In a specific embodiment, a system for providing video is disclosed, the system having a system bus, which in one embodiment is an Advanced Graphics Port (AGP) bus. The system bus is connected to a data bridge, which is connected to a second and third AGP bus. Each of the AGP busses are connected to graphics processors. The bridge routes data requests from one graphics processor to the second graphics processor without accessing the system AGP bus based upon a memory mapping information stored in a routing table or a register set. In another aspect of the present invention, the bridge responds to initialization requests using attributes that may vary depending on the specific mode of operation. Another aspect of the present invention allows for conversion between various AGP protocol portions.
