I'm posting this in hopes that someone might see a simple answer to this
before a long drawn out process ensues. Here's the problem: A friend of
mine has an older A2000 (one of the early revisions), and recently acquired a
Supra 8-meg memory board populated with 4 megs. The system also has a
BridgeBoard installed. When the system is cold started (dead start power-up)
it starts into the startup-sequence, then more often than not when it reaches
a certain point of using a given quantity of that memory it crashes with an
Illegal address or Illegal instruction guru. It is confirmed that it's not
the programs being executed from the startup-sequence, as changing them makes
no difference. So..a bad chip was suspected...logical, but no test so far has
found a single one. Supra seems to think there is nothing wrong with the
board...but here's another goodie: Running BindDrivers at ANY time
immediately locks the system. Needless to say, this makes the Bridgeboard
quite useless. The system works fine with some older Micron boards we've
tried it on...swapping chips does nothing, and we couldn't find a problme with
the originals anyway. Any ideas?

A scientist is one who finds interest in the kinetic energy of Jell-O
moving at ridiculous velocities...an engineer is one who can find a
real-life application for such silliness.
