config EISA
	bool
	---help---
	  The Extended Industry Standard Architecture (EISA) bus was
	  developed as an open alternative to the IBM MicroChannel bus.

	  The EISA bus provided some of the features of the IBM MicroChannel
	  bus while maintaining backward compatibility with cards made for
	  the older ISA bus.  The EISA bus saw limited use between 1988 and
	  1995 when it was made obsolete by the PCI bus.

	  Say Y here if you are building a kernel for an EISA-based machine.

	  Otherwise, say N.

config MCA
	bool
	help
	  MicroChannel Architecture is found in some IBM PS/2 machines and
	  laptops.  It is a bus system similar to PCI or ISA. See
	  <file:Documentation/mca.txt> (and especially the web page given
	  there) before attempting to build an MCA bus kernel.

config PCMCIA
	tristate
	---help---
	  Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
	  computer.  These are credit-card size devices such as network cards,
	  modems or hard drives often used with laptops computers.  There are
	  actually two varieties of these cards: the older 16 bit PCMCIA cards
	  and the newer 32 bit CardBus cards.  If you want to use CardBus
	  cards, you need to say Y here and also to "CardBus support" below.

	  To use your PC-cards, you will need supporting software from David
	  Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
	  for location).  Please also read the PCMCIA-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>.

	  To compile this driver as modules, choose M here: the
	  modules will be called pcmcia_core and ds.

config SUN3
	bool "Sun3 support"
	select M68020
	select MMU_SUN3 if MMU
	help
	  This option enables support for the Sun 3 series of workstations
	  (3/50, 3/60, 3/1xx, 3/2xx systems). Enabling this option requires
	  that all other hardware types must be disabled, as Sun 3 kernels
	  are incompatible with all other m68k targets (including Sun 3x!).

	  If you don't want to compile a kernel exclusively for a Sun 3, say N.

config AMIGA
	bool "Amiga support"
	depends on !MMU_SUN3
	help
	  This option enables support for the Amiga series of computers. If
	  you plan to use this kernel on an Amiga, say Y here and browse the
	  material available in <file:Documentation/m68k>; otherwise say N.

config ATARI
	bool "Atari support"
	depends on !MMU_SUN3
	help
	  This option enables support for the 68000-based Atari series of
	  computers (including the TT, Falcon and Medusa). If you plan to use
	  this kernel on an Atari, say Y here and browse the material
	  available in <file:Documentation/m68k>; otherwise say N.

config HADES
	bool "Hades support"
	depends on ATARI && BROKEN
	help
	  This option enables support for the Hades Atari clone. If you plan
	  to use this kernel on a Hades, say Y here; otherwise say N.

config PCI
	bool
	depends on HADES
	default y
	help
	  Find out whether you have a PCI motherboard. PCI is the name of a
	  bus system, i.e. the way the CPU talks to the other stuff inside
	  your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
	  VESA. If you have PCI, say Y, otherwise N.

config MAC
	bool "Macintosh support"
	depends on !MMU_SUN3
	help
	  This option enables support for the Apple Macintosh series of
	  computers (yes, there is experimental support now, at least for part
	  of the series).

	  Say N unless you're willing to code the remaining necessary support.

	  Domain workstation such as the DN3500.

config VME
	bool "VME (Motorola and BVM) support"
	depends on !MMU_SUN3
	help
	  Say Y here if you want to build a kernel for a 680x0 based VME
	  board.  Boards currently supported include Motorola boards MVME147,
	  MVME162, MVME166, MVME167, MVME172, and MVME177.  BVME4000 and
	  BVME6000 boards from BVM Ltd are also supported.

config MVME147
	bool "MVME147 support"
	depends on VME
	help
	  Say Y to include support for early Motorola VME boards.  This will
	  build a kernel which can run on MVME147 single-board computers.  If
	  you select this option you will have to select the appropriate
	  drivers for SCSI, Ethernet and serial ports later on.

config MVME16x
	bool "MVME162, 166 and 167 support"
	depends on VME
	help
	  Say Y to include support for Motorola VME boards.  This will build a
	  kernel which can run on MVME162, MVME166, MVME167, MVME172, and
	  MVME177 boards.  If you select this option you will have to select
	  the appropriate drivers for SCSI, Ethernet and serial ports later
	  on.

config BVME6000
	bool "BVME4000 and BVME6000 support"
	depends on VME
	help
	  Say Y to include support for VME boards from BVM Ltd.  This will
	  build a kernel which can run on BVME4000 and BVME6000 boards.  If
	  you select this option you will have to select the appropriate

config HP300
	bool "HP9000/300 and HP9000/400 support"
	depends on !MMU_SUN3
	help
	  This option enables support for the HP9000/300 and HP9000/400 series
	  of workstations. Support for these machines is still somewhat
	  experimental. If you plan to try to use the kernel on such a machine
	  say Y here.
	  Everybody else says N.

config DIO
	bool "DIO bus support"
	depends on HP300
	default y
	help
	  Say Y here to enable support for the "DIO" expansion bus used in
	  HP300 machines. If you are using such a system you almost certainly
	  want this.

config SUN3X
	bool "Sun3x support"
	depends on !MMU_SUN3
	select M68030
	help
	  This option enables support for the Sun 3x series of workstations.
	  Be warned that this support is very experimental.
	  Note that Sun 3x kernels are not compatible with Sun 3 hardware.
	  General Linux information on the Sun 3x series (now discontinued)
	  is at <http://www.angelfire.com/ca2/tech68k/sun3.html>.

