Plug in the CPU fan cable to the 3-pin CPU FAN connector and housing fan cable to the Housing Fan

connector.

1. Pull up the CPU socket level and up to

90-degree angle.

2. Locate Pin 1 in the socket and look for a

(golden) cut edge on the CPU upper interface.

Match Pin 1 and cut edge. Then insert the

CPU into the socket.

3. Press down the CPU socket level and finish

CPU installation.

Note: If you do not match the CP

socket Pin 1 and CPU cut edge

well, it may damage the CPU.

When you are using SINGLE Intel®Pentium!!! CPU with DX3R Plus-U/DX3R-U, you

must plug the jumper cap to the pin1-2 and install the CPU terminator to the

unoccu

ied socket.

This motherboard has four 168-pin DIMM sockets that allow you to install PC100 o

PC133 Registered memory up to 4.0GB.

5. Install DIMM Modules

4. JP10 CPU Terminator Jumper

3. Installing Thermal Sensor

The Thermal Sensor Connector (CN7 & CN25) provides you to use the thermal senso

to detect the temperature of the components on the motherboard.

7. Connecting Redundant SPS Connector

10. JP6 SCSI Channel Terminator Control

This motherboard implements Redundant SPS connector to provide better expansibility

on superior server. It is feasible to install an additional 337-watts power supply module

(optional) in a hot-swappable redundant configuration, which enables a fully-configure

system to continue running even if one power module fails.

The JP6 allows you to enable or disable the on-board SCSI terminator control function.

11. Connecting Front Panel Connector

ttaching such as power LED, reset switch, power switch connector, etc.… to

corresponding pins.

12. WOL (Wake on LAN) Connector

To use Wake On LAN function, you must have an Ethernet card with chipset that

supports this feature, and connect a cable from LAN card to motherboard WO

connector. The system identification information (probably IP address) is stored on

network card and because there is a lot of traffic on the Ethernet, you need to install

network management software, such as ADM, for the checking of how to wake up the

system.

Non- Maskable Interrupt used for event handling. When event is occurred, system will

receive an NMI and execute a unique task. To disable this function, please short CN18

by jumper cap.

This motherboard supports four USB ports. Two of them are on back panel connector, the

other two are on the left-bottom area of this motherboard. With proper cable, you can

connect them to front panel.

If you want to use external case-mounted speaker instead of internal buzzer, the 4-pins

external speaker connector can let you connect with external case-mounted speaker.

If you encounter any trouble to boot you system, follow the

procedures accordingly to resolve the problem.

Part Number and Serial Number

The Part Number and Serial number are printed on bar code label. You can find this

bar code label on the outside packing, on ISA/CPU slot or on component side of PCB.

For example:

Make sure if the jumper settings for CPU and DRAMs are correct.

Clear CMOS.

Install the VGA card. Then connect your monitor and keyboard.

The problem was probably caused

by power supply or motherboard

failure. Please contact your reselle

or local distributor for repairing.

Perhaps your VGA card or monito

is defective.

Yes

It is very possible that your keyboard

is defective.

During system rebooting, press Del to enter BIOS Setup. Choose

“Load Setup Default".

The problem should be caused by the

IDE cables or HDD itself.

Re-install Windows 95, Windows 98 or Windows NT.

Yes

Turn off the power and unplug the AC power cable, then remove all

of the addon cards and cables, including VGA, IDE, FDD, COM1,

COM2 and Printer.

Turn on the power, and check if

the power supply and CPU fan

work properly.

Start

Check if there is display.

Press Ctrl, and Alt key at the

same time, hold them and then

press Del to see if the

stem reboots.

Turn off the system and

re-connect the IDE cable.

Check if the system can

reboot successfully.
