So, here's a look at the PB 486 board I have been working on. Posting mainly because a) to help others just as frustrated with their projects as I am and b) in case someone sees something I missed. I'll keep at it! Link in reply.

Well, powers on, but doesn't get past Phoenix BIOS error code 66 (heh). 1-1-4-1 (beep, beep, 4 quick beeps, 1 continuous beep). Apparently something about configuring advanced cache registers. I do not have any external cache. Gotta look that one up later. Could be jumpers.