	  If you don't want to compile a kernel for a Sun 3x, say N.

config Q40
	bool "Q40/Q60 support"
	depends on !MMU_SUN3
	help
	  The Q40 is a Motorola 68040-based successor to the Sinclair QL
	  manufactured in Germany.  There is an official Q40 home page at
	  <http://www.q40.de/>.  This option enables support for the Q40 and
	  Q60. Select your CPU below.  For 68LC060 don't forget to enable FPU
	  emulation.

config M68020
	bool "68020 support"
	help
	  If you anticipate running this kernel on a computer with a MC68020
	  processor, say Y. Otherwise, say N. Note that the 68020 requires a
	  68851 MMU (Memory Management Unit) to run Linux/m68k, except on the
	  Sun 3, which provides its own version.

config M68030
	bool "68030 support"
	depends on !MMU_SUN3
	help
	  If you anticipate running this kernel on a computer with a MC68030
	  processor, say Y. Otherwise, say N. Note that a MC68EC030 will not
	  work, as it does not include an MMU (Memory Management Unit).

config M68040
	bool "68040 support"
	depends on !MMU_SUN3
	help
	  If you anticipate running this kernel on a computer with a MC68LC040
	  or MC68040 processor, say Y. Otherwise, say N. Note that an
	  MC68EC040 will not work, as it does not include an MMU (Memory
	  Management Unit).

config MMU_SUN3
	bool

config M68KFPU_EMU
	bool "Math emulation support (EXPERIMENTAL)"
	depends on EXPERIMENTAL
	help
	  At some point in the future, this will cause floating-point math
	  instructions to be emulated by the kernel on machines that lack a
	  floating-point math coprocessor.  Thrill-seekers and chronically
	  sleep-deprived psychotic hacker types can say Y now, everyone else
	  should probably wait a while.

config M68KFPU_EMU_EXTRAPREC
	bool "Math emulation extra precision"
	depends on M68KFPU_EMU
	help
	  The fpu uses normally a few bit more during calculations for
	  correct rounding, the emulator can (often) do the same but this
	  extra calculation can cost quite some time, so you can disable
	  it here. The emulator will then "only" calculate with a 64 bit
	  mantissa and round slightly incorrect, what is more then enough
	  for normal usage.

config M68KFPU_EMU_ONLY
	bool "Math emulation only kernel"
	depends on M68KFPU_EMU
	help
	  This option prevents any floating-point instructions from being
	  compiled into the kernel, thereby the kernel doesn't save any
	  floating point context anymore during task switches, so this
	  kernel will only be usable on machines without a floating-point
	  math coprocessor. This makes the kernel a bit faster as no tests
	  needs to be executed whether a floating-point instruction in the
	  kernel should be executed or not.

config ADVANCED
	bool "Advanced configuration options"
	---help---
	  This gives you access to some advanced options for the CPU. The
	  defaults should be fine for most users, but these options may make
	  it possible for you to improve performance somewhat if you know what
	  you are doing.

	  Note that the answer to this question won't directly affect the
	  kernel: saying N will just cause the configurator to skip all
	  the questions about these options.

	  Most users should say N to this question.

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

config SINGLE_MEMORY_CHUNK
	bool "Use one physical chunk of memory only" if ADVANCED && !SUN3
	default y if SUN3
	select NEED_MULTIPLE_NODES
	help
	  Ignore all but the first contiguous chunk of physical memory for VM
	  purposes.  This will save a few bytes kernel size and may speed up
	  some operations.  Say N if not sure.

config 060_WRITETHROUGH
	bool "Use write-through caching for 68060 supervisor accesses"
	depends on ADVANCED && M68060
	---help---
	  The 68060 generally uses copyback caching of recently accessed data.
	  Copyback caching means that memory writes will be held in an on-chip
	  cache and only written back to memory some time later.  Saying Y
	  here will force supervisor (kernel) accesses to use writethrough
	  caching.  Writethrough caching means that data is written to memory
	  straight away, so that cache and memory data always agree.
	  Writethrough caching is less efficient, but is needed for some
	  drivers on 68060 based systems where the 68060 bus snooping signal
	  is hardwired on.  The 53c710 SCSI driver is known to suffer from
	  this problem.

	depends on AMIGA
	help
	  This enables support for the Zorro bus in the Amiga. If you have
	  expansion cards in your Amiga that conform to the Amiga
	  AutoConfig(tm) specification, say Y, otherwise N. Note that even
	  expansion cards that do not fit in the Zorro slots but fit in e.g.
	  the CPU slot may fall in this category, so you have to say Y to let
	  Linux use these.

config AMIGA_PCMCIA
	bool "Amiga 1200/600 PCMCIA support (EXPERIMENTAL)"
	depends on AMIGA && EXPERIMENTAL
	help
	  Include support in the kernel for pcmcia on Amiga 1200 and Amiga
	  600. If you intend to use pcmcia cards say Y; otherwise say N.

	help
	  Use the power-on LED on your machine as a load meter.  The exact
	  behavior is platform-dependent, but normally the flash frequency is
	  a hyperbolic function of the 5-minute load average.

# We have a dedicated heartbeat LED. :-)
config PROC_HARDWARE
	bool "/proc/hardware support"
	help
	  Say Y here to support the /proc/hardware file, which gives you
	  access to information about the machine you're running on,

	  and memory size.

config ISA

	  Find out whether you have ISA slots on your motherboard.  ISA is the
	  name of a bus system, i.e. the way the CPU talks to the other stuff
	  inside your box.  Other bus systems are PCI, EISA, MicroChannel
	  (MCA) or VESA.  ISA is an older system, now being displaced by PCI;
