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
bool "Amiga support"
select MMU_MOTOROLA if MMU
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"
select MMU_MOTOROLA if MMU
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 MAC
bool "Macintosh support"
select MMU_MOTOROLA if MMU
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"
select MMU_MOTOROLA if MMU
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"
select MMU_MOTOROLA if MMU
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"
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.
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"
select MMU_MOTOROLA if MMU
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 SUN3
bool "Sun3 support"
depends on !MMU_MOTOROLA
select MMU_SUN3 if MMU
select M68020
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.
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).

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.

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 STRAM_PROC

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

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.

Linux, say Y. The driver equally supports all kinds of MFP serial
ports and automatically detects whether Serial1 is available.
To compile this driver as a module, choose M here.
Note for Falcon users: You also have an MFP port, it's just not
wired to the outside... But you could use the port under Linux.

---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.
