Chapter 1 Introduction

The Server board, SMB-2501, of RS-400-SF is an

ATX size Pentium 4 motherboard designed for high-density

Internet services, CT and industrial automation. The

serverboard uses a high integrated core logic chipset,

SIS650 chipset with a high performance host interface for

Intel Pentium 4 processor, a high performance 2D/3D

Graphic Engine, a high performance memory controller and

an AGP 4X interface. The SiS 650 integrated a high

performance 2D/3D Graphic Engine, Video Accelerator and

Advanced Hardware Acceleration MPEGI/MPEGII Video

Decoder for the Intel Pentium 4 series based PC systems. It

also integrates a high performance 2.1GB/s DDR266

Memory controller to sustain the bandwidth demand from

the integrated GUI or external AGP master, host processor,

as well as the multi I/O masters. In addition to integrated

GUI, SiS650 also can support external AGP slot with AGP

4X capability and Fast Write Transactions. The SiS650

adopts the Shared Memory Architecture, eliminating the

need and thus the cost of the frame buffer memory by

organizing the frame buffer in the system memory. The

frame buffer size can be allocated from 8MB to 64MB. The

Integrated GUI features a high performance 3D accelerator

with 2 Pixel / 4 Texture, and a 128 bit 2D accelerator with
