ATI Radeon® XPRESS 200/ULI M1573 chipset

The ATI Radeon® XPRESS 200 Northbridge provide the vital interfaces for the motherboard. The ATI Radeon® XPRESS 200 Northbridge integrates the Integrated Radeon XPRESS 200 based graphics, an integrated graphics processing unit (GPU) for enhanced 3D, 2D, and video capabilities. The Northbridge also provides the interface for a processor in the 775-land package with 533/800/1066 MHz front side bus (FSB), single channel DDR memory, a PCI Express x1 slots, and a PCI Express x16 slot for discrete graphics card.

The ULI M1573 Southbridge represents the sixth generation I/O controller hub that provides the interface for PCI Express and 6-channel high definition audio.

Enhanced Intel SpeedStep® Technology (EIST)

The Enhanced Intel SpeedStep® Technology (EIST) intelligently manages the CPU resources by automatically adjusting the CPU voltage and core frequency depending on the CPU loading and system speed or power requirement.

See page 4-25 and the Appendix for details.

PCI Express™ interface

The motherboard fully supports PCI Express, the latest I/O interconnect technology that speeds up the PCI bus. PCI Express features point-to-point serial interconnections between devices and allows higher clockspeeds by carrying data in packets. This high speed interface is software compatible with existing PCI specifications.

6-channel audio

The motherboard comes with the ADI AD1986A audio CODEC that provides 6-channel audio, audio jack-sensing and enumeration technology, and S/PDIF out support. See page 1-26 for details.

Serial ATA technology

The motherboard supports the Serial ATA technology through the Serial ATA interfaces and the ULI M1573 Southbridge. The SATA specification allows for thinner, more flexible cables with lower pin count, reduced voltage requirement, and up to 150 MB/s data transfer rate. See page 2-28 for details.

SATA RAID solution

Onboard RAID controllers provide the motherboard with RAID functionality. The ULI M1573 Southbridge allows RAID 0, RAID 1, RAID 0+1, and JBOD configuration.
