349b4f9fe12SLen Brown	  If you have an ACPI-compatible ASUS laptop, say Y or M here. This
350b4f9fe12SLen Brown	  driver is still under development, so if your laptop is unsupported or
351b4f9fe12SLen Brown	  something works not quite as expected, please use the mailing list
352b4f9fe12SLen Brown	  available on the above page (acpi4asus-user@lists.sourceforge.net).

354b4f9fe12SLen Brown	  NOTE: This driver is deprecated and will probably be removed soon,
355b4f9fe12SLen Brown	  use asus-laptop instead.

366b4f9fe12SLen Brown	  This driver adds support for access to certain system settings
367b4f9fe12SLen Brown	  on "legacy free" Toshiba laptops.  These laptops can be recognized by
368b4f9fe12SLen Brown	  their lack of a BIOS setup menu and APM support.
369b4f9fe12SLen Brown
370b4f9fe12SLen Brown	  On these machines, all system configuration is handled through the
371b4f9fe12SLen Brown	  ACPI.  This driver is required for access to controls not covered
372b4f9fe12SLen Brown	  by the general ACPI drivers, such as LCD brightness, video output,
373b4f9fe12SLen Brown	  etc.

375b4f9fe12SLen Brown	  This driver differs from the non-ACPI Toshiba laptop driver (located
376b4f9fe12SLen Brown	  under "Processor type and features") in several aspects.
377b4f9fe12SLen Brown	  Configuration is accessed by reading and writing text files in the
378b4f9fe12SLen Brown	  /proc tree instead of by program interface to /dev.  Furthermore, no
379b4f9fe12SLen Brown	  power management functions are exposed, as those are handled by the
380b4f9fe12SLen Brown	  general ACPI drivers.

385b4f9fe12SLen Brown	  If you have a legacy free Toshiba laptop (such as the Libretto L1
386b4f9fe12SLen Brown	  series), say Y.
