Abstract
An apparatus and a method for supporting coexistence of an external AGP graphics adapter with an embedded graphics adapter. The embedded graphics adapter may be regarded as a PCI device, and the graphics memory of embedded graphics adapter is integrated into DRAM of a computer system. The corelogic and software capable of graphics address remapping and directed accessing graphics memory of the embedded graphics adapter for supporting external AGP graphics adapter and embedded graphics adapter respectively. The embedded graphics adapter could be an AGP device while the external graphics adapter would be a PCI device, and vice versa.
