	  This lets you select the page size of the kernel.

	  8KB and 64KB work quite well, since Sparc ELF sections
	  provide for up to 64KB alignment.

	  Therefore, 512KB and 4MB are for expert hackers only.

config BBC_I2C
	tristate "UltraSPARC-III bootbus i2c controller driver"
	depends on PCI
	help
	  The BBC devices on the UltraSPARC III have two I2C controllers.  The
	  first I2C controller connects mainly to configuration PROMs (NVRAM,
	  CPU configuration, DIMM types, etc.).  The second I2C controller
	  connects to environmental control devices such as fans and
	  temperature sensors.  The second controller also connects to the
	  smartcard reader, if present.  Say Y to enable support for these.

config VT
	bool "Virtual terminal" if EMBEDDED
	select INPUT
	default y
	---help---
	  If you say Y here, you will get support for terminal devices with
	  display and keyboard devices. These are called "virtual" because you
	  can run several virtual terminals (also called virtual consoles) on
	  one physical terminal. This is rather useful, for example one
	  virtual terminal can collect system messages and warnings, another
	  one can be used for a text-mode user session, and a third could run
	  an X session, all in parallel. Switching between virtual terminals
	  is done with certain key combinations, usually Alt-<function key>.

	  The setterm command ("man setterm") can be used to change the
	  properties (such as colors or beeping) of a virtual terminal. The
	  man page console_codes(4) ("man console_codes") contains the special
	  character sequences that can be used to change those properties
	  directly. The fonts used on virtual terminals can be changed with
	  the setfont ("man setfont") command and the key bindings are defined
	  with the loadkeys ("man loadkeys") command.

	  You need at least one virtual terminal device in order to make use
	  of your keyboard and monitor. Therefore, only people configuring an
	  embedded system would want to say N here in order to save some
	  memory; the only way to log into such a system is then via a serial
	  or network connection.

	  If unsure, say Y, or else you won't be able to do much with your new
	  shiny Linux system :-)

config VT_CONSOLE
	bool "Support for console on virtual terminal" if EMBEDDED
	depends on VT
	default y
	---help---
	  The system console is the device which receives all kernel messages
	  and warnings and which allows logins in single user mode. If you
	  answer Y here, a virtual terminal (the device used to interact with
	  a physical terminal) can be used as system console. This is the most
	  common mode of operations, so you should say Y here unless you want
	  the kernel messages be output only to a serial port (in which case
	  you should say Y to "Console on serial port", below).

	  If you do say Y here, by default the currently visible virtual
	  terminal (/dev/tty0) will be used as system console. You can change
	  that with a kernel command line option such as "console=tty3" which
	  would use the third virtual terminal as system console. (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 unsure, say Y.

config HW_CONSOLE
	bool
	depends on VT
	default y

config SMP
	bool "Symmetric multi-processing support"
	---help---
	  This enables support for systems with more than one CPU. If you have
	  a system with only one CPU, say N. If you have a system with more than
	  one CPU, say Y.

	  If you say N here, the kernel will run on single and multiprocessor
	  machines, but will use only one CPU of a multiprocessor machine. If
	  you say Y here, the kernel will run on many, but not all,
	  singleprocessor machines. On a singleprocessor machine, the kernel
	  will run faster if you say N here.

	  People using multiprocessor machines who say Y here should also say
	  Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
	  Management" code will be disabled if you say Y here.

	  See also the <file:Documentation/smp.txt>,
	  <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO available at
	  <http://www.tldp.org/docs.html#howto>.

	  If you don't know what to do here, say N.

config PREEMPT
	bool "Preemptible Kernel"
	help
	  This option reduces the latency of the kernel when reacting to
	  real-time or interactive events by allowing a low priority process to
	  be preempted even if it is in kernel mode executing a system call.
	  This allows applications to run more reliably even when the system is
	  under load.

	  Say Y here if you are building a kernel for a desktop, embedded
	  or real-time system.  Say N if you are unsure.

config ISA
	bool
	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 ISAPNP
	bool
	help
	  Say Y here if you would like support for ISA Plug and Play devices.
	  Some information is in <file:Documentation/isapnp.txt>.

	  To compile this driver as a module, choose M here: the
	  module will be called isapnp.

	  If unsure, say Y.

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 PCI
	bool "PCI support"
	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 PCI_DOMAINS
	bool
	default PCI

config RTC
	tristate
	depends on PCI
	default y
	---help---
	  If you say Y here and create a character special file /dev/rtc with
	  major number 10 and minor number 135 using mknod ("man mknod"), you
	  will get access to the real time clock (or hardware clock) built
	  into your computer.

	  Every PC has such a clock built in. It can be used to generate
	  signals from as low as 1Hz up to 8192Hz, and can also be used
	  as a 24 hour alarm. It reports status information via the file
	  /proc/driver/rtc and its behaviour is set by various ioctls on
	  /dev/rtc.

	  If you run Linux on a multiprocessor machine and said Y to
	  "Symmetric Multi Processing" above, you should say Y here to read
	  and set the RTC in an SMP compatible fashion.

	  If you think you have a use for such a device (such as periodic data
	  sampling), then say Y here, and read <file:Documentation/rtc.txt>
	  for details.

