DESCRIPTION
     NetBSD provides machine-independent bus support and drivers for PCMCIA
     (Personal Computer Memory Card International Association) a.k.a.  PC
     Card, CardBus devices.

HARDWARE
     NetBSD includes the following machine-independent PCMCIA drivers, sorted
     by function and driver name:

HISTORY
     The pcmcia driver appeared in NetBSD 1.3.

BUGS
   IO space conflicts
     NetBSD probes the PCMCIA IO bus width and uses that information to decide
     where to map PCMCIA IO space. For 10-bit wide cards, 0x300-0x3ff is used.
     For 12-bit wide cards, 0x400-0x4ff is used.

     Neither choice is perfect. In the 12-bit case, 0x400 appears to work on
     substantially more devices than 0x300. In the event that PCMCIA devices
     are mapped in 0x400-0xfff and appear to be nonfunctional, remapping to
     0x300-0x3ff may be appropriate; consult
     options PCIC_ISA_ALLOC_IOBASE and
     options PCIC_ISA_ALLOC_IOSIZE in options(4).  Example:

           # Avoid pcmcia bus space conflicts with the default io space
           # allocation on 12-bit wide busses (base 0x400 size 0xfff).
           options PCIC_ISA_ALLOC_IOBASE=0x300
           options PCIC_ISA_ALLOC_IOSIZE=0x0ff

   Interrupt conflicts
     NetBSD attempts to probe for available interrupts to assign to PCMCIA de-
     vices. In some cases, it is not possible to detect all interrupts in use;
     in such cases, use of
     options PCIC_ISA_INTR_ALLOC_MASK may be necessary. See options(4).

   Unconfigured devices
     During autoconfiguration, if a message is displayed saying that your card
     is "not configured" it indicates that there isn't support for your card
     compiled into the kernel.  To fix this problem, it may simply be a matter
     of adding the manufacturer and product IDs to the PCMCIA database or
     adding a front-end attachment to an existing driver.  In the latter case,
     it is normally always necessary to get a dump of the CIS table from the
     card.  You can do this by adding
     options PCMCIACISDEBUG and
     options PCMCIADEBUG into your kernel config file.  Additionally, you will
     have to patch the kernel to enable run-time debugging.  This can be done
     in the source by changing the variables pcmcia_debug and pcmciacis_debug
     to 0xff.  Alternatively, you can patch the same variables at run-time us-
     ing ddb(4).  For most drivers you should also consider enabling any driv-
     er-specific debugging options.
