+ APM is a BIOS specification for saving power using several different
+ techniques. This is mostly useful for battery powered laptops with
+ APM compliant BIOSes. If you say Y here, the system time will be
+ reset after a RESUME operation, the /proc/apm device will provide
+ battery status information, and user-space programs will receive
+ notification of APM "events" (e.g. battery status change).
+

+ 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
+ <http://www.tldp.org/docs.html#howto>.
+
+ This driver does not spin down disk drives (see the hdparm(8)
+ 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.
