 	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
 	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

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

 	bool

 	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.
