This is the same Zenith mobo as before. I uploaded a few more pictures in case they are any use to you.
I'm using a "modern" Dell PS/2 keyboard. Total Hardware helped me identify my Dell mobo, but nothing in there looks anything like the ZDS board I have. The SX2 is supposed to be a 50MHz chip, but it shows up as 66MHz and runs. Any idea what that's about? Do you think that the jumpers could already be correct?
As far as jumpers go, I'm in the dark. The board is heavily marked, but some labels are pretty cryptic.
Immediately around the CPU are the following jumpers and labels:
J34 - Jret
J36 - J(3.3V)
J37 - Jmul
J38 - Jklk
J39 - Front Panel
J40 - Jepk
J41 - Jfane
