61 bus while maintaining backward compatibility with cards made for
62 the older ISA bus. The EISA bus saw limited use between 1988 and
63 1995 when it was made obsolete by the PCI bus.

320 This option prevents any floating-point instructions from being
321 compiled into the kernel, thereby the kernel doesn't save any
322 floating point context anymore during task switches, so this
323 kernel will only be usable on machines without a floating-point

348 workaround of disabling interrupts, it can conflict with DMA
349 ( = direct memory access) on many Amiga systems, and it is also said
350 to destabilize other machines. It is very likely that this will
351 cause serious problems on any Amiga or Atari Medusa if set. The only
352 configuration where it should work are 68030-based Ataris, where it

368 ---help---
369 The 68060 generally uses copyback caching of recently accessed data.
370 Copyback caching means that memory writes will be held in an on-chip
371 cache and only written back to memory some time later. Saying Y
372 here will force supervisor (kernel) accesses to use writethrough
373 caching. Writethrough caching means that data is written to memory
374 straight away, so that cache and memory data always agree.
375 Writethrough caching is less efficient, but is needed for some
376 drivers on 68060 based systems where the 68060 bus snooping signal
377 is hardwired on. The 53c710 SCSI driver is known to suffer from
378 this problem.

576 This provides support for sending raw ADB keycodes to console
577 devices. This is the default up to 2.4.0, but in future this may be
578 phased out in favor of generic Linux keycodes. If you say Y here,
579 you can dynamically switch via the
580 /proc/sys/dev/mac_hid/keyboard_sends_linux_keycodes
581 sysctl and with the "keyboard_sends_linux_keycodes=" kernel
582 argument.

590 This option allows you to use an ADB keyboard attached to your
591 machine. Note that this disables any other (ie. PS/2) keyboard
592 support, even if your machine is physically capable of using both at
593 the same time.
594
595 If you use an ADB keyboard (4 pin connector), say Y here.
596 If you use a PS/2 keyboard (6 pin connector), say N here.

649 ---help---
650 If you say Y here, it will be possible to use a serial port as the
651 system console (the system console is the device which receives all
652 kernel messages and warnings and which allows logins in single user
653 mode). This could be useful if some terminal or printer is connected
654 to that serial port.
655
656 Even if you say Y here, the currently visible virtual console
657 (/dev/tty0) will still be used as the system console by default, but
658 you can alter that using a kernel command line option such as
659 "console=ttyS1". (Try "man bootparam" or see the documentation of
660 your boot loader (lilo or loadlin) about how to pass options to the
661 kernel at boot time.)
662
663 If you don't have a VGA card installed and you say Y here, the
664 kernel will automatically use the first serial line, /dev/ttyS0, as
665 system console.
666
667 If unsure, say N.
