  55. The EISA bus provided some of the features of the IBM MicroChannel
  56. bus while maintaining backward compatibility with cards made for
  57. the older ISA bus. The EISA bus saw limited use between 1988 and

  76. cards, you need to say Y here and also to "CardBus support" below.
  77. To use your PC-cards, you will need supporting software from David
  78. Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
  79. for location). Please also read the PCMCIA-HOWTO, available from

  197. This option enables support for the Sun 3 series of workstations
  198. (3/50, 3/60, 3/1xx, 3/2xx systems). Enabling this option requires
  199. that all other hardware types must be disabled, as Sun 3 kernels
  200. are incompatible with all other m68k targets (including Sun 3x!).

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

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

  269. ---help---
  270. This gives you access to some advanced options for the CPU. The
  271. defaults should be fine for most users, but these options may make
  272. it possible for you to improve performance somewhat if you know what
  273. you are doing.
  274. Note that the answer to this question won't directly affect the
  275. kernel: saying N will just cause the configurator to skip all
  276. the questions about these options.
  277. Most users should say N to this question.
  278. config RMW_INSNS
  279. bool "Use read-modify-write instructions"
  280. depends on ADVANCED
  281. ---help---
  282. This allows to use certain instructions that work with indivisible
  283. read-modify-write bus cycles. While this is faster than the
  284. workaround of disabling interrupts, it can conflict with DMA
  285. ( = direct memory access) on many Amiga systems, and it is also said
  286. to destabilize other machines. It is very likely that this will
  287. cause serious problems on any Amiga or Atari Medusa if set. The only
  288. configuration where it should work are 68030-based Ataris, where it
  289. apparently improves performance. But you've been warned! Unless you
  290. really know what you are doing, say N. Try Y only if you're quite

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

  491. If you say Y here, it will be possible to use a serial port as the
  492. system console (the system console is the device which receives all
  493. kernel messages and warnings and which allows logins in single user
  494. mode). This could be useful if some terminal or printer is connected
  495. to that serial port.
  496. Even if you say Y here, the currently visible virtual console
  497. (/dev/tty0) will still be used as the system console by default, but
  498. you can alter that using a kernel command line option such as
  499. "console=ttyS1". (Try "man bootparam" or see the documentation of
  500. your boot loader (lilo or loadlin) about how to pass options to the
  501. kernel at boot time.)
  502. If you don't have a VGA card installed and you say Y here, the
  503. kernel will automatically use the first serial line, /dev/ttyS0, as
  504. system console.
  505. If unsure, say N.
