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.

To Upgrade Boot Monitor V1.X to V2.x (2.9 is latest) requires changing EPROMs, moving J102, and changing/torturing a PAL chip. The exact details will be forthcomming in a week or so in the ZUpGrade Series. This should give me enough time to refind the info... Cheers, Gern -------
