Introduction

1.2 Special Features of the System Board

PCI Express

PCI Express is a high bandwidth I/O infrastructure that possesses the ability to scale speeds by forming multiple lanes. The system board currently supports the physical layer of x1 and x16 (915G- TMGF only) lane widths.

The x1 PCI Express lane supports transfer rate of 2.5 Gigabytes (250MBbps) per second. The PCI Express architecture also provides a high performance graphics infrastructure by doubling the capability of the existing AGP 8x designs over a x16 PCI Express lane that provides 4 Gigabytes per second transfer rate.

Intel Graphics Media Accelerator 900

The graphics flexibility of the built-in Intel® Graphics Media Accelerator (GMA) 900 supports enhanced 2D, 3D and video capabilities. It also support widescreen LCD displays, accelerated DirectX* 9 3D and PCI Express graphics cards.

Hyper-Threading Technology Functionality Requirements

The system board supports Intel processors with Hyper-Threading Technology. Enabling the functionality of Hyper-Threading Technology for your computer system requires ALL of the following platforms.

Components:

•CPU - an Intel® Pentium® 4 Processor with HT Technology

•Chipset - an Intel® chipset that supports HT Technology

•BIOS - a BIOS that supports HT Technology and has it enabled

•OS - an operating system that includes optimizations for HT Technology

Please refer to Appendix A for information a bout enabling the functionality of the Hyper-Threading Technology. For more information on Hyper-Threading Technology, go to: www.intel.com/info/ hyperthreading.
