is not a reasonable place to allocate 12-bit pcmcia iospace. It seems to cause conflicts on a large number of modern laptops, necesitating hand-patching of the kernel (mostly due to video devices in the upper range of that space). This will presumably cause problems on the NEC Versa 6030X, however that appears to be a vastly less common case than the laptops that are inconvenienced by the current state. 12-bit iospace now uses 0x400-0xfff.

.Sh HISTORY
|
|
The

|
driver appeared in
|
|
.Nx 1.3 .
|
|
.Sh BUGS
|
|
.Ss IO space conflicts
|
|
.Nx
|
|
probes the pcmcia IO bus width and uses that information to decide
|
|
where to map PCMCIA IO space. For 10-bit wide cards, 0x300-0x3ff is
|
|
used. For 12-bit wide cards, 0x400-0x4ff is used.
|
|
.Pp
|
|
Neither choice is perfect. In the 12-bit case, 0x400 appears to work
|
|
on substantially more devices than 0x300. In the event that pcmcia
|
|
devices are mapped in 0x400-0xfff and appear to be nonfunctional,
|
|
remapping to 0x300-0x3ff may be appropriate; consult
|
|
.Cd options PCIC_ISA_ALLOC_IOBASE
|
|
and
|
|
.Cd options PCIC_ISA_ALLOC_IOSIZE
|
|
in
|
|
.Xr options 4 .
|
|
Example:
|
|
.Bd -literal -offset indent
|
|
# Avoid pcmcia bus space conflicts with the default io space
|
|
# allocation on 12-bit wide busses (base 0x400 size 0xfff).
|
|
options PCIC_ISA_ALLOC_IOBASE=0x300
|
|
options PCIC_ISA_ALLOC_IOSIZE=0x0ff
