NetBSD provides machine-independent bus support and drivers for PCMCIA
(Personal Computer Memory Card International Association) a.k.a. PC
Card, CardBus devices.
NetBSD includes the following machine-independent PCMCIA drivers, sorted
by function and driver name:
Serial interfaces and modems
com 8250/16450/16550-compatible PCMCIA serial cards and
an Aironet 4500/4800 and Cisco 340 series 802.11 controller.
awi 802.11 controller based on the AMD PCnetMobile chipset.
cnw Netwave AirSurfer Wireless LAN interface.
ep 3Com 3c589 EtherLink III Ethernet card.
mbe Ethernet card based on the Fujitsu MB86960A/MB86965A
mhzc Megahertz Ethernet/Modem combo cards
ne NE2000 compatible cards.

The pcmcia driver appeared in NetBSD 1.3.
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).
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).
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.
