CARDBUS(4)                OpenBSD Programmer's Manual               CARDBUS(4)

NAME
     cardbus, cbb - introduction to CardBus support

SYNOPSIS
     cbb*      at pci? dev? function ?
     cardslot* at cbb? flags 0x0000
     cardbus*  at cardslot?
     pcmcia*   at cardslot?

DESCRIPTION
     OpenBSD provides machine-independent bus support and drivers for CardBus
     devices.

     The flags are used with cardslot definition.  The lowest order (right-
     most) bit of defines the PC Card attach sequence at boot-time.  When the
     bit is set, a PC Card in the slot is probed and attached immediately.
     However, the PC Card is probed after kernel thread wakes up.  If a PC
     Card is used as a boot device (e.g., CF card or network card), you should
     set this bit to 1.

SUPPORTED DEVICES
     OpenBSD includes the following machine-independent CardBus drivers, sort-
     ed by function and driver name:

   Network interfaces
        dc(4)    Intel 21143 and Xircom X3201-based Ethernet interfaces.
        fxp(4)   Intel PRO/100 CardBus II Ethernet interfaces.
        xl(4)    3Com 3c575 and 3c656-based Ethernet interfaces.

HISTORY
     The cardbus driver first appeared in NetBSD 1.5.  OpenBSD support was
     added in OpenBSD 2.7.

OpenBSD 2.9                    November 14, 1999                             1
