Hello all. I'm not familiar with the finer points of i386 hardware,
hopefully this problem isn't a big deal. But I'm looking for a new
motherboard just in case.

I have an older Abit BP6 running NetBSD 2.0.2 that I'm in the process
of upgrading so I can install either 3.0.1 or 3.1 on.

For a while I've known that I can't add any more PCI cards to it,
weird stuff happens. But last weekend all I did was replace one of the
hard drives for a bigger one and I got a weird problem.

I have a Promise ATA133 controller so I can use newer large disks. I
have 4 disks on it (max), but when I replaced a 300 gig drive with a
500 gig drive, for some reason my 10baseT ISA network card (3com
3C509B) stopped working. It has a link light, but if I ping it's
address, it doesn't work. If reboot and unplug the 500 gig drive, the
card works.

The kernel is almost generic, I only added MP and increased
nmbclusters I think. Maybe made a few changes to run Postgres.

Here's the dmesg (wd3 would be a 500 gig Maxtor disk):
