There does not seem to be any built-in support for 1.2MB drives on PS/2's, e.g., there is no way to tell a PS/2 that it has a 1.2MB/5.25" drive via the IBM supplied reference disk. I assume that the IBM 1.2MB drive kit includes a driver to supply the support, but I've never encountered one of these costly behemoths. >Meanwhile, our IBM 3090 repair person will try to order >the screwdriver needed to manipulate a TORX screw with a center post! I just use a small long-nosed pliers to snap the post off. However, there really is a tool available for the purpose. Jensen Tools and Specialized Products both have the requsite tools, which I believe are marketed by the Xcelite division of Cooper Tools. Send me mail if you can't locate their address; I'd list them now but I'm not at my office.
