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

connectors.

1. Pull up the CPU socket lever 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 lever and finish

CPU installation.

Note: If you do not match the CPU

socket Pin 1 and CPU cut edge

well, it may damage the CPU.

Setting CPU Core Voltage

This motherboard supports CPU VID function. The CPU core voltage will be automatically

detected and the range is from 1.10V to 1.85V. It is not necessary to set CPU Core

Voltage.

Setting CPU Frequency

The CPU Frequency will be automatically detected. It is not necessary to set CPU

Frequency.

Core Frequency = CPU FSB Clock * CPU Ratio

Connect 34-pin floppy cable and 40-pin, 80-wire IDE cable to floppy connector FDC and

IDE connector. Be careful of the pin1 orientation. Wrong orientation may cause system

damage.

You can clear CMOS to restore system default setting. To

clear the CMOS, follow the procedure below.

1. Turn off the system and unplug the AC power.

2. Remove ATX power cable from connector PWR2.

3. Locate JP14 and short pins 2-3 for a few seconds.

4. Return JP14 to its normal setting by shorting pin 1 & pin 2.

5. Connect ATX power cable back to connector PWR2.

Tip: When should I Clear CMOS?

1. Boot fail because of

overclocking…

2. Forget password…

8. Connecting Front Panel Connector

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

corresponding pins.

9. Connecting 68pin Ultra320 SCSI Cable

6. Install DIMM Modules

The AX4S Plus-U provides one 68-pin Ultra320 SCSI connectors for 16-bit or 16-bit

differential SCSI devices. The Adaptec AIC-7901X controller provides 160MB/sec

maximum data throughput. (AX4S Plus-U only)

This motherboard has four 184-pin DIMM sockets that allow you to install PC200/266

Registered memory up to 4.0GB.

This motherboard comes with a 20-pin and 4-pin ATX power connector. Make sure you

plug in the right direction. We strongly recommend you to connect the 4-pin 12V ATX

connector before connecting the 20-pin ATX power connector

12. Support 1Gbps LAN onboard

13. JP15 Boot Block Jumper

10. PC99 Color Coded Back Panel

11. ZCR (Zero Channel RAID) Function

When the PC tries to boot and finds the BIOS code corrupted, the boot block will

try to recover the BIOS code. You may have to change JP15 setting to enable this

capability. The boot block will load the BIOS code and then when you next reboot,

the regular BIOS code should be in place and the problem resolved.

The onboard I/O devices are PS/2 Keyboard, PS/2 Mouse, COM1, VGA, Printer and

USB1.1. The view angle of drawing shown here is from the back panel of the housing.

JP15 Boot Block Jumper

PS/2 Keyboard: For standard keyboard, which is using a PS/2 plug.

PS/2 Mouse: For PC-Mouse, which is using a PS/2 plug.

USB Port: Available for connecting USB devices.

Parallel Port: To connect with SPP/ECP/EPP printer.

COM1/COM2: To connect with pointing devices, modem or others serial devices.

A ZCR card is a PCI card that allows a RAID card to use the onboard SCSI chip, thus

lowering cost of RAID solution.

A "Zero-channel" RAID adapter is a PCI RAID

controller that doesn't have any SCSI channels on board. Instead, it is designed to

use the on-board SCSI channels of the motherboard to implement a cost-effective

Hardware RAID solution. Please be informed that only the first PCI slot supports

ZCR function. (AX4S Plus-U only)

The Intel 82540EM integrates Intel’s fourth-generation Gigabit MAC design with fully

integrated, physical-layer circuitry to provide a standard IEEE 802.3 Ethernet interface for

1000BASE-T and 100BASE-TX applications. The left green LED indicates the link mode,

it lights when linking to network and blinking when transferring data. The right green LED

indicates the transfer mode, and it lights when data is transferring in 1Gbps/100Mbps

mode.

and integrators. They should know your system configuration very well and

should be able to solve your problem efficiently and provide important

reference for you if next time you want to buy something else from them.

before contacting us. The part number, serial number and BIOS version

are also very helpful.

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 monitor 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 2000.

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.
