Hi all,

General question. Can the VRM slot on a socket 5 motherboard be used to get the voltages right for an MMX CPU?

I have found some references to the Semtech MP55 VRM for MMX CPUs.

My AST has an Intel Monaco board with the VRM socket present. I have a Pentium 200 in there now, and even have a Pentium Overdrive, but if I can plug in a VRM and get real support for split rail for MMX i'd love to do that instead.
