Integrated Graphics Subsystem

6.1 Introduction

This chapter describes graphics subsystem that is integrated into the 82945G GMCH component.

This graphics subsystem employs the use of system memory to provide efficient, economical 2D

and 3D performance.

The SFF, ST, MT, and CMT form factors may be upgraded by installing a graphics card into the

PCI-E or the PCI 2.3 slot. The USDT form factor may be upgraded by installing an ADD2

(reverse layout) card in the PCI-E slot or a graphics card into the PCI 2.3 slot. An installed PCI

Express or PCI 2.3 graphics controller card will be detected by the BIOS during the boot

sequence and the integrated graphics controller of the 82945G GMCH will then be disabled

(refer to section 6.4 for more information on upgrading the graphics subsystem).
