I'm trying to install an Adaptec AHA-1542CF in a 486 that's
already up an running NetBSD with an IDE hard drive.
I installed the card and get the following message at boot.
I've tried with two different SCSI drives and without any drive
and get the same messages.

I've check to make sure that I don't have any conflicts
on the IRQs between my com ports, NIC, and the SCSI card.

Do I have a dead 1542?
