Everything you need to boot this
motherboard is included in this Easy
Installation Guide. For more
information, a complete Online User's
Manual can be found in the Bonus
Pack CD Disc. Thanks for the help of
saving our earth. Tip: When should I Clear CMOS?
1. Boot fail because of overclocking…
2. Forget password…
3. Troubleshootin
g
…
You can clear CMOS to restore system default setting.
To clear the CMOS, follow the procedure below.
1. Turn off the system and unplug theAC 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 pins 1-2.
5. Connect ATX power cable back to connector PWR2.

This jumper is used to enable or disable Keyboard/Mouse
Wake Up function. If you select Enable, you can decide the
wake up mode from BIOS Setup > Integrated Peripherals >
Power On Function. To implement this function, the power
supply 5V standby current must be greater than 800mA.
Note that only PS/2 mouse supports Wake on Mouse
function.

Warning: INTEL i815E/i815EP chipset supports
maximum 133MHz FSB and 66MHz AGP clock,
higher clock setting may cause serious system
damage.
Tip: If your system hangs or fails to boot
because of overclocking, simply use JP14 to
clear CMOS and restore to the default setting .

Installing CPU and Fan
Plug CPU to Socket370. Be careful of CPU orientation.
Plug in the fan cable to the 3-pin CPUFAN or FAN 1
connector.
Note: Some CPU fans do not
have sensor pin, so that cannot
support fan monitoring.
Auto-Detect CPU Core Voltage
This motherboard supports Celeron / Pentium III CPU VID function. The CPU
core voltage will be automatically detected and the range is from 1.3V to 3.5V.
Setting CPU Frequency
The CPU frequency selection is set by going into:
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup
Core Frequency = CPU FSB Clock * CPU Ratio
CPU CPU Core Frequency FSB Clock Ratio
Celeron 300A 300MHz 66MHz 4.5x

JP23/JP29 FSB/PCI Clock Ratio
This jumper is used to specify the relationship of PCI and
host clock. Generally speaking, we suggest you do not
change the default setting. But for overclocking, changing
these jumper settings becomes necessary. For example,
you must set JP29 to “5-6” and JP23 to “3-4” if you want to
overclock a 66MHz FSB clock CPU to 100MHz or higher.

Connecting IDE and Floppy Cable
Connect 34-pin floppy cable and 40-pin IDE cable to floppy connector FDC and IDE
connector IDE1, IDE2. Pin1 of cable is normally marked with red color. 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 Power Management > ACPI Function in
BIOS Setup, the ACPI & Power LED will keep
flashing while the system is in suspend mode.
Connecting Front Panel Cable
Locate the power switch cable from your AT
X
housing. It is 2-pin female connector from the
housing front panel. Plug this connector to the
soft-power switch connector marked SPWR.

Configuring System Memory
This motherboard has two 168-pin DIMM sockets that
allow you to install PC133 memory up to 512 MB. Only
SDRAM is supported.
Pin 1
Tip: The driving capability of new generation
chipset is limited due to the lack of a memory
buffer (to improve performance). This makes
DRAM chip count an important factor to take
into consideration when you install DIMMs.
Unfortunately, there is no way that the BIOS
can identify the correct chip count, you need
to calculate the chip count by yourself. The
simple rule is: By visual inspection, use
only DIMMs which are less than 18 chips.

Intel i815E/i815EP (Solano Series) includes a fast Ethernet controller on chip. On the
strength of Intel 82562EM, 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 indicates the link mode, it lights
when linking to net
w
ork and blinking when transferring data. The orange LED indicates
the transfer mode, it will light when transferring data in 100Mbps mode.
Note: This motherboard implements special
technology to support Wake On LAN. To take
advantage of this function, you will need to insert
an add
-

If the housing has been design 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
the jumper cap from the Front Audio Connector before you connect the cable. Do not
remove this yellow jumper cap if housing without an audio port on the front panel.

Installing Onboard Sound Driver
This motherboard comes with an AD 1885AC97 CODEC. You can find the audio
driver from the Bonus Pack CD disc autorun menu.
BIOS Upgrade
A
Open Easy Flash is more user 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.Get new BIOS upgrade program from AOpen's web site. For example,
MX3SP102.EXE. It is recommended to save it to a bootable DOS floppy diskette fo
r
error recovery.
2. Reboot the system to DOS mode without loading any memory handler (such as
EMM386) or device driver. It needs around 520K free memory space.
3. Execute A:> MX3SP102
DO NOT turn off the power during FLASH PROCESS!
4. Reboot system and press <Del> to enter BIOS setup, Choose "Load Setup Defaults",
then “Save & Exit Setup”. Done!
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 you probably need
to re-configure your system.
Power-on and Load BIOS Setup
A
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.
Del
Warning: Please avoid of using "Load Turbo
Defaults", unless you are sure your system
components (CPU, DRAM, HDD, etc.) are
good enough for turbo setting.
Installing LAN Driver
The South Bridge in Intel i815E/i815EP (Solano Series) integrates a total
communication solution including 10/100Mb Fast Ethernet for Office requirement. You
can install LAN Driver under Windows95/98, WindowsNT & Windows2000 by
following steps.
Manually Adding an Adapter in Windows 95 / 98
=====================================
LOCATION OF DRIVER: \Intel\Driver\Lan\E100BNT5.SYS (NDIS 5.0)
LOCATION OF SETUP FILE: \Intel\Driver\Lan\NET82557.INF
1. From the Control Panel, double-click the “Add Hardware” icon.
2. Double-click Other Devices or Network Adapters 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 theAOpen 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.
Note: If the New
Hardware Found
dialog box does not
appear at startup
and you cannot
connect to the
network, check the
Device Manager list
to see if the new
adapter is present. I
f
it is not, please
install the LAN
driver manually.

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.
