Abstract:
1. A computer system comprising: a central processing unit; a computer core logic controller adapted to coordinate communications over a data communications bus; an integrated graphics subsystem adapted to generate display data in response to a set of rendering information; a graphics connector adapted to communicate with an auxiliary graphics subsystem; a data communications bus connected with the computer core logic controller and including a first bus connection adapted to communicate a set of rendering information from the computer core logic controller to the integrated graphics subsystem, a second bus connection adapted to communicate information between the integrated graphics subsystem and the graphics connector, and a third bus connection adapted to communicate information from the graphics connector to the computer core logic controller; wherein the integrated graphics subsystem includes a normal operation mode adapted to communicate information to the computer core logic via the second bus connection and the third bus connection, and also includes a data forwarding mode adapted to communicate a set of rendering information received via the first bus connection with an auxiliary graphics subsystem via the second bus connection.
