6.6 UPGRADING 815-BASED GRAPHICS

Upgrading the 815-based graphics is facilitated with either the addition of the GPA card (to

improve the performance of the 82815 GMCH graphics controller) or with the installation of an

AGP graphics adapter card. During POST, the BIOS will detect the presence of the AGP graphics

adapter on the AGP bus and disable the 815-based graphics controller. Dual monitor support is

possible by supplementing the 815-based graphics controller with a PCI graphics card.
