Installing a Floppy Drive
1. If you are replacing a drive and the new 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 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).

2 bracket rails (2)
3 screws (4)
