Ahh, from the EPIA HOWTO:
13.2. Is the C3 Pentium compatible?
Yes. But Samuel 2, Ezra, Ezra T C3 processors have a problem with
the cmpxchg8b (i.e. CMOV) opcode. Nehemiah and Antaur processors
are not affected.
However, that would imply that you don't have a VIA C3-2 (Nehamiah) at
all, but the older original CyrixIII/VIA C3.
Can you check? The Nehemian (C3-2) should be model 9 or greater.
So afaik, you should use MCYRIXIII, and make _that_ be the one that
disables the use of the cmpxchg8b instruction.
Can you please verify?
