DESCRIPTION

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


SUPPORTED 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
                    modems.

   Network interfaces
           awi      BayStack 650 wireless 802.11FH controller.
           cnw      Netwave AirSurfer Wireless LAN interface.
           ep       3com 3c589 Etherlink-III Ethernet card.
           mbe      Ethernet card based on the Fujitsu MB86960A/MB86965A
                    chipset.
           mhzc     Megahertz Ethernet/Modem combo cards
           ne       NE2000 compatible cards.
           ray      Raytheon Raylink and WebGear Aviator2.4 802.11 controller.
           sm       Megahertz Ethernet card.
           wi       Lucent WaveLan/IEEE 802.11 controller.

   SCSI controllers
           aic      Adaptec APA-1460 SCSI controller card.
           esp      NCR 53C9x, Emulex ESP406, and Qlogic FAS408 SCSI con-
                    trollers.

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).
