Underclock a Pentium/Overdrive/486

Hi Most current processors use PLLs to create the actual clock that runs the processor. While one can change things digitally with jumpers that change the dividers coming out of the PLLs there is not a lot that can be done with changing the reference clock. The PLLs will lock down to some lower frequencies but it may have a hard time keeping lock if one dropped it too low. I don't know what the pentiums use but the AMD parts use a 200MHz reference. With early K8 stuff, I ran these down to about a 80MHz clock someplace without things going bad. Below that, the oscillator wouldn't go any slower. I've no idea what todays chips would do.
