Follow these steps:
1. If you have not already done so, follow the instructions on
page 2-16 (“Installing an Option Card”) to install the
graphics adapter card in your computer.
2. Attach one end of the cable to the alternate VGA interface on
the main system board near the back panel, as shown
below. Align the cable so the red wire along one edge is
closest to pin 1 in the socket.
3. Connect the other end of the cable to the appropriate
interface on the adapter card. (Check your graphics card
manual for instructions.)
