This chapter describes the motherboard features and the new technologies it supports.
1.1 Special features 1.1.1 Product highlights Latest processor technology The motherboard supports AMD socket AM2 single-core Athlon 64/ Sempron and dual-core Athlon 64 X2/Athlon 64 FX processors with 2MB/1MB/512KB L2 cache, which is based on 64-bit architecture. It features 2000/1600 MT/s HyperTransport Bus, dual-channel un-buffered DDR2 800 memory support and AMD Cool ‘n’ Quiet Technology. See page 1-9 for details.
PCI Express™ interface The motherboard fully supports PCI Express, the latest I/O interconnect technology that speeds up the PCI bus. PCI Express features point‑to‑point serial interconnections between devices and allows higher clockspeeds by carrying data in packets. This high speed interface is software compatible with existing PCI specifications. See page 1-20 for details.
1.1.2 Innovative ASUS features ASUS CrashFree BIOS 2 This feature allows you to restore the original BIOS data from the support CD or floppy disk in case when the BIOS codes and data are corrupted. This protection eliminates the need to buy a replacement BIOS chip. See page 2-6 for details. ASUS EZ Flash 2 With the ASUS EZ Flash, you can easily update the system BIOS even before loading the operating system. No need to use a DOS-based utility or boot from a floppy disk. See page 2-3 for details.
1.2 Before you proceed Take note of the following precautions before you install motherboard components or change any motherboard settings. • Unplug the power cord from the wall socket before touching any component. • 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.
1.3 Motherboard overview 1.3.1 Motherboard layout 22.4cm (8.8in) EATXPWR 24.5cm (9.
1.3.2 Placement direction When installing the motherboard, make sure that you place it into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis as indicated in the image below. 1.3.3 Screw holes Place six (6) screws into the holes indicated by circles to secure the motherboard to the chassis. Do not overtighten the screws! Doing so can damage the motherboard.
1.4 Central Processing Unit (CPU) The motherboard comes with a 940-pin AM2 socket designed for the AMD Athlon™ 64 X2/Athlon™ 64/Athlon™ FX/Sempron™ processor. The AM2 socket has a different pinout from the 940-pin socket designed for the AMD Opteron™ processor. Make sure you use a CPU is designed for the AM2 socket. The CPU fits in only one correct orientation. DO NOT force the CPU into the socket to prevent bending the connectors on the socket and damaging the CPU! 1.4.
3. Position the CPU above the socket such that the CPU corner with the gold triangle matches the socket corner with a small triangle. 4. Carefully insert the CPU into the socket until it fits in place. Small triangle Gold triangle The CPU fits only in one correct orientation. DO NOT force the CPU into the socket to prevent bending the pins and damaging the CPU! 5. When the CPU is in place, push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked.
1.4.2 Installing the heatsink and fan The AMD Athlon™ 64 X2/Athlon™ 64/Athlon™ FX/Sempron™ processor require a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. Make sure that you use only qualified heatsink and fan assembly. Follow these steps to install the CPU heatsink and fan. 1. Place the heatsink on top of the installed CPU, making sure that the heatsink fits properly on the retention module base.
2. Attach one end of the retention bracket to the retention module base. 3. Align the other end of the retention bracket (near the retention bracket lock) to the retention module base. A clicking sound denotes that the retention bracket is in place. Make sure that the fan and heatsink assembly perfectly fits the retention mechanism module base; otherwise, you cannot snap the retention bracket in place. 4.
1.5 System memory 1.5.1 Overview The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory Modules (DIMM) sockets. A DDR2 module has the same physical dimensions as a DDR DIMM but has a 240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched differently to prevent installation on a DDR DIMM socket.
* For dual-channel memory configuration (2), you may: • install identical DIMMs in all four sockets OR • install an identical DIMM pair in DIMM_A1 and DIMM_B1 (yellow sockets) and another identical DIMM pair in DIMM_A2 and DIMM_B2 (black sockets) * Always use identical DDR2 DIMM pairs for dual-channel model. For optimum compatibility, we recommend that you obtain memory modules from the same vendor. Visit the ASUS website (www.asus. com) for the latest Qualified Vendors List.
1.5.3 Installing a DIMM Make sure to unplug the power supply before adding or removing DIMMs or other system components. Failure to do so may cause severe damage to both the motherboard and the components. 2 1. Unlock a DIMM socket by pressing the retaining clips outward. 2. Align a DIMM on the socket such that the notch on the DIMM matches the break on the socket. 3. 3 1 1 Firmly insert the DIMM into the socket until the retaining clips snap back in place and the DIMM is properly seated. • • 1.
1.6 Expansion slots In the future, you may need to install expansion cards. The following sub‑sections describe the slots and the expansion cards that they support. Make sure to unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components. 1.6.1 Installing an expansion card To install an expansion card: 1.

ASUS CrashFree BIOS 2 (Updates the BIOS using a bootable floppy disk, when the BIOS file fails or gets corrupted.) 4. ASUS Update (Updates the BIOS in Windows® environment.
2.1.2 ASUS EZ Flash 2 utility The ASUS EZ Flash 2 feature allows you to update the BIOS without having to go through the long process of booting from a floppy disk and using a DOS‑based utility. The EZ Flash 2 utility is built-in the BIOS chip so it is accessible by pressing + during the Power-On Self Tests (POST). To update the BIOS using EZ Flash: 1. Visit the system builder website to download the latest BIOS file for the motherboard and rename the same to M2N-MX.ROM. 2.
2.1.3 AFUDOS utility The AFUDOS utility allows you to update the BIOS file in DOS environment using a bootable floppy disk with the updated BIOS file. This utility also allows you to copy the current BIOS file that you can use as backup when the BIOS fails or gets corrupted during the updating process. Copying the current BIOS To copy the current BIOS file using the AFUDOS utility: • Make sure that the floppy disk is not write-protected and has at least 1024KB free space to save the file.
Updating the BIOS file To update the BIOS file using the AFUDOS utility: 1. Visit system builder website and download the latest BIOS file for the motherboard. Save the BIOS file to a bootable floppy disk. Write the BIOS filename on a piece of paper. You need to type the exact BIOS filename at the DOS prompt. 2. Copy the AFUDOS utility (afudos.exe) from the motherboard support CD to the bootable floppy disk you created earlier. 3.
2.1.4 ASUS CrashFree BIOS 2 utility The ASUS CrashFree BIOS 2 is an auto recovery tool that allows you to restore the BIOS file when it fails or gets corrupted during the updating process. You can update a corrupted BIOS file using the floppy disk that contains the updated BIOS file. • Prepare the floppy disk containing the updated motherboard BIOS before using this utility. • Make sure that you rename the original or updated BIOS file in the floppy disk or the USB flash disk to M2N-MX.ROM.
2.1.5 ASUS Update utility The ASUS Update is a utility that allows you to manage, save, and update the motherboard BIOS in Windows® environment. The ASUS Update utility allows you to: • Save the current BIOS file • Update the BIOS from an updated BIOS file • View the BIOS version information. This utility is available in the support CD that comes with the motherboard package. ASUS Update requires an Internet connection either through a network or an Internet Service Provider (ISP).
Updating the BIOS through a BIOS file To update the BIOS through a BIOS file: 2- 1. Launch the ASUS Update utility from the Windows® desktop by clicking Start > Programs > ASUS > ASUSUpdate > ASUSUpdate. The ASUS Update main window appears. 2. Select Update BIOS from a file option from the drop‑down menu, then click Next. 3. Locate the BIOS file from the Open window, then click Open. 4. Follow the screen instructions to complete the update process.
