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. Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component. Before you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components. 3. 4. 5. When lit, the green LED (SB_PWR1) indicates that the system is ON, in sleep mode, or in soft-off mode, a reminder that you should shut down the system and unplug the power cable before removing or plugging in any motherboard component. SB_PWR1 ® P4S533-MX P4S533-MX Onboard LED ON Standby Power OFF Powered Off Install only 1.5V AGP cards on this motherboard! 1-8 Chapter 1: Product introduction 1.7 Motherboard installation Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. The motherboard uses the micro-ATX form factor that measures 9.6 inches x 9.6 inches (24.5 cm x 24.5 cm). Make sure to unplug the power cord before installing or removing the motherboard. Failure to do so may cause you physical injury and damage motherboard components. 1.7.1 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. 1.7.2 Screw holes Place eight (8) screws into the holes indicated by circles to secure the motherboard to the chassis. Do not overtighten the screws! Doing so may damage the motherboard. Place this side towards the rear of the chassis ASUS P4S533-MX motherboard user guide 1-9 1.8 Central Processing Unit (CPU) 1.8.1 Overview The motherboard comes with a surface mount 478-pin Zero Insertion Force (ZIF) socket. The socket is designed for the Intel® Pentium® 4 Processor in the 478-pin package with 512/256KB L2 cache on 0.13 micron process. This processor supports 533/400MHz front side bus (FSB), and allows data transfer rates of 4.2GB/s and 3.2GB/s. Note in the illustration that the CPU has a gold triangular mark on one corner. This mark indicates the processor Pin 1 that should match a specific corner of the CPU socket. Gold Mark Incorrect installation of the CPU into the socket may bend the pins and severely damage the CPU! Notes on Intel® Hyper-Threading Technology 1. 2. This motherboard supports Intel Pentium 4 CPUs with Hyper-Threading Technology. (since PCB R2.00 or later versions) Hyper-Threading Technology is supported under Windows XP and Linux 2.4.x (kernel) and later versions only. Under Linux, use the Hyper-Threading compliler to compile the code. If you are using any other operating systems, disable the Hyper-Threading Techonology item in BIOS to ensure system stability and performance. It is recommended that you install WinXP Service Pack 1. 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. 3. 4. 5. To use the Hyper-Threading Technology on this motherboard: 1. Buy an Intel Pentium 4 CPU that supports Hyper-Threading Technology. Install the CPU. 2. Power up the system and enter BIOS Setup (see Chapter 2). Under the Boot Menu, make sure that the item Hyper-Threading Technology is set to Enabled. The item appears only if you installed a CPU that supports HyperThreading Techonology. 3. Reboot the computer. 1-10 Chapter 1: Product introduction
