26 The Extended Industry Standard Architecture (EISA) bus was

29 The EISA bus provided some of the features of the IBM MicroChannel
30 bus while maintaining backward compatibility with cards made for
31 the older ISA bus. The EISA bus saw limited use between 1988 and
32 1995 when it was made obsolete by the PCI bus.

499 are still copied to RAM. The XIP kernel is not compressed since
500 it has to run directly from flash, so it will take more space to

586 This is an experimental much faster emulator which now also has full

590 It should be sufficient for most programs. It may be not suitable

629 "Power Management" means that parts of your computer are shut

632 and ACPI. If you want to use either one, say Y here and then also
633 to the requisite support below.

635 Power Management is most important for battery powered laptop

637 page on the WWW at <http://www.linux-on-laptops.com/> or

645 ---help---
646 APM is a BIOS specification for saving power using several different
647 techniques. This is mostly useful for battery powered laptops with
648 APM compliant BIOSes. If you say Y here, the system time will be
649 reset after a RESUME operation, the /proc/apm device will provide
650 battery status information, and user-space programs will receive
651 notification of APM "events" (e.g. battery status change).
652
Linus Torvalds1da177e2005-04-16 15:20:36 -0700653 In order to use APM, you will need supporting software. For location
654 and more information, read <file:Documentation/pm.txt> and the
655 Battery Powered Linux mini-HOWTO, available from
656 <http://www.tldp.org/docs.html#howto>.

658 This driver does not spin down disk drives (see the hdparm(8)
659 manpage ("man 8 hdparm") for that), and it doesn't turn off
660 VESA-compliant "green" monitors.
661
Linus Torvalds1da177e2005-04-16 15:20:36 -0700662 Generally, if you don't have a battery in your machine, there isn't
663 much point in using this driver and you should say N. If you get
664 random kernel OOPSes or reboots that don't seem to be related to
665 anything, try disabling/enabling this option (or disabling/enabling
666 APM in your BIOS).
