	---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
	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

config SMP
	bool "Symmetric multi-processing support (does not work on sun4/sun4c)"

	---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

config SPARC32
	bool
	default y
	help
	  SPARC is a family of RISC microprocessors designed and marketed by
	  Sun Microsystems, incorporated.  They are very widely found in Sun
	  workstations and clones. This port covers the original 32-bit SPARC;
	  it is old and stable and usually considered one of the "big three"
	  along with the Intel and Alpha ports.  The UltraLinux project
	  maintains both the SPARC32 and SPARC64 ports; its web page is

config PCMCIA

	---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

config SERIAL_CONSOLE

	  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 (silo) about how to pass options to the kernel at
	  boot time.)

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

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.

config UNIX98_PTY_COUNT
	int "Maximum number of Unix98 PTYs in use (0-2048)"
	depends on UNIX98_PTYS
	default "256"
	help
	  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.

	315	help
	316	The maximum number of Unix98 PTYs that can be used at any one time.
	317	The default is 256, and should be enough for desktop systems. Server
	318	machines which support incoming telnet/rlogin/ssh connections and/or
	319	serve several X terminals may want to increase this: every incoming
	320	connection and every xterm uses up one PTY.
	321
	322	When not in use, each additional set of 256 PTYs occupy
	323	approximately 8 KB of kernel memory on 32-bit architectures.
