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 0x400-0x4ff 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 0x300 size 0xff).
           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
     devices. 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 neces-
     sary. 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 using
     ddb(4).  For most drivers you should also consider enabling any driver-
     specific debugging options.
