I understand, but since there's no clear dividing line (quality motherboards
could be much older and work fine with dummy nops, cheap ones could be newer
and not work), I put that in as a guideline based on someone's comment of
'anything made in the last 5 years'. I think people working with very old
boards would expect to have to be away of incompatibilities like this
(and CYRIX_CACHE_REALLY_WORKS) for example.
