17          Advanced Configuration and Power Interface (ACPI) support for
18          Linux requires an ACPI compliant platform (hardware/firmware),
19          and assumes the presence of OS-directed configuration and power
20          management (OSPM) software.  This option will enlarge your
21          kernel by about 70K.
22
23          Linux ACPI provides a robust functional replacement for several
24          legacy configuration and power management interfaces, including
25          the Plug-and-Play BIOS specification (PnP BIOS), the
26          MultiProcessor Specification (MPS), and the Advanced Power
27          Management (APM) specification.  If both ACPI and APM support
28          are configured, whichever is loaded first shall be used.
29
30          The ACPI SourceForge project contains the latest source code,
31          documentation, tools, mailing list subscription, and other
32          information.  This project is available at:
33          <http://sourceforge.net/projects/acpi>
34
35          Linux support for ACPI is based on Intel Corporation's ACPI
36          Component Architecture (ACPI CA).  For more information see:
37          <http://developer.intel.com/technology/iapc/acpi>
38
39          ACPI is an open industry specification co-developed by Compaq,
40          Intel, Microsoft, Phoenix, and Toshiba.  The specification is
41          available at:
42          <http://www.acpi.info>

51        ---help---
52          This option adds support for ACPI suspend states.
53
54          With this option, you will be able to put the system "to sleep".
55          Sleep states are low power states for the system and devices. All
56          of the system operating state is saved to either memory or disk
57          (depending on the state), to allow the system to resume operation
58          quickly at your request.
59
60          Although this option sounds really nifty, barely any of the device
61          drivers have been converted to the new driver model and hence few
62          have proper power management support.
63
64          This option is not recommended for anyone except those doing driver

175        ---help---
176          This driver provides support for extra features of ACPI-compatible
177          ASUS laptops. As some of Medion laptops are made by ASUS, it may also
178          support some Medion laptops (such as 9675 for example).  It makes all
179          the extra buttons generate standard ACPI events that go through
180          /proc/acpi/events, and (on some models) adds support for changing the
181          display brightness and output, switching the LCD backlight on and off,
182          and most importantly, allows you to blink those fancy LEDs intended
183          for reporting mail and wireless status.
184
185          Note: display switching code is currently considered EXPERIMENTAL,
186          toying with these values may even lock your machine.
187         
188          All settings are changed via /proc/acpi/asus directory entries. Owner
189          and group for these entries can be set with asus_uid and asus_gid
190          parameters.

192          More information and a userspace daemon for handling the extra buttons
193          at <http://sourceforge.net/projects/acpi4asus/>.
194         
195          If you have an ACPI-compatible ASUS laptop, say Y or M here. This
196          driver is still under development, so if your laptop is unsupported or
197          something works not quite as expected, please use the mailing list
198          available on the above page (acpi4asus-user@lists.sourceforge.net)

228        ---help---
229          This driver adds support for access to certain system settings
230          on "legacy free" Toshiba laptops.  These laptops can be recognized by
231          their lack of a BIOS setup menu and APM support.
232
233          On these machines, all system configuration is handled through the
234          ACPI.  This driver is required for access to controls not covered
235          by the general ACPI drivers, such as LCD brightness, video output,
236          etc.
237
238          This driver differs from the non-ACPI Toshiba laptop driver (located
239          under "Processor type and features") in several aspects.
240          Configuration is accessed by reading and writing text files in the
241          /proc tree instead of by program interface to /dev.  Furthermore, no
242          power management functions are exposed, as those are handled by the
243          general ACPI drivers.
