6.3.2 NVIDIA GRAPHICS PROGRAMMING

The NVIDIA graphics controller is configured through PCI configuration registers and controlled
through memory-mapped registers by an appropriate software driver.

6.3.3 NVIDIA GRAPHICS UPGRADING

The method of upgrading the NVIDIA graphics controller is determined by the system type.
Compaq Deskpro EN Small Form Factor: No AGP slot is provided for upgrading the NVIDIA
graphics on Deskpro EN SFF models, which have the NVIDIA graphics controller embedded on
the system board. Since PCI graphics adapters are generally considered inferior to AGP types, a
true "upgrade" is not possible on these systems. However, dual-monitor support is possible by
adding a PCI-type graphics card.
Compaq Deskpro EN Slim Desktop/Configurable Minitower: Upgrading the AGP graphics is
facilitated by replacing the existing nVIDIA graphics card with another AGP graphics adapter
card. During POST, the BIOS will detect the presence of the AGP graphics adapter in the AGP
slot and inhibit the integrated controller of the 82815 GMCH. Dual monitor support is possible by
adding a PCI graphics card.
