILO-style kernel labels; see the LABEL and IMPLICIT |
| keywords in README file. |
| * Added support for colorization of intro and help screens. |
| * The vga= option is now handled correctly. |
| * Massive rewrite of large chunks of the code in order to |
| support the first two new features. |
| |
| Changes in 1.20: |
| * Added simple online help at the "boot:" prompt. |
| * Removed 2880K image as I no longer have access to such a |
| floppy drive. (Donations accepted!!) |
| * Decided to distribute the source in a subdirectory rather |
| than in a nested zipfile. |
| |
| Changes in 1.11: |
| * Removed a sanity check which would cause booting to fail on |
| Phoenix BIOS version 4.03. Apparently this BIOS is buggy. |
| |
| Changes in 1.10: |
| * Added configuration file SYSLINUX.CFG. This file contains all |
| configurable options, and can be edited from any OS which can |
| access an MS-DOS filesystem; there is no longer a need to run |
| SYSLINUX.EXE except to write the boot sector. |
| * Default command line now given by "default" line in config |
| file. |
| * LINUXMSG.TXT and BOOTMSG.TXT hard-coded file names replaced by |
| "display" and "prompt" lines in config file. |
| * LILO-style option appending now supported ("append" line in |
| config file). |
| * Prompt timeout is now supported ("timeout" line in config |
| file). The timeout is cancelled when anything is typed on the |
| command line. |
| * Pressing <ESC> or <Ctrl-C> at the Loading... stage now aborts |
| the kernel loading in progress and returns the user to the |
| boot: prompt. |
| * The installer now automatically sets the READONLY flag on |
| LDLINUX.SYS. |
| * Added 2880K disk image. |
| |
| Changes in 1.03: |
| * Fixed bug that would prevent booting from double-density |
| floppies and other DOS filesystems with multiple sectors per |
| cluster. |
| * Added 720K disk image. |
| * Changed default kernel name on disk images to LINUX. |
| |
| Changes in 1.02: |
| * Fixed bug that would garble the command line on recent kernels |
| with more than 4 sectors of setup code (this wasn't really a |
| *bug*; rather, a kernel change broke the code. Unfortunately |
| the Linux boot interface is still sorely undocumented). |
| * Added BOOTMSG.TXT file support (message file which does not |
| force display of the boot prompt). |
| |
| Changes in 1.01: |
| * Fixed bug on some (most?) 386 BIOSes would require two boot |
| attempts. |
