DESCRIPTION

     The pcmcia subsystem provides machine-independent bus support and drivers
     for PCMCIA (PC Card) devices.

SUPPORTED DEVICES

     The following devices are supported, sorted by function and driver name:

Miscellaneous

        gpr(4)
             GemPlus GPR400 smartcard reader.

Serial interfaces and modems

        com(4), pccom(4)
             8250/16450/16550-compatible PCMCIA serial cards and modems.

Network interfaces

        an(4)
             Aironet Communications 4500/4800 IEEE 802.11DS wireless controll-
             er.
        awi(4)
             BayStack 650 wireless 802.11FH wireless controller.
        cnw(4)
             Xircom Creditcard Netwave cards.
        ep(4)
             3Com 3c556, 3c562, 3c574, and 3c589 EtherLink III Ethernet cards.
        ne(4)
             NE2000 compatible cards.
        ray(4)
             Raytheon Raylink / WebGear Aviator IEEE 802.11FH 2Mbps wireless
             controller.
        rln(4)
             Proxim RangeLAN2 PC-Card.
        sm(4)
             Megahertz Ethernet cards.
        wi(4)
             WaveLAN/IEEE, PRISM-II and Spectrum24 IEEE 802.11DS cards.
        xe(4)
             Xircom 16bit Ethernet cards.

SCSI controllers

        aic(4)
             Adaptec APA-14[56]0 and NewMedia BusToaster SCSI controller
             cards.

IDE controllers

        wdc(4)
             Devices which implement an ATA/IDE interface, such as mini disk
             drives, CDROMs. This includes Compact Flash cards which emulate a
             disk drive.

     The supported PCMCIA controllers are those that are i82365 compatible.

NOTES

     On some pcmcia adapters, for instance the sbus(4)-based stp(4), the
     pcmcia bus will be mapped in big-endian format instead of the natural
     (and preferred) little endian format. Unfortunately such controllers lack
     the hardware facility to swap bytes, and it is not efficient to convert
     all drivers to always know about this. While 8 bit drivers can invisibly
     work on such a bus, 16 bit drivers will need modification to handle this.
     So far, wi(4) is the only driver to require these modifications.

     If the pcmcia adapter is not detected, or if pcmcia events (such as card
     insertion) do not occur, there may be a PCI card BIOS mapped in the same
     memory space the pcmcia driver is configured to use (this is often the
     case with ethernet card boot ROMs). The output from dmesg(8) should con-
     tain a line beginning with "bios0" that lists the memory address and size
     of mapped regions. If there is a conflict, you can use boot_config(8) to
     change the iomem parameter of the pcic device to a non-overlapping ad-
     dress, such as 0xd8000 for pcic0. Some experimentation may be required to
     find a working value; in some cases the size parameter of the pcic device
     may need to be decreased to avoid a conflict.
