For location656 and more information, read <file:Documentation/pm.txt> and the657 Battery Powered Linux mini-HOWTO, available from···655 manpage ("man 8 hdparm") for that), and it doesn't turn off656 VESA-compliant "green" monitors.657658- This driver does not support the TI 4000M TravelMate and the ACER659- 486/DX4/75 because they don't have compliant BIOSes. Many "green"660- desktop machines also don't have compliant BIOSes, and this driver661- may cause those machines to panic during the boot phase.662-663 Generally, if you don't have a battery in your machine, there isn't664 much point in using this driver and you should say N. If you get665 random kernel OOPSes or reboots that don't seem to be related to666 anything, try disabling/enabling this option (or disabling/enabling667 APM in your BIOS).668-669- Some other things you should try when experiencing seemingly random,670- "weird" problems:671-672- 1) make sure that you have enough swap space and that it is673- enabled.674- 2) pass the "no-hlt" option to the kernel675- 3) switch on floating point emulation in the kernel and pass676- the "no387" option to the kernel677- 4) pass the "floppy=nodma" option to the kernel678- 5) pass the "mem=4M" option to the kernel (thereby disabling679- all but the first 4 MB of RAM)680- 6) make sure that the CPU is not over clocked.681- 7) read the sig11 FAQ at <http://www.bitwizard.nl/sig11/>682- 8) disable the cache from your BIOS settings683- 9) install a fan for the video card or exchange video RAM684- 10) install a better fan for the CPU685- 11) exchange RAM chips686- 12) exchange the motherboard.687-688- To compile this driver as a module, choose M here: the689- module will be called apm.690691endmenu692
