Thanks CJT,

I can't determine which jumper should be set where. These are some upgrade
boards, apparently manufactured by Sun. I don't have any pertinent
information like part numbers or model numbers. They are not the same as
Sparc 20s or Ultra-2's, even though prtdiag claimed its's an Ultra-2. At
least the jumpers are named differently, located somewhere else, or buried
under something where I can't see it.

I did not even open the box when I attempted the update, just tried it. I
have opened the box now, but don't see any jumper. I have browsed the
motherboard docs at sun and don't see any that resemble this one.

I will try on Monday to see if anyone has any of the old purchase records
for these motherboards.

Thanks,
Tom
