The model number of the "old" drive is
FD55F-03-U and the model number of
the "new" drive is FD55BV-36-U. There are differences in the jumper
designations between the models so I can't readily map the settings.
First problem. The 'F' suffix means an 80 cylinder 2 head drive ('720K'
to the PC crowd), the 'B' suffix means a 40 cylinder 2 head one
('360K'). I doubt you'll boot an 80 cylinder disk using a 40 cylinder drive!
