System Overview

2.4.9 Graphics Subsystem

These systems use the 82915G or 82915GV GMCH component that integrates an Intel graphics
controller that can drive an external VGA monitor. The integrated graphics controller (IGC)
features a 333-MHz core processor and a 400-MHz RAMDAC. The controller implements
Dynamic Video Memory Technology (DVMT 3.0) for video memory. Table 2-5 lists the key
features of the integrated graphics subsystem.

through a PCI Express x16 graphics slot. The IGC of the 82915GV used in the USDT form
factor does not support a PCI Express x16 graphic slot and may only be upgraded through the
PCI 2.3 slot.

These systems use the integrated AC97 audio controller of the chipset and the ADI 1981B audio
codec. These systems include microphone and line inputs and headphone and line outputs and
include a 3-watt output amplifier driving an internal speaker. All models feature front
panel-accessible microphone in and headphone out audio jacks as standard.
