About a year or so ago the de driver broke for my early version 21040
card. Ended up putting an NE2000 clone on ISA to get by. Later
installed an Adaptec 2742 or 2842 (I forget, the VL-bus one) and tried
to get it working. And haven't paid much attention to either until
recently.
The VL Adaptec appears to work but won't boot my 4G IBM DCAS HD. Wonder
if 4G was too much for it. Or "geometry" or something is wrong. Only
mention this because the Adaptec was on IRQ 15. Noticed de0 was also
getting IRQ 15. This is with 2.2.7-RELEASE. But couldn't ifconfig de0
because "interface does not exist". Yet it was listed in dmesg.
So I got the great idea to move the Adaptec IRQ to 10. This time dmesg
doesn't list the de0 at all.
Removed the Adaptec and now the de0 is detected but looks like this:

1996 AMI BIOS doesn't have provisions for assigning IRQ to the card the
way the Award BIOS does on this Asus P6NP5.
Other than The Real Solution: Go Buy New Intel Ethernet Card and Ditch
This Cheap Junk MB Too, is there something I could/should do? There
doesn't appear to be a way to assign an IRQ in the kernel config.
