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.

502 On some architectures (EBSA110 and CATS), there is currently no way
503 for the boot loader to pass arguments to the kernel. For these
504 architectures, you should supply some command-line options at build
505 time by entering them here. As a minimum, you should specify the
506 memory size and the root device (e.g., mem=64M root=/dev/nfs).

508config XIP_KERNEL
509 bool "Kernel Execute-In-Place from ROM"

511 help
512 Execute-In-Place allows the kernel to run from non-volatile storage
513 directly addressable by the CPU, such as NOR flash. This saves RAM
514 space since the text section of the kernel is not loaded from flash
515 to RAM. Read-write sections, such as the data section and stack,
516 are still copied to RAM. The XIP kernel is not compressed since
517 it has to run directly from flash, so it will take more space to
518 store it. The flash address used to link the kernel object files,
519 and for storing it, is configuration dependent. Therefore, if you
520 say Y here, you must know the proper physical address where to
521 store the kernel image depending on your own flash memory usage.
522
523 Also note that the make target becomes "make xipImage" rather than
524 "make zImage" or "make Image". The final kernel binary to put in
525 ROM memory will be arch/arm/boot/xipImage.

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

605 It is very simple, and approximately 3-6 times faster than NWFPE.
606
607 It should be sufficient for most programs. It may be not suitable
608 for scientific calculations, but you have to check this for yourself.

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

649 and ACPI. If you want to use either one, say Y here and then also

662 ---help---
663 APM is a BIOS specification for saving power using several different
664 techniques. This is mostly useful for battery powered laptops with
665 APM compliant BIOSes. If you say Y here, the system time will be
666 reset after a RESUME operation, the /proc/apm device will provide
667 battery status information, and user-space programs will receive
668 notification of APM "events" (e.g. battery status change).
669
Linus Torvalds1da177e2005-04-16 15:20:36 -0700670 In order to use APM, you will need supporting software. For location
671 and more information, read <file:Documentation/pm.txt> and the
672 Battery Powered Linux mini-HOWTO, available from
673 <http://www.tldp.org/docs.html#howto>.

675 This driver does not spin down disk drives (see the hdparm(8)
676 manpage ("man 8 hdparm") for that), and it doesn't turn off
677 VESA-compliant "green" monitors.
678
Linus Torvalds1da177e2005-04-16 15:20:36 -0700679 Generally, if you don't have a battery in your machine, there isn't
680 much point in using this driver and you should say N. If you get
681 random kernel OOPSes or reboots that don't seem to be related to
682 anything, try disabling/enabling this option (or disabling/enabling
683 APM in your BIOS).
