config EISA

        ---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

          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

          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

          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.

        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.

        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.

        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 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.

          expansion cards that do not fit in the Zorro slots but fit in e.g.

          This provides support for sending raw ADB keycodes to console
          devices.  This is the default up to 2.4.0, but in future this may be
          phased out in favor of generic Linux keycodes.  If you say Y here,
          you can dynamically switch via the
          /proc/sys/dev/mac_hid/keyboard_sends_linux_keycodes
          sysctl and with the "keyboard_sends_linux_keycodes=" kernel
          argument.

          This option allows you to use an ADB keyboard attached to your
          machine. Note that this disables any other (ie. PS/2) keyboard
          support, even if your machine is physically capable of using both at
          the same time.

          If you use a PS/2 keyboard (6 pin connector), say N here.

        ---help---
          If you say Y here, it will be possible to use a serial port as the
          system console (the system console is the device which receives all
          kernel messages and warnings and which allows logins in single user
          mode). This could be useful if some terminal or printer is connected
          to that serial port.

          Even if you say Y here, the currently visible virtual console
          (/dev/tty0) will still be used as the system console by default, but
          you can alter that using a kernel command line option such as
          "console=ttyS1". (Try "man bootparam" or see the documentation of
          your boot loader (lilo or loadlin) about how to pass options to the
          kernel at boot time.)

          If you don't have a VGA card installed and you say Y here, the
          kernel will automatically use the first serial line, /dev/ttyS0, as
          system console.

          If unsure, say N.
