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.
