J28, referring to the 'aux' plug in? From what I understand it's not
necessary.
When I set up mine, I went through hell trying to find a PSU that would work
that had an 'aux' connector... later to find out it wasn't needed. You just
need a 4pin molex connector and a 20pin motherboard connector, that should
do
the trick.

Another thing, did you bother to check if the issue might be with the Slot B
cartridges? Mine had some issue similar to yours. Have you tried removing 1
and then simply running on that one and see what happens? And then swapping
it with the second one and see if it worked as well?

The problem that I had was, whenever I run 'make -j2' it would crash after
a few secs/mins... lock tight as a drum. At first I thought it was a memory
error because 'top' would show 2gb of ram in full use then would use up all
1gb of swap file. When I swapped out the cpu cartridges, it pointed me in
the
right direction. Will L G
