CONFIG_SERIO
  Say Yes here if you have any input device that uses serial I/O to
  communicate with the system. This includes the 
		* standard AT keyboard and PS/2 mouse *
  as well as serial mice, Sun keyboards, some joysticks and 6dof
  devices and more.

  If unsure, say Y.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called serio.o. If you want to compile it
  as a module, say M here and read <file:Documentation/modules.txt>.

CONFIG_SERIO_I8042
  i8042 is the chip over which the standard AT keyboard and PS/2
  mouse are connected to the computer. If you use these devices,
  you'll need to say Y here.

  If unsure, say Y.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called i8042.o. If you want to compile it
  as a module, say M here and read <file:Documentation/modules.txt>.

CONFIG_SERIO_SERPORT
  Say Y here if you plan to use an input device (mouse, joystick,
  tablet, 6dof) that communicates over the RS232 serial (COM) port.
 
  More information is available: <file:Documentation/input/input.txt>

  If unsure, say Y.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called serport.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_SERIO_CT82C710
  Say Y here if you have a Texas Instruments TravelMate notebook
  equipped with the ct82c710 chip and want to use a mouse connected
  to the "QuickPort".

  If unsure, say N.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called ct82c710.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_SERIO_PARKBD
  Say Y here if you built a simple parallel port adapter to attach
  an additional AT keyboard, XT keyboard or PS/2 mouse.

  More information is available: <file:Documentation/input/input.txt>

  If unsure, say N.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called parkbd.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.

CONFIG_SERIO_ACORN
  Say Y here if you have the Acorn RiscPC and want to use an AT
  keyboard connected to its keyboard controller.

  This driver is also available as a module ( = code which can be
  inserted in and removed from the running kernel whenever you want).
  The module will be called rpckbd.o. If you want to compile it as a
  module, say M here and read <file:Documentation/modules.txt>.
