Along the way i've noticed that one of my memory
cards seems to be faulty,
it currently has 7mb of ram (4mb + 1mb + 1mb +1mb), after numerous
"Protection Bus Faults" I removed all but the 4mb card, and all is fine, i
was able to up it to 6 and isolate the faulty card. I'll probably end up
replacing most of the 4164 chips on that board, i think I have a box full
of them somewhere :)
You actually may not have any bad boards. If you look over the older archives
of the Suns-At-Home mailing list (
www.net-kitchen.com/~sah), you see this
problem referred to quite a bit. IIRC, you may just have to live with the
current situation or try to find a different board to replace the "bad"
one. Either way, 7mb is the max because of the video architecture.
