I am attempting to get a BayStack AWI card to work in an ISA->PCMCIA
adapter that I got. It is a device that plugs into an ISA slot and cables
to a 3.5" adapter that has a VIA chip on it and two PCMCIA slots on it.
It will be my "cabled" side for a wireless lan around my house.
Here are the boot messages:
ncr0 at pci0 dev 11 function 0: ncr 53c875 fast20 wide scsi

awi0: could not run DAD, driver problem?
Since the adapter is on an ISA bus, I would expect it to use edge triggered
interrupts rather than level triggered ones, so I would expect an attempt to
share irq 5 should fail... I expect that it doesn't because most PCMCIA
adapters are not on ISA buses.
I expect I need to use something like:
to keep it away from the irq's that have been allocated to PCI devices...
Does this sound like the right diagnostic, or have I misread the problem?
