.Sh INTRODUCTION
The
.Nm
subsystem provides machine-independent bus support and
drivers for PCMCIA (PC Card)
devices.
.Sh SUPPORTED DEVICES
The following devices are supported, sorted by function
and driver name:

.El
.Ss IDE controllers
.Bl -tag -width speaker -offset ind -compact
.It Xr 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.
.El
.Pp
The supported PCMCIA controllers are those that are i82365 compatible.
.Sh NOTES
On some
.Nm
adapters, for instance the
.Xr sbus 4 Ns -based
.Xr stp 4 ,
the
.Nm
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, but 16 bit
drivers will need modification to handle this.
.Xr wi 4
is the first driver to have these modifications.
