Could someone with an old machine please verify that this code returns ZERO if MMX is not present.

Sorry Mike, I don't have an old pc at hand here, but maybe this also helps:

I just picked an old machine from my scrap collection - equipped with a Pentium S 100MHz (the one in the ceramic case), and, luckily, also with Win95B.

This is the result of VerifyMMX:
