Well that's only one side of the truth. AMD had in those K6 series an
very fast loop optimation. It was so fast, that Windows couldn't boot
correctly, because they did also counting down a counter. The result was
used as a dividend which caused and division by zero. AMD removed this
optimation later, since most people thought it was AMD fault and not
MS... It might be the same here.
