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
	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 STRAM_SWAP
	bool "Support for ST-RAM as swap space"
	depends on ATARI && BROKEN
	---help---
	  Some Atari 68k macines (including the 520STF and 1020STE) divide
	  their addressible memory into ST and TT sections.  The TT section
	  (up to 512MB) is the main memory; the ST section (up to 4MB) is
	  accessible to the built-in graphics board, runs slower, and is
	  present mainly for backward compatibility with older machines.

	  This enables support for using (parts of) ST-RAM as swap space,
	  instead of as normal system memory. This can first enhance system
	  performance if you have lots of alternate RAM (compared to the size
	  of ST-RAM), because executable code always will reside in faster
	  memory. ST-RAM will remain as ultra-fast swap space. On the other
	  hand, it allows much improved dynamic allocations of ST-RAM buffers
	  for device driver modules (e.g. floppy, ACSI, SLM printer, DMA
	  sound). The probability that such allocations at module load time
	  fail is drastically reduced.

config STRAM_PROC
	bool "ST-RAM statistics in /proc"
	depends on ATARI
	help
	  Say Y here to report ST-RAM usage statistics in /proc/stram.  See
	  the help for CONFIG_STRAM_SWAP for discussion of ST-RAM and its
	  uses.

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 || GG2
	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.

config ATARI_MFPSER
	tristate "Atari MFP serial support"
	depends on ATARI
	---help---
	  If you like to use the MFP serial ports ("Modem1", "Serial1") under
	  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.

config ATARI_SCC
	tristate "Atari SCC serial support"
	depends on ATARI
	---help---
	  If you have serial ports based on a Zilog SCC chip (Modem2, Serial2,
	  LAN) and like to use them under Linux, say Y. All built-in SCC's are
	  supported (TT, MegaSTE, Falcon), and also the ST-ESCC. If you have
	  two connectors for channel A (Serial2 and LAN), they are visible as
	  two separate devices.

	  To compile this driver as a module, choose M here.

config ATARI_SCC_DMA
	bool "Atari SCC serial DMA support"
	depends on ATARI_SCC
	help
	  This enables DMA support for receiving data on channel A of the SCC.
	  If you have a TT you may say Y here and read
	  drivers/char/atari_SCC.README. All other users should say N here,
	  because only the TT has SCC-DMA, even if your machine keeps claiming
	  so at boot time.

config ATARI_MIDI
	tristate "Atari MIDI serial support"
	depends on ATARI
	help
	  If you want to use your Atari's MIDI port in Linux, say Y.

	  To compile this driver as a module, choose M here.

config ATARI_DSP56K
	tristate "Atari DSP56k support (EXPERIMENTAL)"
	depends on ATARI && EXPERIMENTAL
	help
	  If you want to be able to use the DSP56001 in Falcons, say Y. This
	  driver is still experimental, and if you don't know what it is, or
	  if you don't have this processor, just say N.

	  To compile this driver as a module, choose M here.

config AMIGA_BUILTIN_SERIAL
	tristate "Amiga builtin serial support"
	depends on AMIGA
	help
	  If you want to use your Amiga's built-in serial port in Linux,
	  answer Y.

	  To compile this driver as a module, choose M here.

config WHIPPET_SERIAL
	tristate "Hisoft Whippet PCMCIA serial support"
	depends on AMIGA_PCMCIA
	help
	  HiSoft has a web page at <http://www.hisoft.co.uk/>, but there
	  is no listing for the Whippet in their Amiga section.

config MULTIFACE_III_TTY

config GVPIOEXT

	  Otherwise, say N.

config GVPIOEXT_LP
	tristate "GVP IO-Extender parallel printer support"
	depends on GVPIOEXT
	help
	  Say Y to enable driving a printer from the parallel port on your
	  GVP IO-Extender card, N otherwise.

config GVPIOEXT_PLIP
	tristate "GVP IO-Extender PLIP support"
	depends on GVPIOEXT

config MAC_ADBKEYCODES
	bool "Support for ADB raw keycodes"
	depends on INPUT_ADBHID
	help
	  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.

config ADB_KEYBOARD
	bool "Support for ADB keyboard (old driver)"
	depends on MAC && !INPUT_ADBHID
	help
	  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.

config HPDCA

	  This is the driver for the serial ports on the Motorola MVME147
	  boards.  Everyone using one of these boards should say Y here.

config SERIAL167
	bool "CD2401 support for MVME166/7 serial ports"
	depends on MVME16x && BROKEN

	  This is the driver for the serial ports on the Motorola MVME166,

	---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.
