Unpacking the Mainboard & StaticElectricity Precautions

This Mainboard package contains the following items:

1. This Mainboard

2. The Device Driver for this mainboard

3. This UserÕs Guide

4. Sound & Game ribbon cables/bracket

5. ATX Form Card (optional)

The mainboard is easily damaged by static electricity.Follow the precautions below while unpacking orinstalling the mainboard.

1. Do not remove the mainboard from its originalpackage until you are ready to install it.

2. Frequently ground yourself to discharge any staticelectric charge that may build up in your bodywhile working on installation and/orconfiguration. For example, you may groundyourself by grasping an unpainted portion of thesystemÕs metal chassis.

3. Remove the mainboard from its anti-staticpackaging and place it on a grounded surface,component side up.

4. Handle the mainboard by its edges or by themounting bracket to avoid touching itscomponents.

5. Check the mainboard for damage. If any integratedcircuit appears loose, press carefully to seat itfirmly in its socket.

6. Do not apply power if the mainboard appearsdamaged. If there is damage to the board contactyour dealer immediately.

The functions and connectors described below workwith the ATX power supply.

Software Power-Off

Follow the steps below to use the ÒSoftware Power-OffControlÓ function in Windows 95 with ATX powersupply.

1. Click the START button on the Windows 95 taskbar.

2. Select Shut Down The Computer to turn off thecomputer. The message ÒIt is now safe to turn offyour computer.Ó will not be shown when using thisfunction.

Modem Ring Power-On

While in Soft-off/Suspend state, if an external modemring-up signal occurs, the system wakes up and can beremotely accessed. Make sure that the Ring ResumeFrom Soft Off option is set to Enabled in the BIOS setupsection (Refer to the Power Management section inChapter 4.)

Alarm Wake Up

If you want to autoboot the system at a certain time, setthe function of RTC Alarm time properly and thefunction of RTC Alarm Resume From Soft Off option inthe BIOS Setup section will be set to Enabled.

ATX Functions & Connectors 17

J11 (21, 22) (SUS–SW) – ATX Power Button and SuspendSwitch Connector

Attach the ATX Power Button or Suspend Switch cableto this connector.

In the AT power system, this connector will act as asuspend switch; and in the ATX power system, thisconnector will be not only an ATX power button but aSuspend switch as well. Details are described below:

When the system is off, push the power button to turnthe system on. When the system is on, push the powerbutton rapidly to switch the system to the Suspendmode, and, by pushing and holding the button formore than 4 seconds, it will turn the system completelyoff. When the system is in the Suspend mode, push thepower button rapidly to turn the system on.

Chapter 4BIOS Setup

This chapter explains how to configure the mainboardÕsBIOS setup program. The setup program providedwith the mainboard is the BIOS from Award.

After you have configured the mainboard and haveassembled the components, turn on the computer andrun the software setup to ensure that the systeminformation is correct.

The software setup of the system board is achievedthrough Basic Input-Output System (BIOS)programming. You use the BIOS setup program to tellthe operating system what type of devices areconnected to your system board.

The system setup is also called CMOS setup. Normally,you need to run system setup if either the hardware isnot identical with information contained in the CMOSRAM, or if the CMOS RAM has lost power.

Note: Hold down the <End> key or to clear CMOS for amoment then set back to Normal Mode then power onto reboot the system when installing newer BIOS intothis mainboard .

BIOS Setup 19

Entering BIOS Setup

To enter the BIOS Setup program:

1. Turn on or reboot the system. A screen appearswith a series of diagnostic checks.

2. When ÒHit <DEL> if you want to run SETUPÓappears, press the <DEL> key to enter the BIOSsetup program. The following screen appears:
