  15. Advanced Configuration and Power Interface (ACPI) support for
  16. Linux requires an ACPI compliant platform (hardware/firmware),
  17. and assumes the presence of OS-directed configuration and power
  18. management (OSPM) software. This option will enlarge your
  19. kernel by about 70K.
  20. Linux ACPI provides a robust functional replacement for several
  21. legacy configuration and power management interfaces, including
  22. the Plug-and-Play BIOS specification (PnP BIOS), the
  23. MultiProcessor Specification (MPS), and the Advanced Power
  24. Management (APM) specification. If both ACPI and APM support
  25. are configured, whichever is loaded first shall be used.
  26. The ACPI SourceForge project contains the latest source code,
  27. documentation, tools, mailing list subscription, and other
  28. information. This project is available at:
  29. <http://sourceforge.net/projects/acpi>
  30. Linux support for ACPI is based on Intel Corporation's ACPI
  31. Component Architecture (ACPI CA). For more information see:
  32. <http://developer.intel.com/technology/iapc/acpi>
  33. ACPI is an open industry specification co-developed by Compaq,
  34. Intel, Microsoft, Phoenix, and Toshiba. The specification is

  170. and most importantly, allows you to blink those fancy LEDs intended
  171. for reporting mail and wireless status.
  172. Note: display switching code is currently considered EXPERIMENTAL,
  173. toying with these values may even lock your machine.
  174. All settings are changed via /proc/acpi/asus directory entries. Owner

  181. something works not quite as expected, please use the mailing list
  182. available on the above page (acpi4asus-user@lists.sourceforge.net).

  192. their lack of a BIOS setup menu and APM support.
  193. On these machines, all system configuration is handled through the
  194. ACPI. This driver is required for access to controls not covered
  195. by the general ACPI drivers, such as LCD brightness, video output,
  196. etc.
  197. This driver differs from the non-ACPI Toshiba laptop driver (located
  198. under "Processor type and features") in several aspects.
  199. Configuration is accessed by reading and writing text files in the
  200. /proc tree instead of by program interface to /dev. Furthermore, no
  201. power management functions are exposed, as those are handled by the
  202. general ACPI drivers.
