S4??? motherboards and two AMD 200 series cpu's

Can anyone confirm that if you only use two cpu's in a Tyan quad opteron
motherboard everything will work fine? We just want to test some things
out first before we buy the full boat of CPU's and memory.

Thanks,

Steve

Yes, it will work fine with any number of CPUs

No, I haven't tested this myself on a quad opteron board, but all the SMP
boards I've used all work fine with just 1 CPU.

When you install Windows make sure you install the ACPI MPS HAL, because you
can't upgrade it afterwards. The easiest way to do this is to install with
more than 1 CPU present. But if you only have 1 CPU, when it says "Press
F6 to load mass storage drivers ..." press F5 (yes, F5, not F6) and it will
sooon present you with a choice of HALs. Choose ACPI MPS.

If your installing some other OS, check that such a problem won't also
affect you. I don't know other OS's well enough to say either way, though
I'd be surprised if Linux would give that problem. You probably know full
well that 'test' systems often end up as full production systems, so ensure
you build it like it's a production system.
