Graphics Subsystem - Compaq Evo D500 Technical Reference Manual

Chapter 2 System Overview

2.4.9 GRAPHICS SUBSYSTEM

Two types of graphics subsystems are offered as standard in these systems; integrated and
external. The 82815 GMCH component includes an AGP 4X interface and a Direct AGP graphics
controller. The "integrated" configuration uses the graphics controller within the 82815 GMCH to
drive an RGB monitor. The "external" configuration features an AGP graphics controller that, due
to its presence on the AGP bus, disables the GMCH's integrated controller.
NOTE: Small Form Factor units do not have an AGP slot and are shipped as using the
integrated Direct AGP graphics solution or with an embedded NVIDIA TNT2 Pro
graphics controller. The customer must choose which graphics solution at the time of
purchase.
The Slim Desktop and Configurable Minitower units feature an AGP slot that is used for either
mounting a AGP graphics card or for mounting a GPA/AIMM card that supports the integrated
i740 controller. The AGP slot includes both Type 1 and Type 2 retention mechanisms. Dual-
monitor support is possible by adding a PCI graphics card to either configuration. Table 2-4 lists
the key features of the standard graphics subsystems employed in these systems:
