+	  You can say N here if you don't intend to connect your Linux box to
+	  any other computer at all or if all your connections will be over a
+	  telephone line with a modem either via UUCP (UUCP is a protocol to
+	  forward mail and news between unix hosts over telephone lines; read
+	  the UUCP-HOWTO, available from
+	  <http://www.linuxdoc.org/docs.html#howto>) or dialing up a shell
+	  account or a BBS, even using term (term is a program which gives you
+	  almost full Internet connectivity if you have a regular dial up
+	  shell account on some Internet connected Unix computer. Read
+	  <http://www.bart.nl/~patrickr/term-howto/Term-HOWTO.html>).
+
+	  You'll have to say Y if your computer contains a network card that
+	  you want to use under Linux (make sure you know its name because you
+	  will be asked for it and read the Ethernet-HOWTO (especially if you
+	  plan to use more than one network card under Linux)) or if you want
+	  to use SLIP (Serial Line Internet Protocol is the protocol used to
+	  send Internet traffic over telephone lines or null modem cables) or
+	  CSLIP (compressed SLIP) or PPP (Point to Point Protocol, a better
+	  and newer replacement for SLIP) or PLIP (Parallel Line Internet
+	  Protocol is mainly used to create a mini network by connecting the
+	  parallel ports of two local machines) or AX.25/KISS (protocol for
+	  sending Internet traffic over amateur radio links).
+
+	  Make sure to read the NET-3-HOWTO. Eventually, you will have to read
+	  Olaf Kirch's excellent and free book "Network Administrator's
+	  Guide", to be found in <http://www.linuxdoc.org/docs.html#guide>. If
+	  unsure, say Y.

+config VT
+	bool "Virtual terminal"
+	requires INPUT=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"
+	depends on VT
+	---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 && !S390 && !UM
+	default y
+
+config SH_SCI
+	tristate "Serial (SCI) support"
+	help
+	  Selecting this option will allow the Linux kernel to transfer data
+	  over SCI (Serial Communication Interface) and/or SCIF (Serial
+	  Communication Interface with FIFO) which are built into the Hitachi
+	  SuperH processor.  The option provides 1 to 3 (depending
+	  on the CPU model) standard Linux tty devices, /dev/ttySC[012]; one
+	  of these is normally used as the system console.
+
+	  If in doubt, press "y".
+
+config SERIAL_CONSOLE
+	bool "Support for console on serial port"
+	depends on SERIAL=y || SH_SCI=y
+	---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.
+
+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.

+/* Core file format: The core file is written in such a way that gdb
+   can understand it and provide useful information to the user (under
+   linux we use the 'trad-core' bfd).  There are quite a number of
+   obstacles to being able to view the contents of the floating point
+   registers, and until these are solved you will not be able to view the
+   contents of them.  Actually, you can read in the core file and look at
+   the contents of the user struct to find out what the floating point
+   registers contain.
+   The actual file contents are as follows:
+   UPAGE: 1 page consisting of a user struct that tells gdb what is present
+   in the file.  Directly after this is a copy of the task_struct, which
+   is currently not used by gdb, but it may come in useful at some point.
+   All of the registers are stored as part of the upage.  The upage should
+   always be only one page.
+   DATA: The data area is stored.  We use current->end_text to
+   current->brk to pick up all of the user variables, plus any memory
+   that may have been malloced.  No attempt is made to determine if a page
+   is demand-zero or if a page is totally unused, we just cover the entire
+   range.  All of the addresses are rounded in such a way that an integral
+   number of pages is written.
+   STACK: We need the stack information in order to get a meaningful
+   backtrace.  We need to write the data from (esp) to
+   current->start_stack, so we round each of these off in order to be able
+   to write an integer number of pages.
+   The minimum core file size is 3 pages, or 12288 bytes.
