Use the COM port to connect serial devices such as mice or fax/modems.
Installing the Processor This motherboard has a Socket 462 processor socket. When choosing a processor, consider the performance requirements of the system. Performance is based on the processor design, the clock speed and system bus frequency of the processor, and the quantity of internal cache memory and external cache memory. CPU Installation Procedure Follow these instructions to install the CPU: Pin 1 Socket-462 CPU_FAN1 1 1. Unhook the locking lever of the CPU socket.
Installing Memory Modules This motherboard accommodates two 184-pin 2.5V unbuffered Double Data Rate SDRAM (DDR SDRAM) Dual Inline Memory Module (DIMM) sockets, and supports up to 2.0 GB of DDR400 SDRAM with KM400A NB or DDR333 SDRAM with KM400 NB. DIM1 DIM2 Installation Procedure These modules can be installed with up to 2 GB system memory. Following these steps to install the memory module. 1. Push down the latches on both sides of the DIMM socket. 2. Align the memory module with the socket.
Jumper Settings Using a jumper cap to connect two pins is SHORT, removing it from these pins, OPEN. 1 JP3 1 CLEAR_CMOS1 Jumper CLEAR_CMOS1: Clear CMOS Memory Use this jumper to clear the contents of the CMOS memory. You may need to clear the CMOS memory if the settings in the Setup Utility are incorrect and prevent your motherboard from operating. To clear the CMOS memory, disconnect all the power cables from the motherboard and then move the jumper cap into the CLEAR setting for a few seconds.
Jumper JP3: CPU Clock Selector This jumper selects the processor clock frequency.

Please check the pin assignment of the cable and the USB header on the motherboard. Make sure the pin assignment will match before plugging in. Any incorrect usage may cause unexpected damage to the system. The vendor won’t be responsible for any incidental or consequential damage arising from the usage or misusage of the purchased product.
Floppy Disk Drive The motherboard ships with a floppy disk drive cable that can support one or two drives. Drives can be 3.5” or 5.25” wide, with capacities of 360K, 720K, 1.2MB, 1.44MB, or 2.88MB. Install your drives and connect power from the system power supply. Use the cable provided to connect the drives to the floppy disk drive connector FDC1. IDE Devices IDE devices include hard disk drives, high-density diskette drives, and CD-ROM or DVD-ROM drives, among others.
The SATA connector supports new Serial ATA devices for the highest data transfer rates (1.5 Gbps burst), simpler disk drive cabling and easier PC assembly. It eliminates limitations of the current Parallel ATA interface, but maintains register compatibility and software compatibility with Parallel ATA. Internal Sound Connections If you have installed a CD-ROM drive or DVD-ROM drive, you can connect the drive audio cable to the onboard sound system.

Locate the AGP, PCI or CNR slot on the motherboard. 2. Remove the slot cover from the system chassis. 3. Insert the expansion card edge connector into the slot and press it firmly down until fully inserted. 4. Secure the expansion card bracket in the system chassis with a screw.
approved CNR card in your area and install it directly into the CNR slot.
Chapter 3 BIOS Setup Utility Introduction The BIOS Setup Utility records settings and information about your computer such as the date and time, the kind of hardware installed, and various configuration settings. Your computer uses this information to initialize all the components when booting up and functions as the basis for coordination between system components. If the Setup Utility configuration is incorrect, it may cause the system to malfunction. It can even stop your computer from booting properly.
Running the Setup Utility Each time your computer starts, before the operating system loads, a message appears on the screen that prompts you to “Hit if you want to run SETUP”. When you see this message, press the Delete key and the Main menu page of the Setup Utility appears on your monitor. AMIBIOS SIMPLE SETUP UTILITY – VERSION 1.21.13 (C) 2000 American Megatrends, Inc.
Standard CMOS Setup Page This page sets up basic information such as the date, the time, the IDE devices, and the diskette drives. If you press the F3 key, the system will automatically detect and configure the hard disks on the IDE channels. AMIBIOS SETUP – STANDARD CMOS SETUP (C) 2000 American Megatrends, Inc.
