I have one of these cards also and after fiddling a bit with the source
found that the checksum in the probe fails. I commented it out and am
using the card successfully, NFS mounting to and from my Sun3s with no
problems.
in if_we.c, change it to something like...
--- cut ---
/*
* Here we check the card ROM, if the checksum passes, and the
* type code and ethernet address check out, then we know we have
* a wd8003 card.
*
* Autoconfiguration: No warning message is printed on error.
*/
for (sum = 0, i = 0; i < 8; ++i)
sum += inb(is->id_iobase + WD_ROM_OFFSET + i);
if (sum != WD_CHECKSUM)
{
printf("we: probe: checksum failed... installing anyway\n");
/* return (0); */
}
sc->we_type = inb(is->id_iobase + WD_ROM_OFFSET + 6);
--- cut ---
Since irq2 == irq9, I kept the INSTALL.NOTES defaults for the settings
and the only changes I made to the cards defaults was to set the irq
jumper to IRQ9 (2), and I think I took off the boot prom jumper although
there isn't a prom anyway.

I don't completely understand the PROM and memory addressing myself...
can someone explain this? Unless I'm missing something, I only see
how to set the prom address and not how to pick where the iomem goes.
