1.1 Welcome! Thank you for buying an ASUS® P5L-MX/IPAT motherboard! The motherboard delivers a host of new features and latest technologies, making it another standout in the long line of ASUS quality motherboards! Before you start installing the motherboard, and hardware devices on it, check the items in your package with the list below. 1.2 Package contents Check your motherboard package for the following items.
Intel ® 945G chipset The Intel® 945G graphics memory controller hub (GMCH) and the ICH7 I/O controller hub provide the vital interfaces for the motherboard. The GMCH features the Intel® Graphics Media Accelerator 950, an integrated graphics engine for enhanced 3D, 2D, and video capabilities. The GMCH provides the interface for a processor in the 775-land package with 533/800/1066 MHz front side bus (FSB), dual channel DDR2 at speeds of up to 667 MHz, and PCI Express x16 graphics card.
1.4 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 to 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.
1.5 Motherboard overview Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. Make sure to unplug the power cord before installing or removing the motherboard. Failure to do so can cause you physical injury and damage motherboard components. 1.5.1 Placement direction When installing the motherboard, make sure that you place it into the chassis in the correct orientation.

1.6 Central Processing Unit (CPU) The motherboard comes with a surface mount LGA775 socket designed for the Intel® Core™2 Extreme/Core™2 Duo/Pentium® D/Pentium® 4 and Celeron® D processors. 1.6.1 • Your boxed Intel® Core™2 Extreme/Core™2 Duo/Pentium® D/ Pentium® 4 or Celeron® D LGA775 processor package should come with installation instructions for the CPU, fan and heatsink assembly. If the instructions in this section do not match the CPU documentation, follow the latter.
2. Press the load lever with your thumb (A) and move it to the left (B) until it is released from the retention tab. Retention tab PnP Cap A Load lever B This side of the cam box should face you. To prevent damage to the socket pins, do not remove the PnP cap unless you are installing a CPU. 3. Lift the load lever in the direction of the arrow to a 135º angle. 4.
6. Close the load plate (A), then push the load lever (B) until it snaps into the retention tab. A B 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! The motherboard supports Intel® LGA775 processors with the Intel® Enhanced Memory 64 Technology (EM64T), Enhanced Intel SpeedStep® Technology (EIST), and Hyper‑Threading Technology.
1.6.2 Installling the CPU heatsink and fan The Intel® Core™2 Extreme/Core™2 Duo/Pentium® D/Pentium® 4 and Celeron® D processors require a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. • Install the motherboard to the chassis before you install the CPU fan and heatsink assembly • When you buy a boxed Intel® Core™2 Extreme/Core™2 Duo/ Pentium® D/Pentium® 4 or Celeron® D LGA775 processor, the packageincludes the CPU fan and heatsink assembly.
2. 3. Push down two fasteners at a time in a diagonal sequence to secure the heatsink and fan assembly in place. A B B A B A A B When the fan and heatsink assembly is in place, connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN.

Hardware monitoring errors can occur if you fail to plug this connector.
1.6.3 Uninstalling the CPU heatsink and fan To uninstall the CPU heatsink and fan: 1-12 1. Disconnect the CPU fan cable from the connector on the motherboard. 2. Rotate each fastener counterclockwise. 3. Pull up two fasteners at a time in a diagonal sequence to disengage the heatsink and fan assembly from the motherboard.
4. Remove the heatsink and fan assembly from the motherboard. 5. Rotate each fastener clockwise to reset the orientation. Narrow end of the groove The narrow end of the groove should point outward after resetting. (The photo shows the groove shaded for emphasis.
1.7 System memory 1.7.1 Overview The motherboard comes with two 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. 128 Pins P5L-MX/IPAT 112 Pins DIMM_A1 DIMM_B1 The figure illustrates the location of the DDR2 DIMM sockets: R P5L-MX/IPAT 240-pin DDR2 DIMM Sockets 1.7.
Important notice on installing Windows® XP 32-bit version If you install Windows® XP 32-bit version Operating System (OS), the limitation of this OS version is that it may reserve a certain amount of memory space for system devices. We recommend that you install less than 3 GB system memory if you would like to work under Windows® XP 32-bit version OS. The excess memory installation will not cause any usage problem, but it will not give users the benefit of manipulating this excess memory space.
1.7.3 DDR2 Qualified Vendors List The following table lists the memory modules that have been tested and qualified for use with this motherboard. Visit the ASUS website (www.asus. com) for the latest DDR2 DIMM modules for this motherboard.

This chapter tells how to change the system settings through the BIOS Setup menus. Detailed descriptions of the BIOS parameters are also provided.
2.1 Managing and updating your BIOS The following utilities allow you to manage and update the motherboard Basic Input/Output System (BIOS) setup. 1. ASUS AFUDOS (Updates the BIOS in DOS mode using a bootable floppy disk.) 2. ASUS AFUWIN (Updates the BIOS in Windows® environment.) Refer to the corresponding sections for details on these utilities. Save a copy of the original motherboard BIOS file to a bootable floppy disk in case you need to restore the BIOS in the future.
2.1.2 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 the ASUS website (www.asus.com) 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.
2.1.3 AFUWIN utility The AFUWIN utility allows you to update the BIOS file in a Windows® environment. To update the BIOS using AFUWIN: 1. Download the latest BIOS file for your motherboard from the ASUS website (www.asus.com) and save the BIOS file to a new folder. Write the BIOS filename on a piece of paper. You need to type the exact BIOS filename at the DOS prompt later. 2. Copy the AFUWIN utilities (Afwin.exe and AMIFLDrv.
