Abstract:
An apparatus for supporting multiple graphics adapters in a computer system, comprising:an embedded graphics adapter having an AGP interface and a PCI interface; a corelogic having a memory controller signally-connected to a graphics memory of the embedded graphics adapter; an AGP bridge signally-connected with the AGP interface and the memory controller; and a PCI bridge signally-connected with the PCI interface and the memory controller, wherein when an external AGP graphics adapter exists in the computer system, the embedded graphics adapter transfers data to the memory controller via the PCI interface and the PCI bridge using PCI transactions, and wherein when an external PCI graphics adapter exists in the computer system, the embedded graphics adapter transfers data to the memory controller via the AGP interface and the AGP bridge using AGP transactions.
