subsystem provides machine-independent
bus support and drivers for PCMCIA (PC Card) devices.
provides support for the following devices. Note
that not all architectures support all devices.
- GemPlus GPR400 smartcard reader
- serial communications interface
- 3Com EtherLink III and Fast EtherLink III 10/100 Ethernet
- NE2000 and compatible 10/100 Ethernet device
- SMC91C9x and SMC91C1xx-based 10/100 Ethernet device
- Xircom-based 16-bit PCMCIA 10/100 Ethernet device
- Aironet Communications 4500/4800 IEEE 802.11FH/b wireless
- Xircom CreditCard Netwave wireless network device
- Marvell Libertas IEEE 802.11b/g wireless network
- WaveLAN/IEEE, PRISM 2-3, and Spectrum24 IEEE 802.11b
wireless network device
- Adaptec AIC-6260 and AIC-6360 SCSI interface
- WD100x compatible hard disk controller driver
The supported PCMCIA controllers are those that are i82365 compatible.
On some pcmcia
adapters, for instance the
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,
is the only driver
to require these modifications.
If the pcmcia
adapter is not detected, or if
events (such as card insertion) do not
occur, there may be a PCI card BIOS mapped in the same memory space the
driver is configured to use (this is often
the case with Ethernet card boot ROMs). The output from
contain a line beginning with “bios0” that lists the memory
address and size of mapped regions. If there is a conflict, you can use
to change the iomem parameter of the pcic
to a non-overlapping address, such as 0xd8000 for
. Some experimentation may be required to
find a working value; in some cases the size parameter of the
device may need to be decreased to avoid a
driver appeared in
