Introduction
1.3.7
Parallel ATA (PATA)
The PATA Host Controller supports three types of data transfers:
• Programmed I/O (PIO): Processor is in control of the data transfer.
• Multi-word DMA (ATA-5): DMA protocol that resembles the DMA on the ISA bus.
Allows transfer rates of up to 66 MB/s.
• Ultra DMA: Synchronous DMA protocol that redefines signals on the PATA cable to
allow both host and target throttling of data and transfer rates up to 100 MB/s.
Ultra DMA 100/66/33 are supported.
1.3.8
Intel® Graphics Media Accelerator 500 (Intel® GMA 500)
The Intel® SCH provides integrated graphics (2D and 3D) and high-definition video
decode capabilities with minimal power consumption.
1.3.8.1
Graphics
The highly compact Intel Graphics Media Adapter contains an advanced shader
architecture (model 3.0+) that performs pixel shading and vertex shading within a
single hardware accelerator. The processing of pixels is deferred until they are
determined to be visible, which minimizes access to memory and improves render
performance.
1.3.8.2
Video
The Intel® SCH supports full hardware acceleration of video decode standards, such as
H.264, MPEG2, MPEG4, VC1, and WMV9.
1.3.9
Display Interfaces
The Intel Graphics Media Adapter includes LVDS and Serial DVO display ports
permitting simultaneous independent operation of two displays, depending on Intel®
SCH component.
If external graphics is used instead of the internal graphics device, LVDS and SDVO
ports will not function.
1.3.9.1
1.3.9.2
LVDS
The Intel® SCH supports a Low-Voltage Differential Signaling interface that allows the
Intel Graphics Media Adapter to communicate directly to an on-board flat-panel display.
The LVDS interface supports pixel color depths of 18 and 24 bits.
Serial DVO (SDVO) Display
The Intel® SCH has a digital display channel capable of driving SDVO adapters that
provide interfaces to a variety of external display technologies (e.g., DVI, TV-Out,
analog CRT).
SDVO lane reversal is not supported.