	  To compile this driver as a module, choose M here: the
	  module will be called rtc.

source "drivers/pci/Kconfig"

config SUN_OPENPROMFS
	tristate "Openprom tree appears in /proc/openprom"
	help
	  If you say Y, the OpenPROM device tree will be available as a
	  virtual file system, which you can mount to /proc/openprom by "mount
	  -t openpromfs none /proc/openprom".

	  To compile the /proc/openprom support as a module, choose M here: the
	  module will be called openpromfs.  If unsure, choose M.

config SPARC32_COMPAT
	bool "Kernel support for Linux/Sparc 32bit binary compatibility"

	depends on SPARC32_COMPAT
	help
	  This allows you to run 32-bit a.out format binaries on your Ultra.
	  If you want to run SunOS binaries (see SunOS binary emulation below)
	  or other a.out binaries, say Y. If unsure, say N.

source "fs/Kconfig.binfmt"

config SUNOS_EMUL
	bool "SunOS binary emulation"
	depends on BINFMT_AOUT32
	help
	  This allows you to run most SunOS binaries.  If you want to do this,
	  say Y here and place appropriate files in /usr/gnemul/sunos. See
	  <http://www.ultralinux.org/faq.html> for more information.  If you
	  want to run SunOS binaries on an Ultra you must also say Y to
	  "Kernel support for 32-bit a.out binaries" above.

config SOLARIS_EMUL
	tristate "Solaris binary emulation (EXPERIMENTAL)"
	depends on SPARC32_COMPAT && EXPERIMENTAL
	help
	  This is experimental code which will enable you to run (many)
	  Solaris binaries on your SPARC Linux machine.

	  To compile this code as a module, choose M here: the
	  module will be called solaris.

source "drivers/parport/Kconfig"

config PRINTER
	tristate "Parallel printer support"
	depends on PARPORT
	---help---
	  If you intend to attach a printer to the parallel port of your Linux
	  box (as opposed to using a serial printer; if the connector at the
	  printer has 9 or 25 holes ["female"], then it's serial), say Y.
	  Also read the Printing-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>.

	  It is possible to share one parallel port among several devices
	  (e.g. printer and ZIP drive) and it is safe to compile the
	  corresponding drivers into the kernel.
	  To compile this driver as a module, choose M here and read
	  <file:Documentation/parport.txt>.  The module will be called lp.

	  If you have several parallel ports, you can specify which ports to
	  use with the "lp" kernel command line option.  (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.)  The syntax of the
	  "lp" command line option can be found in <file:drivers/char/lp.c>.

	  If you have more than 8 printers, you need to increase the LP_NO
	  macro in lp.c and the PARPORT_MAX macro in parport.h.

config ENVCTRL
	tristate "SUNW, envctrl support"
	depends on PCI
	help
	  Kernel support for temperature and fan monitoring on Sun SME
	  machines.

	  To compile this driver as a module, choose M here: the
	  module will be called envctrl.

config DISPLAY7SEG
	tristate "7-Segment Display support"
	depends on PCI
	---help---
	  This is the driver for the 7-segment display and LED present on
	  Sun Microsystems CompactPCI models CP1400 and CP1500.

	  To compile this driver as a module, choose M here: the
	  module will be called display7seg.

	  If you do not have a CompactPCI model CP1400 or CP1500, or
	  another UltraSPARC-IIi-cEngine boardset with a 7-segment display,
	  you should say N to this option.

config CMDLINE_BOOL
	bool "Default bootloader kernel arguments"

config CMDLINE
	string "Initial kernel command string"
	depends on CMDLINE_BOOL
	default "console=ttyS0,9600 root=/dev/sda1"
	help
	  Say Y here if you want to be able to pass default arguments to
	  the kernel. This will be overridden by the bootloader, if you
	  use one (such as SILO). This is most useful if you want to boot
	  a kernel from TFTP, and want default options to be available
	  with having them passed on the command line.

	  NOTE: This option WILL override the PROM bootargs setting!

config UNIX98_PTYS
	bool "Unix98 PTY support"
	---help---
	  A pseudo terminal (PTY) is a software device consisting of two
	  halves: a master and a slave. The slave device behaves identical to
	  a physical terminal; the master device is used by a process to
	  read data from and write data to the slave, thereby emulating a
	  terminal. Typical programs for the master side are telnet servers
	  and xterms.

	  Linux has traditionally used the BSD-like names /dev/ptyxx for
	  masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
	  has a number of problems. The GNU C library glibc 2.1 and later,
	  however, supports the Unix98 naming standard: in order to acquire a
	  pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
	  terminal is then made available to the process and the pseudo
	  terminal slave can be accessed as /dev/pts/<number>. What was
	  traditionally /dev/ttyp2 will then be /dev/pts/2, for example.

	  The entries in /dev/pts/ are created on the fly by a virtual
	  file system; therefore, if you say Y here you should say Y to
	  "/dev/pts file system for Unix98 PTYs" as well.

	  If you want to say Y here, you need to have the C library glibc 2.1
	  or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
	  Read the instructions in <file:Documentation/Changes> pertaining to
	  pseudo terminals. It's safe to say N.

	  The maximum number of Unix98 PTYs that can be used at any one time.
	  The default is 256, and should be enough for desktop systems. Server
	  machines which support incoming telnet/rlogin/ssh connections and/or
	  serve several X terminals may want to increase this: every incoming
	  connection and every xterm uses up one PTY.

	  When not in use, each additional set of 256 PTYs occupy
	  approximately 8 KB of kernel memory on 32-bit architectures.
