# 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 in 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 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 using ddb(4). For most drivers you should also consider enabling any driver-specific debugging options.
