When a graphics card is installed in one of the system board slots, the video connectors on the graphics card and
the integrated graphics on the system board may be used at the same time. However, for such a configuration, only
the display connected to the discrete graphics card will display POST messages.
The system board graphics can be disabled by changing settings in Computer Setup.
