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.
