Installing a Floppy Drive
1. If the replacement drive does not have the bracket rails attached, remove the rails from the old drive by removing the
two screws that secure each rail to the drive. Attach the bracket rails to the new drive by aligning the screw holes on
the drive with the screw holes on the bracket rails and then inserting and tightening all four screws (two screws on
each rail).
