This Mainboard and a Device Driver This UserÕs Guide and AT cable set Sound & Game ribbon cables/bracket and SPDIF/IN cable ATX Form Card The mainboard is easily damaged by static electricity. Follow the precautions below while unpacking or installing the mainboard. 1. 2. Do not remove the mainboard from its original package until you are ready to install it. Frequently ground yourself to discharge any static electric charge that may build up in your body while working on installation and/or configuration. For example, you may ground yourself by grasping an unpainted portion of the systemÕs metal chassis. Remove the mainboard from its anti-static packaging and place it on a grounded surface, component side up. Handle the mainboard by its edges or by the mounting bracket to avoid touching its components. Check the mainboard for damage. If any integrated circuit appears loose, press carefully to seat it firmly in its socket. Do not apply power if the mainboard appears damaged. If there is damage to the board contact your dealer immediately. 3. 4. 5. 6. Chapter 2 Hardware Configuration Before you install this mainboard into the system chassis, you may find it convenient to first configure the mainboardÕs hardware. This chapter describes how to set jumpers and install memory modules, and where to attach components.

Memory Installation The mainboard lets you add up to 768MB of system memory through three DIMM sockets on the board, and system memory are divided into three banks: Bank 0, Bank 1, and Bank 2. The mainboard supports the following memory configurations. Bank Bank 0 DIMM1 Bank 1 DIMM2 Bank 2 DIMM3 Memory Module 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, 256MB 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, 256MB 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, 256MB Total System Memory = Bank 0 + Bank 1 + Bank 2 Notes: 1. The speed of SDRAM DIMM modules have to be faster than 12ns (ÒÐ12Ó parts). When 100MHz clock speed is being used, then the speed of SDRAM DIMM should meet the PC100 SDRAM specification (8ns or ÒÐ8Ó SDRAM at least). 2. The speed of EDO/FPM DRAM have to be faster than 70ns, but it is not recommended for the performance purpose of the system. 12 Chapter 2 Jumper Settings JP6 ­ CMOS RAM Clear Selector Description Normal Mode (default) Clear CMOS 3 Setting 1 3 1 Note: 1. Make sure that this jumper is set to Normal Mode before installing the mainboard and the power is off before clearing the CMOS. 2.
