If anyone knows details I would be very interested in: 1) How to do the int 25/26 2) What the FAT looks like 3) What directory entries look like 4) How to get this information (I tried but have been unsuccessful in ordering the tech ref for Compaq DOS 3.31). Thanks for any help. John Lefor 716-275-8265 716-248-9420 rochester!ur-valhalla!jal%galaxy University of Rochester Computer Studies Building Rochester, NY 14627
