INTRODUCTION

This chapter describes graphics subsystems that are embedded on the system board. Two standard
graphics controller configurations are available:
♦ 815E-based graphics controller implementation - The graphics controller integrated into the
82815 GMCH is implemented and used to drive a video monitor.
♦ NVIDIA graphics controller implementation (Small Form Factor only) - The graphics
controller integrated into the 82815 GMCH is inhibited and an NVIDIA graphics controller
on the system board is used to drive a video monitor.
Both graphics subsystems employ the AGP interface allowing the use of system memory as well
as local RAM to provide efficient, economical 2D and 3D performance.
In Small Form Factor systems, the graphics controller of either implementation is resident
(embedded) on the system board and no AGP slot is available. Upgrading or modifying the
graphics controller on these systems is accomplished by adding a PCI graphics card.
In Slim Desktop and Configurable Minitower systems an AGP slot is provided. Upgrading these
systems is accomplished by simply replacing the GPA/AIMM or AGP graphics controller card in
the AGP slot. Separate AGP graphics cards are described in the Appendices of this guide.
This chapter covers the following subjects:
♦ Intel 815E-based graphics subsystem (6.2)
♦ NVIDIA-based graphics subsystem (6.3)
♦ Monitor power management (6.4)
♦ Monitor connector (6.5)
