If you are installing your computer’s first hard disk drive,
you need to connect the hard disk drive ribbon cable to the
system board now. Follow the instructions on page 5-31
and then use the middle cable connector to connect the
hard disk drive as described below.
Notice the small tab in the middle of the cable connector;
align this tab with the notch in the hard disk drive
connector, as shown below.

When the hard disk drive ribbon cable is positioned correctly,
the red wire on the cable is aligned with pin 1 on the drive
connector. To identify pin 1, look for a 1 or 2 near the
connector on the drive’s circuit board.
Make sure the holes in the cable connector fit over all the
pins in the hard disk drive connector; then push in the
cable connector.
