I had checked the archives before posting this and discovered that the
success of the search function is highly dependent on the values you
give it. I had made my search too restrictive and didn't find
anything of value.

I was told the problem was either the CPU board (which it wasn't) or a
bad SIMM (which it was). We've replaced the memory module in the
system and it is up and running again.

Thanks to everyone who replied.
