The Device Driver for this mainboard ATX FORM CARD (optional) Sound & Game ribbon cables/bracket This mainboard is easily damaged by static electricity. Follow the precautions below while unpacking or installing the mainboard. 1. Do not remove the mainboard from its original package until you are ready to install it. Before handling the mainboard, ground yourself by grasping an unpainted portion of the systemÕs metal chassis. 2. Introduction 3. 5 Frequently ground yourself to discharge any static electric charge that may build up in your body while working on installation and/or configuration. 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. 4. 5. 6. 7.

Four SIMM sockets on the mainboard are divided into two banks: Bank 0 and Bank 1. Each bank consists of two 72-pin SIMM modules, and three 168pin DIMM sockets are divided into three banks: Bank 0, Bank 1, and Bank 2. The mainboard supports the following memory configurations. Bank Memory Module Bank 0 SIMM1 & SIMM2 2 x 4MB/8MB/16MB/32MB/64MB (72-pin SIMM) or DIMM1 4MB, 8MB, 16MB, 32MB, 64MB, 128MB (168-pin DIMM) Bank 1 SIMM3 & SIMM4 2 x 4MB/8MB/16MB/32MB/64MB (72-pin SIMM) or DIMM2 4MB, 8MB, 16MB, 32MB, 64MB, 128MB (168-pin DIMM) Bank 2 DIMM3 4MB, 8MB, 16MB, 32MB (168-pin DIMM) Total System Memory = Bank 0 + Bank 1 + Bank 2 Notes: 1. SIMM3 & 4 and DIMM2, or, SIMM1 & 2 and DIMM1, these two types of DRAM module can not be used at the same time. 2. The speed of all SIMMs and DIMM modules have to be faster than 70ns. 3. Use 2 DRAM types: Fast Page Mode or Extend DATA Out (EDO) for SIMM socket. 4. Use 3 DRAM types: Fast Page Mode, Extend Data Out (EDO), or synchronous DRAM (SDRAM) for DIMM socket. 5. The function of Bank 2 will not be available while using the 64 Mbit type of SDRAM in any DIMM slots.

JP9 (PWR-BT) ­ ATX Power Button and Suspend Switch Connector Attach the ATX Power Button or Suspend Switch cable to this connector. In the AT power system, this connector will act as a suspend switch; and in the ATX power system, this connector will be not only an ATX power button but a Suspend switch as well. Details are described below: ATX Functions & Connectors 19 When the system is off, push the power button to turn the system on. When the system is on, push the power button rapidly to switch the system to the Suspend mode, and, by pushing and holding the button for more than 4 seconds, it will turn the system completely off. When the system is in the Suspend mode, push the power button rapidly to turn the system on. JP3 (WOL CONN) ­ Wake On LAN Connector While in Soft-off/Suspend state, if an external LAN signal occurs, the system wakes up and can be accessed with the LAN card. Pin 1 2 3 Description 5V Stand By Ground Active Low Chapter 4 BIOS Setup This chapter explains how to configure the mainboardÕs BIOS setup program. The setup program provided with the mainboard is the BIOS from AMI. After you have configured the mainboard and have assembled the components, turn on the computer and run the software setup to ensure that the system information is correct. The software setup of the system board is achieved through Basic Input-Output System (BIOS) programming. You use the BIOS setup program to tell the operating system what type of devices are connected to your system board. The system setup is also called CMOS setup. Normally, you need to run system setup if either the hardware is not identical with information contained in the CMOS RAM, or if the CMOS RAM has lost power. Note: When installing newer BIOS into this mainboard, J5 must be set to clear CMOS position for a moment then set back to Normal Mode or hold down the key then power on to reboot the system. BIOS Setup 21 Entering WinBIOS Setup To enter the WinBIOS Setup program: 1. Turn on or reboot the system. A screen appears with a series of diagnostic checks. When ÒHit if you want to run SETUPÓ appears, press the key to enter the BIOS setup program. The following screen appears: AMIBIOS Setup, Version 2.5 (C) 1997, American Megatrends Inc. Security 2.
