Hi.

A friend bought a 486-33 PC and in the middle of messing around
with it, he set the wait state value in CMOS to 2 (AMI BIOS).
Then the diagnostics programs reported that the CPU was running
like a 12-MHz 286!

Does anyone know why there can be such a big difference in CPU
speed when wait state is introduced?  Can someone explain?

Cheers,

Bugs
