6.5 UPGRADING THE GRAPHICS SUBSYTEM
All models except those that use the USDT form factor are upgradeable by installing an AGP
graphics card into the AGP slot. The upgrade procedure is as follows:
1. Shut down the system through the operating system.
2. Unplug the power cord from the rear of the system unit.
3. Remove the chassis cover.
4. Install the AGP card into the AGP slot.
5. Replace the chassis cover.
6. Reconnect the power cord to the system unit.
7. Power up the system unit.
The BIOS will detect the presence of the AGP card and disable the IGC of the 82865G GMCH.
The IGC cannot operation concurrently with a separate AGP controller card installed but can
operate concurrently with a PCI graphics card. All models provide at least one PCI slot.
