I have an ASUS P2B-D motherboard with a single PII/450. I'd like to upgrade to two CPUs.
Intel has very cleverly discontinued the PII/450, leaving me with the following options:
1) installing a PII/400. I assume that the 4x frequency multiple is hard-coded onto the processor cartridge somehow. Has anyone tried running two CPUs at two different speeds in the same box simultaneously?
2) installing a PIII/450. I doubt there is any electrical compatibility problem, but I wonder if there is some trick to getting Linux to treat the PIII as a PII (i.e. it would be really bad if the kernel tried to enable MMX on both CPUs). Has anyone tried running two different model CPUs in the same box simultaneously?
3) Throw out/sell the PII and install two PIIIs. This option seems somewhat unappetizing.
I know there used to be problems running different revisions of the Pentium Pro together. Does anyone know what these problems were, and whether I would experience similar or worse difficulties with a PII/PIII mix?
