I thought you couldn't over clock a true AT? its my understanding that the original AT bios dated ~1984 would work ok if the machine was overclocked. later versions of the AT bios were fixed so overclocking will give you a post failure for your efforts. of course, my type 1 AT had an aftermarket bios so i didnt have that problem, and i could also specify custom drive types. david
