System Overview

2.3.9 Graphics Subsystem

These systems use the Q35 GMCH component, which includes an integrated graphics controller

that can drive an external VGA monitor. 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.

The IGC supports dual independent display for expanding the desktop viewing area across two

monitors. The USDT form factor includes a DVI-D interface for direct connection with a digital

video monitor. The graphics subsystem of the SFF and CMT systems can be upgraded by

installing an SDVO ADD2 card or PCIe x16 graphics card in the PCIe x16 graphics slot.

2.3.10 Audio Subsystem

These systems use the integrated High Definitions audio controller of the chipset and the ADI

AD1884 High Definition audio codec. HD audio provides improvements over AC’97 audio such

as higher sampling rates, refined signal interfaces, and audio processors with a higher

signal-to-noise ratio. The audio line input jack can be re-configured as a microphone input, and

multi-streaming is supported. These systems include a 1.5-watt output amplifier driving an

internal speaker.

All models include front panel-accessible stereo microphone in and headphone

out audio jacks.
