.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
driver controls the pccard subssytem.
|
||
|
|
The

.Pp
|
||
|
|
The following
|
||
|
|
.Tn ISA
|
||
|
|
devices, or true clones, are supported in the current code.

|
|
.It Intel i82365SL-DF
|

|
|
.Tn Intel's last version of this device.
|
||
|
|
3.3V support was added.
|
||
|
|
.It VLSI 82C146
|
||
|
|
An older VLSI part with some issues on some machines.

.It Cirrus Logic PD-6720
|
||
|
|
.It Cirrus Logic PD-6722
|
||
|
|
Cirrus Logic's pcic controller.
|
||
|
|
Compatible with the i82365sl STEP C with the addition of a different
|
||
|
|
3.3V control.
|
||
|
|
.It Ricoh RF5C296
|
||
|
|
.It Ricoh RF5C396
|
||
|
|
Ricoh's pccard bridge chips.
|
||
|
|
These are compatible with the i82365sl step C, but with yet another
|
||
|
|
different 3.3V control.
|
||
|
|
.It Vadem 365
|

|
||
|
|
.It Vadem 468
|
||
|
|
.It Vadem 469
|
||
|
|
Like the earlier Vadem models, but with Vadem's own, incompatible, 3.3V
|
||
|
|
control system.
|
||
|
|
.It IBM PCIC
|
||
|
|
.Tn IBM
|

|
|
clone of the original i82365sl part, with its own id register value.
|
||
|
|
Has no 3.3V ability.
|
||
|
|
.Tn IBM KING
|
||
|
|
.Tn IBM
|
||
|
|
A strange clone of i82365sl.
|
||
|
|
This part has many restrictions not found in the i82365sl, plus some
|
||
|
|
strange power control. It has not been tested in ages, but is
|
||
|
|
believed to work.
|
||
|
|
.El
|
||
|
|
.Pp
|
||
|
|
Many other vendors made parts in this arena, but most of them were
|
||
|
|
compatible with one of the above chipsets.
|
||
|
|
.Pp
|
||
|
|
The following PCI cardbus and pcmcia bridges are supported:

|
|
have good access to machines with one of these bridges in it.

|

Offerrides the IRQ to use for ISA interrupt routing.
|

|
|
.It hw.pcic.ignore_function_1
|
||
|
|
Needed for some, improperly manufacturered pci cards made by orinoco.
|
||
|
|
It disables function 1 completely.
|
||
|
|
Set to 0 to enable function 1.
|
||
|
|
Set to 1 to disable function 1.
|
||
|
|
.It hw.pcic.intr_path
|
||
|
|
Should pci pcic devices route interrupts via ISA or PCI.
|
||
|
|
A value of 1 means default via ISA.
|
||
|
|
A value of 2 means route via PCI.
|
||
|
|
.It hw.pcic.init_routing
|
||
|
|
Some machines can tolerate interrupt routing selection at the cardbus
|
||
|
|
bridge level.
|
||
|
|
Others fail when you mess with these registers.
|
||
|
|
Set to 1 to force the chipset to route via parallel pci interrupts (as
|
||
|
|
well as a few other little things).
|
||
|
|
Set to 0, the default, forces the code to leave these registers as the
|
||
|
|
code finds them.
