  48. The Extended Industry Standard Architecture (EISA) bus was
  49. developed as an open alternative to the IBM MicroChannel bus.
  50. The EISA bus provided some of the features of the IBM MicroChannel
  51. bus while maintaining backward compatibility with cards made for
  52. the older ISA bus. The EISA bus saw limited use between 1988 and
  53. 1995 when it was made obsolete by the PCI bus.

  66. Say Y here if you want to attach PCMCIA- or PC-cards to your Linux

  68. modems or hard drives often used with laptops computers. There are
  69. actually two varieties of these cards: the older 16 bit PCMCIA cards
  70. and the newer 32 bit CardBus cards. If you want to use CardBus
  71. cards, you need to say Y here and also to "CardBus support" below.
  72. To use your PC-cards, you will need supporting software from David
  73. Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>

  84. (3/50, 3/60, 3/1xx, 3/2xx systems). Enabling this option requires
  85. that all other hardware types must be disabled, as Sun 3 kernels

  115. bus system, i.e. the way the CPU talks to the other stuff inside
  116. your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
  117. VESA. If you have PCI, say Y, otherwise N.
  118. The PCI-HOWTO, available from

  183. of workstations. Support for these machines is still somewhat
  184. experimental. If you plan to try to use the kernel on such a machine

  263. The fpu uses normally a few bit more during calculations for
  264. correct rounding, the emulator can (often) do the same but this
  265. extra calculation can cost quite some time, so you can disable
  266. it here. The emulator will then "only" calculate with a 64 bit
  267. mantissa and round slightly incorrect, what is more then enough
  268. for normal usage.
  269. config M68KFPU_EMU_ONLY
  270. bool "Math emulation only kernel"
  271. depends on M68KFPU_EMU
  272. help
  273. This option prevents any floating-point instructions from being
  274. compiled into the kernel, thereby the kernel doesn't save any
  275. floating point context anymore during task switches, so this
  276. kernel will only be usable on machines without a floating-point
  277. math coprocessor. This makes the kernel a bit faster as no tests
  278. needs to be executed whether a floating-point instruction in the

  285. it possible for you to improve performance somewhat if you know what
  286. you are doing.
  287. Note that the answer to this question won't directly affect the
  288. kernel: saying N will just cause the configurator to skip all

  294. ---help---
  295. This allows to use certain instructions that work with indivisible
  296. read-modify-write bus cycles. While this is faster than the
  297. workaround of disabling interrupts, it can conflict with DMA
  298. ( = direct memory access) on many Amiga systems, and it is also said
  299. to destabilize other machines. It is very likely that this will
  300. cause serious problems on any Amiga or Atari Medusa if set. The only
  301. configuration where it should work are 68030-based Ataris, where it
  302. apparently improves performance. But you've been warned! Unless you

  316. ---help---
  317. The 68060 generally uses copyback caching of recently accessed data.
  318. Copyback caching means that memory writes will be held in an on-chip
  319. cache and only written back to memory some time later. Saying Y
  320. here will force supervisor (kernel) accesses to use writethrough
  321. caching. Writethrough caching means that data is written to memory
  322. straight away, so that cache and memory data always agree.
  323. Writethrough caching is less efficient, but is needed for some
  324. drivers on 68060 based systems where the 68060 bus snooping signal
  325. is hardwired on. The 53c710 SCSI driver is known to suffer from
