We have a 266MHz PII running with the latest red hat release (4.2).
Linux gives it 265 BogoMIPS and I've benchmarked it with our code (integer
CPU intensive) at being about 35% faster than a PP200 256k.

I don't think any current chip sets allow more than two PII chips yet in
addition to the problems already mentioned bellow.

| than 1GB according to a recent thread here. See

| the 2nd level cache it works, but is dog slow. Just switching
| off the 2nd level cache above 512MB doesn't work, as it then
| switches off the 1st level cache, too, for that area.
| It's pretty much impossible to find a 586 chipset that can
| cache more than 512MB (see another article in the paper
| version of the same magazine, c't 8/97), so if you need more
| you need either a PPro or a RISC processor.
