I checked my July, 1988 first edition PC DOS 4.0 manual and it doesn't mention ED floppies at all. So ED must have come in during one of the (several) corrective service updates. I haven't booted up 4.0 to see if DRIVPARM or DRIVER understands the reference to ED, however. Printed manuals longa, Software brevis. --Chuck
