Hardware Setup Chapter 2. Hardware Setup Hardware Setup This chapter tells you how to install the CPU, memory modules, and expansion cards, as well as how to setup the jump- ers on the mainboard. Also, it provides the instructions on connecting the peripheral devices, such as the mouse, keyboard, etc.
Hardware Setup Central Processing Unit: CPU The mainboard supports Intel Pentium 4 Northwood/Prescott proc- ® ® essor in the 478 pin package. The mainboard uses a CPU socket called PGA478 for easy CPU installation. When you are installing the CPU, make sure the CPU has a heat sink and a cooling fan attached on the top to prevent overheating.
MS-7042 M-ATX Mainboard CPU Installation Procedures for Socket 478 Please turn off the power and Open Lever unplug the power cord before installing the CPU. Sliding 90 degree Plate Pull the lever sideways away from the socket. Make sure to raise the lever up to a 90- degree angle.
Hardware Setup Installing the CPU Fan As processor technology pushes to faster speeds and higher performance, thermal management becomes increasingly important. To dissipate heat, you need to attach the CPU cooling fan and heatsink on top of the CPU. Follow the instructions below to install the Heatsink/Fan: 1.
