        ---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

           (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 

          for location).  Please also read the PCMCIA-HOWTO, available from

          .

config SUN3

          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 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

        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

          , contains valuable

          information about which PCI hardware does work under Linux and which

          doesn't.

          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

        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

          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

          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

          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.

          If unsure, say Y here.

          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 an ADB keyboard (4 pin connector), say Y here.

          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.
