The system uses a 15-pin high-density D-subminiature connector on the back panel

for attaching a video graphics array (VGA)-compatible monitor to your system. The

video circuitry on the system board synchronizes the signals that drive the red, green,

and blue electron guns in the monitor.

NOTE: Installing a video card automatically disables the system's built-in video

subsystem.

If you reconfigure your hardware, you may need pin number and signal information for

the video connector. Figure B-6 illustrates the pin numbers for the video connector,

and Table B-5 lists and defines the pin assignments and interface signals for the video

connector.
