I've orded a new board and processor and am just wonder if I'll need to reformat to install them. I know the system devices all have to be reinstalled but I have a somewhat vague memory of being able to merely delete the enum key in the registery and reboot, then windows would reinstall those devices. Although another fact that I do recall is that this specific key is Win95/98/ME only.. anyone know of a similar way of doing this in 2000?
