 <h3 id="_path_rules">PATH RULES</h3>
 <div class="paragraph"><p>The current working directory is <strong>always</strong> searched first, before PATH,
 when attempting to open a filename. The current working directory is
 not affected when specifying a file with an absolute path. For
 example, given the following file system layout,</p></div>
 <div class="literalblock">
 <div class="content">
 <pre><code>/boot/
         /bin/
                 ls.c32
                 libls.c32
         /foo/
                 libls.c32</code></pre>
 </div></div>
 <div class="paragraph"><p>assuming that the current working directory is /boot/foo, and assuming
 that libls.c32 is a dependency of ls.c32, executing /boot/bin/ls.c32
 will cause /boot/foo/libls.c32 to be loaded, not /boot/bin/libls.c32,
 even if /boot/bin is specified in the PATH directive of a config file.</p></div>
 <div class="paragraph"><p>The reason that things work this way is that typically a user will
 install all library files in the Syslinux installation directory, as
 specified with the --directory installer option. This method allows
 the user to omit the PATH directive from their config file and still
 have things work correctly.</p></div>

	<div class="paragraph"><p>The command line prompt supports the following keystrokes:</p></div>
	<div class="literalblock">
	<div class="content">
	<pre><code><Enter> boot specified command line
	<BackSpace> erase one character
	<Ctrl-U> erase the whole line
	<Ctrl-V> display the current Syslinux version
	<Ctrl-W> erase one word
	<Ctrl-X> force text mode
	<Tab> list matching labels

	<Ctrl-F><digit> equivalent to F1..F10

	<h3 id="_working_directory">WORKING DIRECTORY</h3>
	<div class="paragraph"><p>At start, the initial working directory for <strong>SYSLINUX</strong>/<strong>ISOLINUX</strong> will
	be the directory containing the initial configuration file. If no
	configuration file is found, <strong>SYSLINUX</strong> should default to the
	install-time working directory, however this is a known issue with some
	versions including 4.06.</p></div>
	<div class="paragraph"><p>At start, the initial working directory for <strong>PXELINUX</strong> will be the
	parent directory of pxelinux.0 unless overridden with DHCP option 210.
	If no configuration file is found, <strong>PXELINUX</strong> will start a timer to
	reboot the system in an attempt to restart the boot process and resolve
	a possible transient issue.</p></div>
	</div>
	<div class="sect2">
	<h3 id="_alternate_filenames">ALTERNATE FILENAMES</h3>
	<div class="paragraph"><p>For kernel-like file names given on the command line, <strong>Syslinux</strong> will
	attempt to append file name extensions to the specified file name when
	the file is not found in the following order: .0[<strong>PXELINUX</strong> only],
	.bin[<strong>ISOLINUX</strong> only], .bs[<strong>SYSLINUX</strong> only], .bss[<strong>SYSLINUX</strong> only],
	.c32, .cbt[Up to 4.06], .com[Up to 4.06] and .img[<strong>ISOLINUX</strong> 1.65-4.04 only].</p></div>
	</div>
	<div class="sect2">
	<h3 id="_path_rules">PATH RULES</h3>
	<div class="paragraph"><p>The current working directory is <strong>always</strong> searched first, before PATH,
	when attempting to open a filename. The current working directory is
	not affected when specifying a file with an absolute path. For
	example, given the following file system layout,</p></div>
	<div class="literalblock">
	<div class="content">
	<pre><code>/boot/
	/bin/
	ls.c32
	libls.c32
	/foo/
	libls.c32</code></pre>
	</div></div>
	<div class="paragraph"><p>assuming that the current working directory is /boot/foo, and assuming
	that libls.c32 is a dependency of ls.c32, executing /boot/bin/ls.c32
	will cause /boot/foo/libls.c32 to be loaded, not /boot/bin/libls.c32,
	even if /boot/bin is specified in the PATH directive of a config file.</p></div>
	<div class="paragraph"><p>The reason that things work this way is that typically a user will
	install all library files in the Syslinux installation directory, as
	specified with the --directory installer option. This method allows
	the user to omit the PATH directive from their config file and still
	have things work correctly.</p></div>
