Re: Cyrix incompatible w/Pentium

I was expecting this. AMD licensed MMX directly from Intel [presumably INTC gets a license fee on each K-6 sold]. Cyrix did their own. The chances of at least a minor screw-up in taking this approach were substantial, and it looks like Cyrix did not disappoint. The interesting thing is that Soap will run with a non-MMX Pentium, but it is MMX enabled if MMX is detected [per their booth at Comdex last week]. Undoubtedly, the software detects MMX as present with the Cyrix chip, unless it is the older Cyrix chips that have the problem [which could be the case, Metatools didn't specify WHICH Cyrix chips were incompatible]. If that's so, the workaround might be to "force" a non-MMX mode even when MMX was detected. Too bad there's no clear way to do this. Doesn't matter, doesn't matter even if the problem gets fixed, this will do Cyrix substantial harm. A major compatability problem is the one thing that neither AMD nor Cyrix can afford, their worst nightmare.
