I have an "old" motherboard with version 1.2 boot ROM, and would
like to upgrade to a newer boot ROM version.  What is the highest
boot ROM version (& part #?) that will work with the old motherboard,
and how should J101/J102 be set?

I bought a 2.x ROM from Heath over a year ago, but my system
would not boot with it (trying every combination of J101/J102), 
so I sent it back for a refund.  As I remember, the system would
beep once and that was it.  Since I had S101 set for auto boot,
I don't know if it would have gotten as far as the "hand prompt"
or not.

Thanks in advance for any information.
