I cannot determine the BIOS or chipset information from here at work, at
least from the Vectra's PDF manuals. I will try and look later when I get
home, along with trying that config option.
I will say that the docs say that the motherboard is APIC compatible. And
if you had really read my message, I said that the procs are not
identical. They are the same stepping, but different models. However, for
all intents and purposes, the BIOS correctly sees both procs, and I
thought Linux did also up until the point of the APIC problem.
If needed I will try and look for another identical processor to one of
them. But I need definite assurance that the fact that they're different
models *IS* the problem.
Like I said, I'll try that config switch when I get home. Thanks for any
more answers!
