Thank you for your responses to my question. All but one of the responses indicated that an XT harddisk controller could be made to work in an AT, and could be booted. It is apparently important, however, to configure the computer, via the SETUP program, as if it had no harddisk. The XT harddisk BIOS is then detected at C800 during boot. The harddisk will then be bootable, but it won't have the speed of an AT controller/drive. If the system also contains an AT controller, whether or not it has a drive hooked up, the situation is harder to resolve. The one negative response had been unable to get the XT harddisk to be bootable, but it was otherwise useable. Thanks again. Gary I. Kahn kahn@odu.edu
