drive bay using the four screws (two on each side) that
came with the drive.

If you are installing an IDE hard disk drive, see page 45 for
instructions on connecting the ribbon cable to the main
system board (if necessary) and the drive.
If you are installing a diskette or tape drive, use the
appropriate connector on the diskette drive ribbon cable. If
your drive has a header connector, be sure to align pin 1 of
the drive connector with the side of the ribbon cable
containing the red wire. If your drive has a card-edge
connector, align the key-way in the ribbon cable connector
with the gap in the drive connector.
If you are installing another type of drive, see the
documentation that came with it for instructions on
connecting its drive ribbon cable.
