CONFIG_PCMCIA
  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.linuxdoc.org/docs.html#howto>.

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

CONFIG_CARDBUS
  CardBus is a bus mastering architecture for PC-cards, which allows
  for 32 bit PC-cards (the original PCMCIA standard specifies only
  a 16 bit wide bus). Many newer PC-cards are actually CardBus cards.

  This option enables support for CardBus PC Cards, as well as support
  for CardBus host bridges.  Virtually all modern PCMCIA bridges are
  CardBus compatible.  A "bridge" is the hardware inside your computer
  that PCMCIA cards are plugged into.

  To use your PC-cards, you will need supporting software from David
  Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
  for location).

  If unsure, say Y.

CONFIG_I82092
  This provides support for the Intel I82092AA PCI-to-PCMCIA bridge device,
  found in some older laptops and more commonly in evaluation boards for the
  chip.

CONFIG_I82365
  Say Y here to include support for ISA-bus PCMCIA host bridges that
  are register compatible with the Intel i82365.  These are found on
  older laptops and ISA-bus card readers for desktop systems.  A
  "bridge" is the hardware inside your computer that PCMCIA cards are
  plugged into. If unsure, say N.

CONFIG_TCIC
  Say Y here to include support for the Databook TCIC family of PCMCIA
  host bridges. These are only found on a handful of old systems.
  "Bridge" is the name used for the hardware inside your computer that
  PCMCIA cards are plugged into. If unsure, say N.
