p 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, 16 bit drivers will need modification to handle this. So far, .Xr wi 4 is the only driver to require these modifications.
p If the .Nm adapter is not detected, or if .Nm events (such as card insertion) do not occur, there may be a .Tn PCI card BIOS mapped in the same memory space the .Nm driver is configured to use (this is often the case with Ethernet card boot ROMs). The output from .Xr dmesg 8 should contain a line beginning with .Dq bios0 that lists the memory address and size of mapped regions. If there is a conflict, you can use .Xr boot_config 8 to change the iomem parameter of the .Em pcic device to a non-overlapping address, such as 0xd8000 for .Em pcic0 . Some experimentation may be required to find a working value; in some cases the size parameter of the .Em pcic device may need to be decreased to avoid a conflict. .Sh SEE ALSO .Xr aic 4 , .Xr an 4 , .Xr awi 4 , .Xr cardbus 4 , .Xr cbb 4 , .Xr cnw 4 , .Xr com 4 , .Xr eisa 4 , .Xr ep 4 , .Xr gpr 4 , .Xr intro 4 , .Xr isa 4 , .Xr isapnp 4 , .Xr ne 4 , .Xr pci 4 , .Xr pcic 4 , .Xr ray 4 , .Xr rln 4 , .Xr sbus 4 , .Xr sm 4 , .Xr stp 4 , .Xr tcic 4 , .Xr tslot 4 , .Xr usb 4 , .Xr wdc 4 , .Xr wi 4 , .Xr xe 4 .Sh HISTORY The .Nm driver appeared in .Ox 2.3 .
