I'm probably SOL here, but i thought i'd better ask in case anyone has
anything to say:

I've got a PCI <-> cardbus PCI card for use with a wavelan card that i want
to use in an old 486 machine (PhoenixBios v 4.04, "UMC 8880 PCI/ISA Ver 2.1
Dec 8, 94"), and it seesm that that bios isn't assigining the card an
interrupt:

cbb0 at pci0 dev 23 function 0: Ricoh 5C475 PCI-CardBus bridge (rev. 0x80)
cbb0: NOT USED because of unconfigured interrupt

The bios has an option (under "Advanced system setup" ->
"Pci devices") to change vairous things:

Enable Device {Enabled,Disabled}
Enable Master {Enabled,Disabled}
PCI INTA#       {most irq's}
Use Default LAtency Timer Value {Yes, No}
Latency Timer Value:    {0040}

I've tried most combinations and it dosn't make any difference. The PCIBIOS
stuff in the kernel does seem to help a little, but can't find the PCI IRQ
Routing info:

BIOS32 rev. 0 found at 0xfdb22
PCI BIOS rev. 2.0 found at 0xfdb83
pcibios: config mechanism [1][x], special cycles [x][x], last bus 0
pcibios_get_intr_routing: function not supported
No PCI IRQ Routing information available.

Are the differences between the PCI BIOS spec's v 2.0 and 2.1 such that the
irq info is laid out in a different way in 2.0, and NetBSD dosn't know how
to find it?

On another note, if i enable "options        PCIBIOS_BUS_FIXUP" the machine
resets just after the irq messages above.

I plan to dig around a bit more tonight, and see if ditching the sound card
helps.
