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.

557 Say Y to include the NWFPE floating point emulator in the kernel.
558 This is necessary to run most binaries. Linux does not currently
559 support floating point hardware so you need to say Y here even if
560 your machine has an FPA or floating point co-processor podule.

569 Say Y to include 80-bit support in the kernel floating-point
570 emulator. Otherwise, only 32 and 64-bit support is compiled in.
571 Note that gcc does not generate 80-bit operations by default,
572 so in most cases this option only enlarges the size of the
573 floating point emulator without any good reason.

581 Say Y here to include the FAST floating point emulator in the kernel.
582 This is an experimental much faster emulator which now also has full
583 precision for the mantissa. It does not support any exceptions.
584 It is very simple, and approximately 3-6 times faster than NWFPE.
585
586 It should be sufficient for most programs. It may be not suitable
587 for scientific calculations, but you have to check this for yourself.
588 If you do not feel you need a faster FP emulation you should better
589 choose NWFPE.

625 "Power Management" means that parts of your computer are shut
626 off or put into a power conserving "sleep" mode if they are not
627 being used. There are two competing standards for doing this: APM
628 and ACPI. If you want to use either one, say Y here and then also
629 to the requisite support below.
630
631 Power Management is most important for battery powered laptop
632 computers; if you have a laptop, check out the Linux Laptop home
633 page on the WWW at <http://www.linux-on-laptops.com/> or
634 Tuxmobil - Linux on Mobile Computers at <http://www.tuxmobil.org/>

640 depends on PM
641 ---help---
642 APM is a BIOS specification for saving power using several different
643 techniques. This is mostly useful for battery powered laptops with
644 APM compliant BIOSes. If you say Y here, the system time will be
645 reset after a RESUME operation, the /proc/apm device will provide
646 battery status information, and user-space programs will receive
647 notification of APM "events" (e.g. battery status change).
648
Linus Torvalds1da177e2005-04-16 15:20:36 -0700649 In order to use APM, you will need supporting software. For location
650 and more information, read <file:Documentation/pm.txt> and the
651 Battery Powered Linux mini-HOWTO, available from
652 <http://www.tldp.org/docs.html#howto>.
653
654 This driver does not spin down disk drives (see the hdparm(8)
655 manpage ("man 8 hdparm") for that), and it doesn't turn off
656 VESA-compliant "green" monitors.
657
Linus Torvalds1da177e2005-04-16 15:20:36 -0700658 Generally, if you don't have a battery in your machine, there isn't
659 much point in using this driver and you should say N. If you get
660 random kernel OOPSes or reboots that don't seem to be related to
661 anything, try disabling/enabling this option (or disabling/enabling
662 APM in your BIOS).
