Is it possible to use a PCI card designed for Unix on Windows?

NTDEV
1

Hello All,

I have a PCI card which works on Unix (RISC - big
end).
When I try to use it on a PC, Win2k never comes up. I
haven’t seen where it’s hung, since I don’t have a
windbg setup ready.

Do you think, it might be a problem related to the
endianness of the system? Anybody aware of PCI cards
working across different endian systems?

Thanks,
Sajeev

Is the PCI device a bridge device?

Can it boot DOS? Do you have PnP OS selected in the BIOS? It should be off
(Non-PnP OS) for all NT derivatives.

PCI is a little-endian bus, and the host bridge is responsible for
translating any endian issues, so that’s not it.

Function 0 is Bridge and Function 1 is a Network

Your question made me to try with a card without
bridge. Win2k boots with it. Is there any caveat with
a bridge device on win2k?

Thanks a lot,
Sajeev

I ask, as Windows would not attempt to load a driver for this device unless
a.) it exposed a VID/DID that Windows recognized (had a driver registered
for), or b.) the device is a bridge device. Windows loads it’s own driver
for PCI bridge devices. If you didn’t have a bridge device, then that would
point fairly clearly to a hardware problem.

As function 0 is a bridge device, the problem is likely there.

At this point, I definitely think a kernel debugger is in order, that will
probably help you nail the source of the problem quickly.

Is your device multifunc compliant, as in does it have separate BARs and
such for the separate functions? If not, it’s very likely that is your
problem. If it does, there are some other issues this could be, some HAL
related. Hook up a debugger and feed us more info.
