2.4 System Architecture

The systems covered in this guide feature an architecture based on the Intel Q965 Express
chipset (Figure 2-13). All systems covered in this guide include the following key components:
■
Intel Pentium 4, Pentium D, or Core 2 Duo processor.
■
Intel Q965 Express chipset - Includes Q965 GMCH north bridge and 82801 ICH8-DO south
bridge
■
SMC SCH5317 super I/O controller supporting PS/2 keyboard and mouse peripherals
■
ALC262 audio controller supporting line in, line out, microphone in, and headphones out
■
Intel 82566DM 10/100/1000 network interface controller
The Q965 chipset provides a major portion of system functionality. Designed to compliment the
latest Intel processors, the Q965 GMCH intefaces with the processor through a
533/800/1066-MB Front-Side Bus (FSB) and communicates with the ICH8-DO component
through the Direct Media Interface (DMI). The integrated graphics controller of the Q965 may
be upgraded through a PCI Express x16 graphics slot. All systems include at least one PCI 2.3
slot and feature as standard a serial ATA (SATA) hard drive. The USDT model supports a
Slimline Optical Drive through a legacy parallel ATA 100 interface.
Table 2-3 lists the differences between models by form factor.
