68 The Extended Industry Standard Architecture (EISA) bus was
69 developed as an open alternative to the IBM MicroChannel bus.
71 The EISA bus provided some of the features of the IBM MicroChannel
72 bus while maintaining backward compatibility with cards made for
73 the older ISA bus. The EISA bus saw limited use between 1988 and
74 1995 when it was made obsolete by the PCI bus.
76 Say Y here if you are building a kernel for an EISA-based machine.
83 MicroChannel Architecture is found in some IBM PS/2 machines and
84 laptops. It is a bus system similar to PCI or ISA. See
85 <file:Documentation/mca.txt> (and especially the web page given
86 there) before attempting to build an MCA bus kernel.
91 Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
92 computer. These are credit-card size devices such as network cards,
93 modems or hard drives often used with laptops computers. There are
94 actually two varieties of these cards: the older 16 bit PCMCIA cards
95 and the newer 32 bit CardBus cards. If you want to use CardBus
96 cards, you need to say Y here and also to "CardBus support" below.
98 To use your PC-cards, you will need supporting software from David
99 Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
100 for location). Please also read the PCMCIA-HOWTO, available from
101 <http://www.tldp.org/docs.html#howto>.
103 To compile this driver as modules, choose M here: the
104 modules will be called pcmcia_core and ds.

110 This option enables support for the Amiga series of computers. If
111 you plan to use this kernel on an Amiga, say Y here and browse the
112 material available in <file:Documentation/m68k>; otherwise say N.
116 select MMU_MOTOROLA if MMU
118 This option enables support for the 68000-based Atari series of
119 computers (including the TT, Falcon and Medusa). If you plan to use

149 Domain workstation such as the DN3500.

153 select MMU_MOTOROLA if MMU
155 Say Y here if you want to build a kernel for a 680x0 based VME
156 board. Boards currently supported include Motorola boards MVME147,
157 MVME162, MVME166, MVME167, MVME172, and MVME177. BVME4000 and
158 BVME6000 boards from BVM Ltd are also supported.
161 bool "MVME147 support"
164 Say Y to include support for early Motorola VME boards. This will
165 build a kernel which can run on MVME147 single-board computers. If
166 you select this option you will have to select the appropriate
167 drivers for SCSI, Ethernet and serial ports later on.
170 bool "MVME162, 166 and 167 support"
173 Say Y to include support for Motorola VME boards. This will build a
174 kernel which can run on MVME162, MVME166, MVME167, MVME172, and
175 MVME177 boards. If you select this option you will have to select
176 the appropriate drivers for SCSI, Ethernet and serial ports later
180 bool "BVME4000 and BVME6000 support"
183 Say Y to include support for VME boards from BVM Ltd. This will
184 build a kernel which can run on BVME4000 and BVME6000 boards. If
185 you select this option you will have to select the appropriate

192 This option enables support for the HP9000/300 and HP9000/400 series
193 of workstations. Support for these machines is still somewhat
194 experimental. If you plan to try to use the kernel on such a machine

236 This option enables support for the Sun 3 series of workstations
237 (3/50, 3/60, 3/1xx, 3/2xx systems). Enabling this option requires
238 that all other hardware types must be disabled, as Sun 3 kernels
239 are incompatible with all other m68k targets (including Sun 3x!).
241 If you don't want to compile a kernel exclusively for a Sun 3, say N.

248 access to a disk image as /dev/hda.

274 comment "Processor type"
279 If you anticipate running this kernel on a computer with a MC68020
280 processor, say Y. Otherwise, say N. Note that the 68020 requires a
281 68851 MMU (Memory Management Unit) to run Linux/m68k, except on the
282 Sun 3, which provides its own version.
288 If you anticipate running this kernel on a computer with a MC68030

316 bool "Math emulation support (EXPERIMENTAL)"
317 depends on EXPERIMENTAL
319 At some point in the future, this will cause floating-point math
320 instructions to be emulated by the kernel on machines that lack a
321 floating-point math coprocessor. Thrill-seekers and chronically
322 sleep-deprived psychotic hacker types can say Y now, everyone else
323 should probably wait a while.
325 config M68KFPU_EMU_EXTRAPREC
326 bool "Math emulation extra precision"
327 depends on M68KFPU_EMU
329 The fpu uses normally a few bit more during calculations for
330 correct rounding, the emulator can (often) do the same but this
331 extra calculation can cost quite some time, so you can disable
332 it here. The emulator will then "only" calculate with a 64 bit
333 mantissa and round slightly incorrect, what is more than enough
336 config M68KFPU_EMU_ONLY
337 bool "Math emulation only kernel"
338 depends on M68KFPU_EMU
340 This option prevents any floating-point instructions from being
341 compiled into the kernel, thereby the kernel doesn't save any
342 floating point context anymore during task switches, so this
343 kernel will only be usable on machines without a floating-point
344 math coprocessor. This makes the kernel a bit faster as no tests
345 needs to be executed whether a floating-point instruction in the
346 kernel should be executed or not.
349 bool "Advanced configuration options"
351 This gives you access to some advanced options for the CPU. The
352 defaults should be fine for most users, but these options may make
353 it possible for you to improve performance somewhat if you know what
356 Note that the answer to this question won't directly affect the
357 kernel: saying N will just cause the configurator to skip all
358 the questions about these options.
360 Most users should say N to this question.
363 bool "Use read-modify-write instructions"
366 This allows to use certain instructions that work with indivisible
367 read-modify-write bus cycles. While this is faster than the
368 workaround of disabling interrupts, it can conflict with DMA
369 ( = direct memory access) on many Amiga systems, and it is also said
370 to destabilize other machines. It is very likely that this will
371 cause serious problems on any Amiga or Atari Medusa if set. The only
372 configuration where it should work are 68030-based Ataris, where it
373 apparently improves performance. But you've been warned! Unless you
374 really know what you are doing, say N. Try Y only if you're quite

378 bool "Use one physical chunk of memory only" if ADVANCED && !SUN3
380 select NEED_MULTIPLE_NODES
382 Ignore all but the first contiguous chunk of physical memory for VM
383 purposes. This will save a few bytes kernel size and may speed up
384 some operations. Say N if not sure.
386 config 060_WRITETHROUGH
387 bool "Use write-through caching for 68060 supervisor accesses"
388 depends on ADVANCED && M68060
390 The 68060 generally uses copyback caching of recently accessed data.
391 Copyback caching means that memory writes will be held in an on-chip
392 cache and only written back to memory some time later. Saying Y
393 here will force supervisor (kernel) accesses to use writethrough
394 caching. Writethrough caching means that data is written to memory
395 straight away, so that cache and memory data always agree.
396 Writethrough caching is less efficient, but is needed for some
397 drivers on 68060 based systems where the 68060 bus snooping signal
398 is hardwired on. The 53c710 SCSI driver is known to suffer from
