tristate "Advanced Power Management Emulation"

---help---
APM is a BIOS specification for saving power using several different
techniques. This is mostly useful for battery powered laptops with
battery status information, and user-space programs will receive
notification of APM "events" (e.g. battery status change).
- If you select "Y" here, you can disable actual use of the APM
- BIOS by passing the "apm=off" option to the kernel at boot time.
-
- Note that the APM support is almost completely disabled for
- machines with more than one CPU.
-
In order to use APM, you will need supporting software. For location
and more information, read <file:Documentation/pm.txt> and the
Battery Powered Linux mini-HOWTO, available from
manpage ("man 8 hdparm") for that), and it doesn't turn off
VESA-compliant "green" monitors.
- This driver does not support the TI 4000M TravelMate and the ACER
- 486/DX4/75 because they don't have compliant BIOSes. Many "green"
- desktop machines also don't have compliant BIOSes, and this driver
- may cause those machines to panic during the boot phase.
-
Generally, if you don't have a battery in your machine, there isn't
much point in using this driver and you should say N. If you get
random kernel OOPSes or reboots that don't seem to be related to
anything, try disabling/enabling this option (or disabling/enabling
APM in your BIOS).
- Some other things you should try when experiencing seemingly random,
- "weird" problems:
-
- 1) make sure that you have enough swap space and that it is
- enabled.
- 2) pass the "no-hlt" option to the kernel
- 3) switch on floating point emulation in the kernel and pass
- the "no387" option to the kernel
- 4) pass the "floppy=nodma" option to the kernel
- 5) pass the "mem=4M" option to the kernel (thereby disabling
- all but the first 4 MB of RAM)
- 6) make sure that the CPU is not over clocked.
- 7) read the sig11 FAQ at <http://www.bitwizard.nl/sig11/>
- 8) disable the cache from your BIOS settings
- 9) install a fan for the video card or exchange video RAM
- 10) install a better fan for the CPU
- 11) exchange RAM chips
- 12) exchange the motherboard.
-
- To compile this driver as a module, choose M here: the
- module will be called apm.
