Abstract
An apparatus supports both (1) a cost-effective graphics device (such as an AGP device) integrated onto the motherboard, and (2) an upgradable computer system with an add-in card slot for receiving a second graphics device (such as a second AGP device) on a card. The apparatus is connected to a bus that has a first set of signals which is sensitive to noise. The apparatus also has a first switch connected to a first device, the first switch being connected to the first set of signals on the bus. The apparatus has a second switch which is adapted to be connected to a second device. The second switch is also connected to the first set of signals on the bus. The apparatus also has a detector connected to the first and second switches to enable the first switch if the first device is selected and otherwise enable the second switch.
