I agree with the other poster that VLB systems with more than 2 slots at
33MHz should be avoided. I would tend to blame your problems on the fact
that your VLB board is outside VLB 1.0 specs before condemning VLB as a whole.
I have one of the earliest VLB designs, a Micronics JX-30 (basically a
Gateway machine), with an ATI GUP VLB and a Buslogic BT445S, and only 2 VLB
slots; it has worked flawlessly in NetBSD, Linux, NT, Windows/DOS, and
OS/2 2.1.
