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

  74. modems or hard drives often used with laptops computers. There are
  75. actually two varieties of these cards: the older 16 bit PCMCIA cards

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

  91. that all other hardware types must be disabled, as Sun 3 kernels

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

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

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

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

  380. Find out whether you have ISA slots on your motherboard. ISA is the
  381. name of a bus system, i.e. the way the CPU talks to the other stuff
  382. inside your box. Other bus systems are PCI, EISA, MicroChannel
  383. (MCA) or VESA. ISA is an older system, now being displaced by PCI;
  384. newer boards don't support it. If you have ISA, say Y, otherwise N.

  506. If you say Y here, it will be possible to use a serial port as the
  507. system console (the system console is the device which receives all
  508. kernel messages and warnings and which allows logins in single user
  509. mode). This could be useful if some terminal or printer is connected
  510. to that serial port.
  511. Even if you say Y here, the currently visible virtual console
  512. (/dev/tty0) will still be used as the system console by default, but
  513. you can alter that using a kernel command line option such as
  514. "console=ttyS1". (Try "man bootparam" or see the documentation of
  515. your boot loader (lilo or loadlin) about how to pass options to the
  516. kernel at boot time.)
  517. If you don't have a VGA card installed and you say Y here, the
  518. kernel will automatically use the first serial line, /dev/ttyS0, as
  519. system console.
  520. If unsure, say N.
