+config VT
+        bool "Virtual terminal" if EMBEDDED
+        select INPUT
+        default y if !VIOCONS
+        ---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 SERIAL_NONSTANDARD
+        bool "Non-standard serial port support"
+        ---help---
+          Say Y here if you have any non-standard serial boards -- boards
+          which aren't supported using the standard "dumb" serial driver.
+          This includes intelligent serial boards such as Cyclades,
+          Digiboards, etc. These are usually used for systems that need many
+          serial ports because they serve many terminals or dial-in
+          connections.
+
+          Note that the answer to this question won't directly affect the
+          kernel: saying N will just cause the configurator to skip all
+          the questions about non-standard serial boards.
+
+          Most people can say N here.

+          This driver supports the entire family of Intelliport II/Plus
+          controllers with the exception of the MicroChannel controllers and
+          products previous to the Intelliport II. These are multiport cards,
+          which give you many serial ports. You would need something like this
+          to connect more than two modems to your Linux box, for instance in

+          The Cyclades-Z family of multiport cards allows 2 (two) driver op
+          modes: polling and interrupt. In polling mode, the driver will check
+          the status of the Cyclades-Z ports every certain amount of time
+          (which is called polling cycle and is configurable). In interrupt
+          mode, it will use an interrupt line (IRQ) in order to check the
+          status of the Cyclades-Z ports. The default op mode is polling. If
+          unsure, say N.

+          The ACP modem (Mwave) for Linux is a WinModem. It is composed of a
+          kernel driver and a user level application. Together these components
+          support direct attachment to public switched telephone networks (PSTNs)
+          and support selected world wide countries.
+
+          This version of the ACP Modem driver supports the IBM Thinkpad 600E,
+          600, and 770 that include on board ACP modem hardware.
+
+          The modem also supports the standard communications port interface
+          (ttySx) and is compatible with the Hayes AT Command Set.
+
+          The user level application needed to use this driver can be found at
+          the IBM Linux Technology Center (LTC) web site:
+          <http://www.ibm.com/linux/ltc/>.
+
+          If you own one of the above IBM Thinkpads which has the Mwave chipset
+          in it, say Y.
+
+          To compile this driver as a module, choose M here: the
+          module will be called mwave.

+          Give userspace access to the GPIO pins on the National
+          Semiconductor SCx200 processors.
+
+          If compiled as a module, it will be called scx200_gpio.
+
+config RAW_DRIVER
+        tristate "RAW driver (/dev/raw/rawN) (OBSOLETE)"
+        help
+          The raw driver permits block devices to be bound to /dev/raw/rawN. 
+          Once bound, I/O against /dev/raw/rawN uses efficient zero-copy I/O. 
+          See the raw(8) manpage for more details.
+
+          The raw driver is deprecated and may be removed from 2.7
+          kernels.  Applications should simply open the device (eg /dev/hda1)
+          with the O_DIRECT flag.

+          If you say Y here, you will have a miscdevice named "/dev/hpet/".  Each

+          If you say Y here, you will disable RTC_IRQ in drivers/char/rtc.c. It
+          is assumed the platform called hpet_alloc with the RTC IRQ values for
+          the HPET timers.

+          the HPET registers.
+
+          In some hardware implementations, the page containing HPET
+          registers may also contain other things that shouldn't be
+          exposed to the user.  If this applies to your hardware,
+          say N here.
