  29. The Extended Industry Standard Architecture (EISA) bus was
  30. developed as an open alternative to the IBM MicroChannel bus.
  31. The EISA bus provided some of the features of the IBM MicroChannel
  32. bus while maintaining backward compatibility with cards made for
  33. the older ISA bus. The EISA bus saw limited use between 1988 and
  34. 1995 when it was made obsolete by the PCI bus.

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

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

  64. This option enables support for the Sun 3 series of workstations
  65. (3/50, 3/60, 3/1xx, 3/2xx systems). Enabling this option requires
  66. that all other hardware types must be disabled, as Sun 3 kernels

  235. At some point in the future, this will cause floating-point math
  236. instructions to be emulated by the kernel on machines that lack a
  237. floating-point math coprocessor. Thrill-seekers and chronically
  238. sleep-deprived psychotic hacker types can say Y now, everyone else

  243. help
  244. The fpu uses normally a few bit more during calculations for
  245. correct rounding, the emulator can (often) do the same but this
  246. extra calculation can cost quite some time, so you can disable
  247. it here. The emulator will then "only" calculate with a 64 bit
  248. mantissa and round slightly incorrect, what is more then enough
  249. for normal usage.
  250. config M68KFPU_EMU_ONLY
  251. bool "Math emulation only kernel"
  252. depends on M68KFPU_EMU
  253. help
  254. This option prevents any floating-point instructions from being
  255. compiled into the kernel, thereby the kernel doesn't save any
  256. floating point context anymore during task switches, so this
  257. kernel will only be usable on machines without a floating-point
  258. math coprocessor. This makes the kernel a bit faster as no tests
  259. needs to be executed whether a floating-point instruction in the
  260. kernel should be executed or not.

  264. This gives you access to some advanced options for the CPU. The
  265. defaults should be fine for most users, but these options may make
  266. it possible for you to improve performance somewhat if you know what
  267. you are doing.
  268. Note that the answer to this question won't directly affect the
  269. kernel: saying N will just cause the configurator to skip all
  270. the questions about these options.

  272. config RMW_INSNS
  273. bool "Use read-modify-write instructions"
  274. depends on ADVANCED
  275. ---help---
  276. This allows to use certain instructions that work with indivisible
  277. read-modify-write bus cycles. While this is faster than the
  278. workaround of disabling interrupts, it can conflict with DMA
  279. ( = direct memory access) on many Amiga systems, and it is also said
  280. to destabilize other machines. It is very likely that this will
  281. cause serious problems on any Amiga or Atari Medusa if set. The only
  282. configuration where it should work are 68030-based Ataris, where it
  283. apparently improves performance. But you've been warned! Unless you
  284. really know what you are doing, say N. Try Y only if you're quite
  285. adventurous.

  289. help
  290. Ignore all but the first contiguous chunk of physical memory for VM

  295. depends on ADVANCED && M68060
  296. ---help---
  297. The 68060 generally uses copyback caching of recently accessed data.
  298. Copyback caching means that memory writes will be held in an on-chip
  299. cache and only written back to memory some time later. Saying Y
  300. here will force supervisor (kernel) accesses to use writethrough
  301. caching. Writethrough caching means that data is written to memory
  302. straight away, so that cache and memory data always agree.
  303. Writethrough caching is less efficient, but is needed for some
  304. drivers on 68060 based systems where the 68060 bus snooping signal
  305. is hardwired on. The 53c710 SCSI driver is known to suffer from
  306. this problem.

  522. If you say Y here, it will be possible to use a serial port as the
  523. system console (the system console is the device which receives all
  524. kernel messages and warnings and which allows logins in single user
  525. mode). This could be useful if some terminal or printer is connected
  526. to that serial port.
  527. Even if you say Y here, the currently visible virtual console
  528. (/dev/tty0) will still be used as the system console by default, but
  529. you can alter that using a kernel command line option such as
  530. "console=ttyS1". (Try "man bootparam" or see the documentation of
  531. your boot loader (lilo or loadlin) about how to pass options to the
  532. kernel at boot time.)
  533. If you don't have a VGA card installed and you say Y here, the
  534. kernel will automatically use the first serial line, /dev/ttyS0, as
  535. system console.
