System Overview
2.3.9 Integrated Graphics Processor
These systems use the AMD RS780 component, which uses an ATI Radeon 3100 integrated
graphics processor featuring DirectX 10 technology that can drive an analog VGA monitor and a
DVI-D monitor. Table 2-4 lists the key features of the integrated graphics processor.
These systems also include a PCIe x16 graphics slot to ensure full graphics upgrade capabilities.
2.3.10 Audio Subsystem
These systems use the integrated High Definition audio controller of the chipset and the ADI
AD1884A High Definition audio codec. HD audio provides enhanced audio performance with
higher sampling rates, refined signal interfaces, and audio processors with increased
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, which can be muted with the F10 BIOS control. All models include front
panel-accessible stereo microphone input and headphone output audio jacks.
