System Overview

2.3System Architecture

The systems covered in this guide feature an architecture based on the Intel Celeron, Pentium and Intel Core i3/i5/17 processors and the Intel Q67 Express Platform Controller Hub (PCH) shown in Figure 2-2. All systems covered in this guide include the following key components:

■Intel Pentium processor or Intel Core i3/i5/i7 processor

■Intel Q67 Express PCH-DO chipset

■Super I/O (SIO) controller supporting PS/2 keyboard and mouse peripherals

■ALC261 audio controller supporting line in, line out, microphone in, and headphones out

■Intel 82579LM GbE network interface controller

■HP ProtectTools Embedded Security

The Q67 Express PCH provides a major portion of system functionality. Designed to complement 2nd generation Intel Core processors, the Q67 Express PCH communicates with the processor through the Flexible Display Interface (FDI) and the Direct Media Interface (DMI). All systems include a serial ATA (SATA) hard drive in the standard configuration.
