Unscrew the two screws holding the circuit board to the bottom of the drive and carefully lift it up. Along one edge of the circuit board you will find a place where it would appear that a resistor should be -- this place is marked R7. Solder a jumper into that spot to make this drive into an RD53. Set the drive select jumper to DS2 and you should be in business.

On the swing-out logic board, there's an empty position labeled R7. Insert a jumper there (you'll need a soldering iron).
