6 Integrated Graphics Subsystem 6.1 Introduction This chapter describes graphics subsystem that is integrated into the 82915G/GV 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 Express x16 or the PCI 2.3 slot. The USDT form factor may be upgraded by installing 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 82915G GMCH will then be disabled (refer to section 6.5 for more information on upgrading the graphics subsystem).

Integrated Graphics Subsystem
6.1 Introduction
This chapter describes graphics subsystem that is integrated into the 82915G/GV 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 Express x16 or the PCI 2.3 slot. The USDT form factor may be upgraded by installing
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 82915G GMCH will then be disabled (refer to section 6.5 for more information on upgrading
the graphics subsystem).
