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.

Make sure that the Ring Resume From Soft Off option is set to Enabled in the BIOS setup section (Refer to the Power Management section in Chapter 4.) Alarm Wake Up If you want to autoboot the system at a certain time, set the function of RTC Alarm time properly and the function of RTC Alarm Resume From Soft Off option in the BIOS Setup section will be set to Enabled. 16 Chapter 3 JP11 (21, 22) (PWB) ­ 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: 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. 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, you need to clear CMOS for a moment then set back to Normal Mode or hold down the key then power on to reboot the system. 18 Chapter 3 Entering BIOS Setup To enter the BIOS 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: 2. AMIBIOS SIMPLE SETUP UTILITY - VERSION 1.1X (C)1998 American megatrends, Inc.
