I have one but I am not the >overclocking cpu type. :) I prefer to stick with 37.5MHz PCI bus (75MHz mem. bus) since all my PCI cards are comfortable with it. :-) Of course, yes, you need to be in the experimenting mind-set before setting out on such a task... FWIW, this is with a FIC PA-2007 (VIA VP2 chipset), which works quite excellently with NetBSD. ----------------------------------------------------------------------------- Michael L.
