> the "non-odd" CPUs (200,300,400) are supported, but the "odd" CPUs (anything > that isn't a Mhz based on 100Mhz) aren't. at least in the older machines. Except for the 167MHz CPUs, which do work in the U2. Actually, according to the FEHB, there should be a way to do 250's in the U2 as well, but none were ever supported. -Pete
