-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 AMIGA

-
-config MVME147
- bool "MVME147 support"

- 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

- drivers for SCSI, Ethernet and serial ports later on.
-

- 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.

- depends on HP300
- default y
- help
- Say Y here to enable support for the "DIO" expansion bus used in

-
-config SUN3X
- bool "Sun3x support"
- select MMU_MOTOROLA if MMU
- 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.

- is at <http://www.angelfire.com/ca2/tech68k/sun3.html>.

- 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 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

- work, as it does not include an MMU (Memory Management Unit).
-
-config M68040

- depends on !MMU_SUN3

-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 than 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.

-config ZORRO
- bool "Amiga Zorro (AutoConfig) bus support"
- 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.

-config HEARTBEAT
- bool "Use power LED as a heartbeat" if AMIGA || APOLLO || ATARI || MAC ||Q40
- default y if !AMIGA && !APOLLO && !ATARI && !MAC && !Q40 && HP300
- 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,
- including the model, CPU, MMU, clock speed, BogoMIPS rating,
- and memory size.
-
-config ISA
- bool
- depends on Q40 || AMIGA_PCMCIA
- default y
- help
- 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;
- newer boards don't support it. If you have ISA, say Y, otherwise N.
