Unpacking the Mainboard & StaticElectricity Precautions
This Mainboard package contains the following items:
1. This Mainboard and a Device Driver
2. This UserÕs Guide and AT cable set
3. Sound & Game ribbon cables/bracket andSPDIF/IN cable
4. ATX Form Card and VGA cable/bracket
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.

Memory Installation
The mainboard lets you add up to 384MB of systemmemory through SIMM and DIMM sockets on theboard. Two SIMM sockets and two 168-pin DIMMsockets are divided into three banks: Bank 0, Bank 1,and Bank 2. The mainboard supports the followingmemory configurations.
Bank Memory ModuleBank 0DIMM1
4MB, 8MB, 16MB, 32MB, 64MB, 128MB, 256MB
Bank 1DIMM2 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, 256MB
Bank 2SIMM1 & SIMM2 2 x 4MB/8MB/16MB/32MB/64MB/128MB
Total System Memory = Bank 0 + Bank 1 + Bank 2Notes: 1. The speed of SDRAM DIMM modules have to be faster than
12ns (Ò-12Ó parts). When 100MHz clock speed is beingused, then the speed of SDRAM DIMM should meet thePC100 SDRAM specification (8ns or Ò-8Ó SDRAM atleast).
2. The speed of EDO/FPM DRAM have to be faster than 70ns,but it is not recommended for the performance purpose of thesystem.
Chapter 3ACPI Functions & Connectors
with ATX Power
PWR2 – ATX Power Connector
The ATX power supply provides a single 20-pinconnector and supports the ACPI specification.
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 15
J8 (19, 20) (PWBT) – 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 AMI.
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: When installing newer BIOS into thismainboard, you need to clear CMOS for amoment then set back to Normal Mode or holddown the <End> key then power on to rebootthe system.
BIOS Setup 17
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:
