|
|
.Sh DESCRIPTION
|
|
The

|
driver provides support for the PCI bus present on Prometheus Zorro III to PCI
|
|
bridge card.

driver was written by

|
|
.Sh BUGS
|
|
The hardware does not support DMA to host memory.
|
|
.Pp
|
|
The Prometheus does not support repeating of PCI transactions, instead if the
|
|
PCI card demands a retry of transaction, it returns value 0xFFFFFFFF.
|
|
This is currently not handled by the
|
|
.Nm
|
|
driver and will confuse some PCI card drivers.
