John-
Notice that your Cyrix chip is a 6x86MX. This is a much newer chip than the
PR166 in question. The original was designed to replace a Pentium, but was
really a souped-up 486. The MX-series contained instructions similar to
MMX, and some of the Pentium-Pro capabilities. It was the equivilent of a
Pentium-II in some ways.

cyrix makes just fine. I thought I would put in my benchmarks here also.
This shows amd k6-III is 586 and much older cyrix is 686, go figure..

1:32 much quicker, just faster than PII 500 and 550
My intent was to run either with basically the same kernel config.
