-ACPI ASUS/Medion Laptop Extras
-CONFIG_ACPI_ASUS
- This driver provides support for extra features of ACPI-compatible
- ASUS laptops. As some of Medion laptops are made by ASUS, it may also
- support some Medion laptops (such as 9675 for example). It makes all
- the extra buttons generate standard ACPI events that go through
- /proc/acpi/events, and (on some models) adds support for changing the
- display brightness and output, switching the LCD backlight on and off,
- and most importantly, allows you to blink those fancy LEDs intended
- for reporting mail and wireless status.
-
- All settings are changed via /proc/acpi/asus directory entries. Owner
- and group for these entries can be set with asus_uid and asus_gid
- parameters.

-ACPI Toshiba Laptop Extras
-CONFIG_ACPI_TOSHIBA
- This driver adds support for access to certain system settings
- on "legacy free" Toshiba laptops. These laptops can be recognized by
- 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
- by the general ACPI drivers, such as LCD brightness, video output,
- 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
- power management functions are exposed, as those are handled by the
- general ACPI drivers.

- More information about this driver is available at
