System Overview

2.3System Architecture

The systems covered in this guide feature an architecture based on the Intel Q35 Express chipset (Figure 2-13). All systems covered in this guide include the following key components:

Intel Pentium Dual-Core, Core 2 Duo, Core 2 Quad, or Celeron processor.

Intel Q35 Express chipset - Includes Q35 GMCH north bridge and 82801 ICH9-DO south bridge

SMC SCH5327 super I/O controller supporting PS/2 keyboard and mouse peripherals

AD1884 audio controller supporting line in, line out, microphone in, and headphones out

Intel 82566DM 10/100/1000 network interface controller

The Q35 chipset provides a major portion of system functionality. Designed to compliment the latest Intel processors, the Q35 GMCH integrates with the processor through a 800/1066/1333-MHz Front-Side Bus (FSB) and communicates with the ICH9-DO component through the Direct Media Interface (DMI). The integrated graphics controller of the Q35 on SFF and CMT systems can be upgraded through a PCI Express (PCIe) x16 graphics slot. All systems include a serial ATA (SATA) hard drive in the standard configuration. The USDT model supports a Slimline Optical Drive through a legacy parallel ATA 100 interface.

Table 2-2 lists the differences between models by form factor.
