Abstract
A process includes, responsive to a computer platform being in a pre-operating system mode of operation, a first controller receiving serial data from a first external communication connector of the computer platform and the first controller providing a video output based on the serial data; and routing the video output of the first controller to a display device connector. The process includes, determining whether a video driver of the computer platform is communicating with a second controller via a second external communication connector of the computer platform. The video driver is associated with an operating system mode of operation of the computer platform. The process includes, in response to determining that the video driver is communicating with the second controller, routing a video output of the second controller to the display device connector in place of the video output of the first controller.
