A friend of mine has an old Mitsubishi 386.  Either because of a problem
or simply by being an older computer, it does not support a 3.5 drive.  He
thought this was a good opportunity to upgrade the hard disk controller
from a 3/1 to 1/1 interleave and get a card that will also support the
floppies (e.g. a DTC 7280).

The problem is that the floppy controller is on the mother board and the
DTC (and I assume other such cards) floppy part will not work while the
other is active.  Is there a way to disable the embedded floppy controller?
Jumper on the mother board?  A chip that can be removed?  Cut the whole thing
away?
 
  Thanks,
