+	tristate "PCCard (PCMCIA/CardBus) support"
+	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: 16 bit PCMCIA and 32 bit
+	  CardBus cards.
+
+	  To compile this driver as modules, choose M here: the
+	  module will be called pcmcia_core.

+config PCMCIA
+	tristate "16-bit PCMCIA support"
+	depends on HAS_IOMEM
+	select CRC32
+	default y
+	help
+	   This option enables support for 16-bit PCMCIA cards. Most older
+	   PC-cards are such 16-bit PCMCIA cards, so unless you know you're
+	   only using 32-bit CardBus cards, say Y or M here.
+
+	   To use 16-bit PCMCIA cards, you will need supporting software in
+	   most cases. (see the file <file:Documentation/Changes> for
+	   location and details).
+
+	   To compile this driver as modules, choose M here: the
+	   module will be called pcmcia.
+
+	   If unsure, say Y.
+
+config PCMCIA_LOAD_CIS
+	bool "Load CIS updates from userspace"
+	depends on PCMCIA
+	select FW_LOADER
+	default y
+	help
+	  Some PCMCIA cards require an updated Card Information Structure (CIS)
+	  to be loaded from userspace to work correctly. If you say Y here,
+	  and your userspace is arranged correctly, this will be loaded
+	  automatically using the in-kernel firmware loader and the hotplug
+	  subsystem, instead of relying on cardmgr from pcmcia-cs to do so.
+
+	  If unsure, say Y.
+
+config CARDBUS
+	bool "32-bit CardBus support"
+	depends on PCI
+	default y
+	help
+	  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.
+
+	  To use 32 bit PC-cards, you also need a CardBus compatible host
+	  bridge. Virtually all modern PCMCIA bridges do this, and most of
+	  them are "yenta-compatible", so say Y or M there, too.
+
+	  If unsure, say Y.
