System Overview 2.3 System Architecture The systems covered in this guide feature an architecture based on the Intel Q45 Express chipset (Figure 2-2). 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 Q45 Express chipset - Includes Q45 GMCH and 82801 ICH10-DO ■ 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 82567LM GbE network interface controller ■ HP ProtectTools Embedded Security The Q45 chipset provides a major portion of system functionality. Designed to complement the latest Intel processors, the Q45 GMCH integrates with the processor through a 800/1066/1333-MHz Front-Side Bus (FSB) and communicates with the ICH10-DO component through the Direct Media Interface (DMI). The integrated graphics controller of the Q45 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. Table 2-2 lists the differences between models by form factor. Table 2-2.
