Basic installation

Preparation
Before you proceed, make sure that you have all the components you plan to install in the system.
Basic components to install
1. 2. 3. 4. 5. Central processing unit (CPU) DDR Dual Inline Memory Module (DIMM) Expansion card(s) Hard disk drive Optical drive

Before you proceed

Take note of the following precautions before you install components into the system.
Use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity. Hold components by the edges to avoid touching the ICs on them. Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.
The system motherboard comes with an onboard standby power LED. This LED lights up to indicate that the system is ON, in sleep mode or in soft-off mode, and not powered OFF. Unplug the power cable from the power outlet and make sure that the standby power LED is OFF before installing any system component.

Removing the system cover
2. Remove the cover screws. Keep the screws for later use.
To remove the cover and metal chassis support: On the rear panel, locate the two thumb screws that secure the cover to the chassis.
Slightly pull the cover toward the rear panel until the cover hooks disengages from the chassis holes.
Lift the system cover, then set aside.
Lift the expansion card lock to a 90-100 angle.
Lift the chassis support bracket to a 45 angle, then carefully pull to release. Set the chassis support bracket aside.

Removing the front panel assembly
To remove the front panel assembly: Place the system vertically. Locate the front panel assembly hooks. Pull the hooks outward to release the front panel assembly.
Swing the left edge of the front panel assembly outward. Unhook the hinge-like tabs from the holes on the right side of the chassis to detach.

Hinge-like tab

Do not use too much force when removing the front panel assembly.

Installing a CPU

The ASUS motherboard comes with a surface mount LGA775 socket designed for the Intel Pentium 4 processor in the 775-land package.
Removing the CPU fan and heatsink assembly
The system package includes a pre-installed proprietary CPU fan and heatsink assembly to ensure optimum thermal condition and performance.
D O N O T replace the proprietary CPU fan and heatsink with other models.
To uninstall the CPU heatsink and fan: 1. Disconnect the CPU fan cable from the CPU fan connector on the motherboard.

Rotate each fastener counterclockwise.
Pull up two fasteners at a time in a diagonal sequence to disengage the heatsink and fan assembly from the motherboard. Carefully remove the heatsink and fan assembly from the motherboard. Rotate each fastener clockwise to ensure correct orientation when reinstalling.

CPU installation

Your boxed Intel Pentium 4 LGA775 processor package should come with installation instructions for the CPU, heatsink, and the retention mechanism. If the instructions in this section do not match the CPU documentation, follow the latter. Check your motherboard to make sure that the socket contacts are not bent. Contact your retailer immediately if you see any damage to the socket contacts/motherboard components. ASUS will shoulder the cost of repair only if the damage is shipment/ transit-related. The product warranty does not cover damage to the socket contacts resulting from incorrect CPU installation or removal.

Installing the CPU

To install a CPU: 1. Locate the CPU socket on the motherboard. 2. Press the load lever with your thumb (A), then move it to the left (B) until it is released from the retention tab.

Retention tab

Load lever
Lift the load lever in the direction of the arrow to a 135 angle.
Lift the load plate with your thumb and forefinger to a 100 angle.
Position the CPU over the socket, making sure that the gold triangle is on the bottom-left corner of the socket. The socket alignment key should fit into the CPU notch.

Alignment key

Close the load plate.
Push the load lever until it snaps into the retention tab.
The motherboard supports Intel Pentium 4 LGA775 processors with the Intel Enhanced Memory 64 Technology (EM64T), Enhanced Intel SpeedStep Technology (EIST), and Hyper-Threading Technology. Refer to the Appendix for more information on these CPU features.
Reinstalling the CPU fan and heatsink assembly
To reinstall the CPU fan and heatsink assembly: 1. Place the heatsink on top of the installed CPU, making sure that the four fasteners match the holes on the motherboard.
Orient the heatsink and fan assembly such that the CPU fan cable is closest to the CPU fan connector.

Appendix

The Appendix describes the CPU features and technologies that the system supports.

Intel EM64T

The motherboard is fully compatible with Intel Pentium 4 LGA775 processors running on 32-bit operating systems. The motherboard comes with a BIOS file that supports EM64T. You can download the latest BIOS file from the ASUS website (www.asus.com/support/download/) if you need to update the BIOS file. See Chapter 5 for details. Visit www.intel.com for more information on the EM64T feature. Visit www.microsoft.com for more information on Windows 64-bit OS.
Using the Intel EM64T feature
To use the Intel EM64T feature: 1. 2. 3. 4. Install an Intel Pentium 4 CPU that supports the Intel EM64T. Install a 64-bit operating system (Windows XP Professional x64 Edition or Windows Server 2003 x64 Edition). Install the 64-bit drivers for the motherboard components and devices from the support CD. Install the 64-bit drivers for expansion cards or add-on devices, if any.
Refer to the expansion card or add-on device(s) documentation, or visit the related website, to verify if the card/device supports a 64-bit system.

Enhanced Intel SpeedStep Technology (EIST)
The motherboard comes with a BIOS file that supports EIST. You can download the latest BIOS file from the ASUS website (www.asus.com/support/download/) if you need to update the BIOS. See Chapter 5 for details. Visit www.intel.com for more information on the EIST feature.

System requirements

Before using EIST, check your system if it meets the following requirements: Intel Pentium 4 processor with EIST support BIOS file with EIST support Operating system with EIST support (Windows XP SP2/Windows Server 2003 SP1/Linux 2.6 kernel or later versions)

1. 2. 3. 4. 5. 6.

Using the EIST
To use the EIST feature: Turn on the computer, then enter the BIOS Setup. Go to the Advanced Menu highlight CPU Configuration Menu, Configuration, then press <Enter>. Set the Intel(R) SpeedStep Technology item to [Automatic], then press <Enter>. See page 5-15 for details. Press <F10> to save your changes and exit the BIOS setup. After the computer restarts, right click on a blank space on the desktop, then select Properties from the pop-up menu. When the Display Properties window appears, click the Screen Saver tab. Click the Power button on the Monitor power section to open the Power Options Properties window.
On the Power schemes section, click , then select any option except Home/Office Desktop or Always On On. Click A p p l y then click O K y, K.
10. Close the Display Properties window. After you adjust the power scheme, the CPU internal frequency slightly decreases when the CPU loading is low.
The screen displays and procedures may vary depending on the operating system.
Intel Hyper-Threading Technology
The motherboard supports Intel Pentium 4 LGA775 processors with Hyper-Threading Technology. Hyper-Threading Technology is supported under Windows XP/2003 Server and Linux 2.4.x (kernel) and later versions only. Under Linux, use the Hyper-Threading compiler to compile the code. If you are using any other operating systems, disable the Hyper-Threading Techonology item in the BIOS to ensure system stability and performance. Installing Windows XP Service Pack 1 or later version is recommended. Make sure to enable the Hyper-Threading Technology item in BIOS before installing a supported operating system. For more information on Hyper-Threading Technology, visit www.intel.com/info/hyperthreading.
