For 10-bit wide cards, 0x300-0x3ff is used, and this is satisfactory. For 12-bit wide cards, however, it would nice to use 0x400-0xfff, however this causes some problems for some specific PCMCIA devices, as well as some specific laptops; consequently, 0x300-0x3ff is used.
p Unfortunately, the choice of 0x300-0x3ff causes problems as well. In particular, a number of video devices are mapped in that range, and may conflict. In the event that pcmcia devices are mapped in 0x300 and appear to be nonfunctional, remapping to 0x400-0xfff may be appropriate; consult .Cd options PCIC_ISA_ALLOC_IOBASE and .Cd options PCIC_ISA_ALLOC_IOSIZE in .Xr options 4 . Example: d -literal -offset indent # Avoid pcmcia bus space conflicts with the default io space # allocation on 12-bit wide busses (base 0x300 size 0xff). options PCIC_ISA_ALLOC_IOBASE=0x400 options PCIC_ISA_ALLOC_IOSIZE=0xbff .Ed
