Please review each of the following procedures before installing the motherboard. Before You Install this Motherboard Before placing and fastening the motherboard into a case you must first install a CPU and system memory modules. Please read the sections below and follow the instructions carefully.
Selecting a Processor This motherboard supports all Intel Pentium 4 processors. The motherboard’s BIOS automatically detect the required settings and configure the CMOS Setup Utility. Installing the Processor It is important to review all of the instructions before beginning the installation procedure. Carefully handle the processor by its edges, and take all precautions against electrostatic discharge. The boxed Intel Pentium 4 processor comes with a Heatsink and Thermal Interface Material applicator.
2. Position the CPU above the socket such that its marked corner matches the base of the socket lever. 3. Press it firmly on the socket while you push down the socket lever to secure the CPU.
4. After installing the CPU you may need to apply the Thermal Interface Material (TIM) to the top of the installed CPU (Fig. 2). The TIM is supplied in an applicator with the boxed Pentium 4 processors. The TIM secures the Fan/Heatsink to the CPU. However, if the Fan/Heatsink already has a patch of TIM on its underside, you won’t need to apply additional TIM to the CPU (Fig. 1).
Installing the Fan/ Heatsink To install the Fan/Heatsink assembly: 5. When installing the Fan/Heatsink and clip assembly it is important to make sure the Fan/Heatsink does not rotate or twist on the processor. Securing the Fan/ Heatsink while closing the clip lever will ensure the thermal interface material (TIM) is not damaged and the processor will operate correctly. The TIM is attached to the heatsink. 6. Make sure to close the clip levers one at a time.
7. Align the Heatsink and clip assembly with the Retention Mechanism and place it on the processor. The Heatsink is symmetrical. 8. With the clip levers in the up position (E), push down on all four clip frame corners to secure to the Retention Mechanism hooks (F). Close the clip levers (G). The levers require force to be completely closed. Connect the processor fan cable connector to the motherboard header.

Completing System Configuration After installing the motherboard in the system housing, you can connect or install the internal devices you need to complete the system. This will include attaching disk drives and connecting housing power supply connectors.
4: BIOS Setup After you have installed the motherboard and assembled the system hardware, you can power up the system. The motherboard uses the most recent Award BIOS CMOS chip. The ROM setup instructions for configuring the motherboard’s BIOS (Basic Input Output System) are contained on this chip. The CMOS Setup program lets you set system parameters, which are stored in nonvolatile CMOS RAM. This information is retained by battery backup when the system is powered off.
Entering Setup Each time the system is turned on, the BIOS performs Power-On Self Test (POST) routines. These routines run through a series of diagnostic checks. If an error occurs, it is reported in one of two ways: 1. A series of beeps, if the error is encountered before the display is initialized. 2. An error message is shown on the screen, if the display is initialized.
Standard CMOS Features The Standard CMOS Features screen lets you reset time and date settings to suit your location. The IDE devices are Auto Detected, but you can change these settings manually if necessary. The floppy drive settings and other settings are standard defaults that you can also change if necessary. Advanced BIOS Features The Advanced BIOS Features screen configures boot options such as boot devices, boot order, various boot configurations and other power functions.
Advanced Chipset Features The Advanced Chipset Features screen configures the chipset, BIOS caching and the AGP. Unless you fully understand the function of these settings, it is recommended that you do not change the default settings. Integrated Peripherals Screen The Integrated Peripherals screen configures the peripheral features integrated onto the motherboard. The settings on this screen are all optimized defaults. The IDE settings are Auto Detected and the port settings are standard settings.
Power Management Setup Screen The Power Management Setup screen configures power management settings. The settings on this screen are all optimized defaults.
