 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.

 	  The PCI-HOWTO, available from
 	  <http://www.tldp.org/docs.html#howto>, contains valuable
 	  information about which PCI hardware does work under Linux and which
 	  doesn't.

 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
 	  drivers for SCSI, Ethernet and serial ports later on.

 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.

 comment "Processor type"

 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).

 	default y

 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"
 	depends on ADVANCED && !SUN3
 	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.

 config ZORRO

 	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)"

 	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
 	bool

 	  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;

	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

	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

	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

	config SINGLE_MEMORY_CHUNK

	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.
