|  | their lack of a BIOS setup menu and APM support. | 
|  |  | 
|  | On these machines, all system configuration is handled through the | 
|  | ACPI.  This driver is required for access to controls not covered |

|  | etc. | 
|  |  | 
|  | This driver differs from the non-ACPI Toshiba laptop driver (located | 
|  | under "Processor type and features") in several aspects. | 
|  | Configuration is accessed by reading and writing text files in the | 
|  | /proc tree instead of by program interface to /dev.  Furthermore, no |
