I'm running a FreeBSD box on a Cyrix P150+ without problem. Two items to
note:
* The Cyrix will report as a 486, so you will not get any of the 586
kernel optimizations (Somebody mentioned that the Cyrix chip did not
implement a full 586 instruction set, but I was under the
impression the Cyrix P150+ chips implemented the full 686 instruction
set *shrug*).
* They compare it to a P150/P166 etc, yet its floating point is NOT
comparable. However, its fixed precision mathematics are faster,
which is what I assume they are using to average the comparison. If
you are going to have a server with a lot of floating math an
intel chip would be a better choice, if you are simply going to
have a general server then the Cyrix chip would be a better chip (IMHO)
