This jumper is used to activate either the EEPROM chipset on CNR card or the onboard

EEPROM chipset. With onboard LAN equipped on this motherboard, you may short pins

1-2 to enable the onboard EEPROM for running onboard LAN. However, if you were to

use CNR card to run LAN, you may short pins 2-3 to disable the onboard EEPROM

chipset.

5. Setting CPU Voltage & Frequency

Setting CPU Core Voltage

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

detected and the range is from 1.05V to 1.825V.

Setting CPU Frequency

CPU frequency can be set through the BIOS setup.

BIOS Setup > Frequency / Voltage Control > CPU Speed Setting

Core Frequency = CPU FSB Clock * CPU Ratio

CPU Ratio 3x, 3.5x, 4x, 4.5x, 5x, 5.5x, 6x, 6.5x, 7x, 7.5x, 8x, 8.5x, 9x, 9.5x, 10x, 10.5x, 11x,

Warning: Intel®815E B-Step /

815EP B-Step chipset supports

maximum 133MHz FSB and

66MHz AGP clock, higher clock

setting may cause serious

system damage.

Warning: To avoid possible CPU damage caused by overheating, an automatic

shutdown of system had been especially designed on this motherboard. System

would be automatically power off when this motherboard with implementation of

THERMTRIP circuit detected a CPU temperature above 135 degree for 4 seconds.

9. Connecting Front Panel Cable

This motherboard provides four USB connectors to connect USB devices, such as mouse,

keyboard, modem, printer, etc. There are two connectors on the PC99 back panel. You

can use proper cable to connect the other USB connector to the back panel or front panel

of chassis.

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

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

damage.

ttach the power LED, Keylock, speaker, and reset switch connectors to the corresponding

pins. If you enable “Suspend Mode” item in BIOS Setup, the ACPI & Power LED will keep

flashing while the system is in suspend mode.

Locate the power switch cable from your ATX housing. It is 2-pin female connector from the

housin

Intel 815E B-Step/815EP B-Step (Solano Series) includes a fast Ethernet controller on

chip. On the strength of Intel 82562ET/EM PHY on board, which is a highly-integrated

Platform LAN Connect device, it provides 10/100M bps Ethernet for office and home use,

the Ethernet RJ45 connector is located on top of USB connectors. The green LED

indicate the link mode, it lights when linking to network; and the yellow LED indicates the

transfer mode, it lights when transferring data in 100Mbps mode.

The IrDA connector can be configured to support wireless infrared module, with this

module and application software such as Laplink or Windows 95 Direct Cable Connection,

the user can transfer files to or from laptops, notebooks, PDA devices and printers. This

connector supports HPSIR (115.2Kbps, 2 meters) and ASK-IR (56Kbps).

Install the infrared module onto the IrDA connector and enable the infrared function from

BIOS Setup, UART mode select, make sure to have the correct orientation when you plug

in the IrDA connector.

The CD-IN connector is used to connect CD Audio cable from CDROM or DVD drive to

onboard sound. The MODEM-CN connector is used to connect Mono In/ Mic Out cable from

internal modem card to onboard sound circuit.

The South Bridge in Intel i815E B-Step/i815EP B-Step (Solano Series) integrates a total

communication solution including 10/100Mb Fast Ethernet for Office requirement. You can install

LAN Driver under Windows95/98/ME, WindowsNT & Windows2000 by following steps.

Manually Adding an Adapter in Windows 95 / 98 / ME / NT4 / 2000

=====================================

LOCATION OF DRIVER: \Driver\Lan\E100BNT5.SYS (NDIS 5.0)

LOCATION OF SETUP FILE: \Driver\Lan\NET82557.INF

1. From the Control Panel, double-click the “Add Hardware” icon.

2. Double-click Other Devices or NetworkAdapters in the list area.

3. Double-click a PCI Ethernet Controller.

4. Click the Driver tab, then click Update Driver.

5. Click Next at the Update Device Driver Wizard.

6. Select "Display a list of all the drivers..." and click Next.

7. Insert the AOpen Bonus CD and click Have Disk.

8. Enter the appropriate drive for your disk media

(for example: D:\) ,and click OK.

9. Click OK at the Select Device dialog box.

10. The Update Wizard displays the message that it has found

the driver. Click Next.

11. Click Finish and restart your computer when prompted.

Note: If the Ne

Hardware Found dialo

box does not appear a

startup and you canno

connect to the network,

check the Device

Manager list to see if the

new adapter is present.

If it is not,

lease instal

the LAN driver manually.

11. Front Audio Connector

If the housing has been designed with an audio port on the front panel, you’ll be able to

connect onboard audio to front panel through this connector. By the way, please remove

5-6 and 9-10 jumper caps from the Front Audio Connector before connecting the cable.

Please do not remove these 5-6 and 9-10 yellow jumper caps if there’s no audio port on

the front panel.

fter you finish the setting of jumpers and connect correct cables. Power on

and enter the BIOS Setup, press <Del> during POST (Power On Self Test).

Choose "Load Setup Defaults" for recommended optimal performance.

14. Power-on and Load BIOS Setup

15. AOpen Bonus Pack CD 17. BIOS Upgrade

Open Easy Flash is more use

-friendly than traditional flash method. The BIOS binary

file and flash routine are combined together and you simply run a single file to complete

the flash process.

1. Download new BIOS upgrade zipped file from AOpen's web site. For example,

MX3SPU102.ZIP.

2. Run shareware PKUNZIP (http://www.pkware.com) which supports

miscellaneous operation systems to extract the binary BIOS file and the flash

utility. Or Winzip (http://www.winzip.com/) in Windows environment.

3. Save the unzipped file into a bootable floppy disk.

For example, MX3SPU102.BIN & MX3SPU102.EXE

4. Reboot the system to DOS mode without loading any memory handler (such as

EMM386) or device driver. It needs around 520K free memory space.

5. Execute A:> MX3SPU102 and the program will do the rest of it.

DO NOT turn off the power during FLASH PROCESS until you are asked to!!

6. Reboot system and press <Del> to enter BIOS Setup, Choose "Load Setup

Defaults", then “Save & Exit Setup” and finish the BIOS upgrade.

Warning: The upgrade of new BIOS will permanently replace your original BIOS

content after flashing. The original BIOS setting and Win95/Win98 PnP information

will be refreshed and

Warning: Please avoid of using "Load

Turbo Defaults", unless you are sure

our system components (CPU, DRAM,

HDD, etc.) are good enough for turbo

settin

This motherboard comes with an AD 1885 AC97 CODEC, you can find the audio drive

from the Bonus Pack CD disc auto-run menu.

Note: Before you start installing

the onboard sound chip driver,

lease make sure your system

had been installed Microsoft

DirectX 5 or later version. You

can find DirectX setup program

in AOpen Bonus Pack CD

auto-run menu.

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:

Model name and BIOS version

MX3SPU R1.00 Feb. 01. 2001 AOpen Inc.

ward Plug and Play BIOS Extension v1.0A

Model name and BIOS version can be found on upper left corner of first boot screen

(POST screen). For example:

MX3SPU is model name of motherboard; R1.00 is BIOS version

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.
