Hardware Setup
If your mainboard has already been installed in your computer you may still need
to refer to this chapter if you plan to upgrade your system's hardware.
Besuretodisconnectthepowercablefromthepowersourcebeforeperforming
any work on your mainboard, i. e. installing a CPU, memory module,
changing a jumper setting, etc. Not doing so may result in electrical shock!
2-1 Introduction to Jumpers
Jumpers are used to select between various operating modes. A jumper consists of
a row of gold colored pins that protrude from the surface of the mainboard. It is
important not to confuse jumpers with connectors or headers.
Puttingjumpercapsonanythingthatisnotajumpermayresultindamaging
your mainboard. Please refer to Section 1-3, Mainboard Layout, for the
location of jumpers on your mainboard.
As indicated in Figure 2-1 below, a cap is used to cover the pins of a jumper, resulting
in shorting those pins that it covers. If the cap is removed from the top of the pins,
the jumper is left "open." The number 1 shown both in the diagram below and in
all multiple pin jumper and header diagrams in this manual indicates the pin
designated with the number 1. The numbering of the remaining pins follows in
sequence.

2-2 Installing a CPU in a Socket 370
The Intel Socket 370, designed for the Celeron and Coppermine processors, has been
incorporated as a standard mainboard specification. To insert your CPU into Socket
370 please do the following:
1. Locate a small dot marked on the top surface of the CPU close to one if it's
corners. The same corner will also be cut off, leaving a noticeable notch in
the CPU's corner. These markings indicate Pin 1 of the CPU.
2. Pull up the lever of Socket 370 so that it is perpendicular with the surface of
the mainboard. Gently insert the CPU with Pin 1 at the same corner of Socket
370 that contains the end of the lever. Allow the weight of the CPU to push
itself into place. Do not apply extra pressure as doing so may result in damaging
your CPU. Snap the lever back into place.
Installing a heat sink with cooling fan is necessary for proper heat dissipation
from your CPU. Failing to install these items may result in overheating and
possible burn-out of your CPU.
2-3 SettingYour CPU's Parameters
This board support plug and play CPU configuration, if you install a CPU on this
mainboard, the board will automatically detect and set CPU parameters. It is no longer
necessary to make many jumper settings as on conventional mainboards.
1. After installing all your hardware into your PC system, turn on your system's
power. Enter the CMOS Setup Utility by pressing the Delete key when your
BIOS identification screen appears.
2. Move the cursor to Frequency/Voltage Control Setup menu and press Enter. Find
the CPU bus frequency at the left hand side of the BIOS screen. Commands for
operating the cursor in BIOS are found at the Bottom right of the BIOS screen.
3. Set the CPU bus frequency according to your processor's specifications.
4. Press Esc to return to the CMOS Setup Utility, press F10 to Save and Exit Setup
and choose 'Y' to confirm. The system will automatically reboot and during startup
you will see the correct CPU type shown on the screen.
You do not need to make voltage settings because SeePU automatically
sets your CPU voltage.

Overclocking
Operating a CPU at a higher frequency than it's specification allows is called
overclocking. If the CPU frequency is set at a higher frequency than it's specification
allows, it may or may not run at that frequency, depending on the quality of your
CPU and the extent to which the frequency has been overset. The mainboard
manufacturer highly discourages overclocking as it may result in data loss, CPU
burnout, system failure, etc.
Many Intel processors are frequency locked processors and are not able to perform
overclocking. Regardlessof whethertheprocessoris afrequencylocked,overclocking
may cause some processors to hang when turning on the system. When the processor
hangs, the screen remains blank and the system does not boot. To solve this problem,
do the following.
1. Turn off the computer and then press and hold the Home key on your keyboard
2. Turn on your computer, wait for five seconds and then release the Home key.
3. Enter BIOS and reconfigure your CPU parameters as described in this section.

2-4 Connector and Jumper Settings
Connectors are used to link the system board with other parts of the system, including
the power supply, the keyboard, and the various controllers on the front panel of
the system case.
Thepower supplyconnector is the lastconnection tobe madewhileinstalling
amainboard. Before connecting thepower supply,please makesure itis not
connectedto thepower source.
ATX Power Supply Connector (CN12)
The power cord leading from the system's power
supply to the external power source must be the
very last part connected when assembling a system.
Tosupportthisfunction,aswitchingpower
supply with a minimum of 750mA 5VSB
is required.
The ATX power supply provides a single 20-pin
connector interface which incorporates standard +/
-5V, +/-12V, optional 3.3V and Soft-power signals.
The Soft-power signal, a 5V trickle supply is
continuously supplied when AC power is
available. When the system is in the Soft-Off
mode, this trickle supply maintains the system in
it's minimum power state.
Power-On By Modem
While in Soft-off state, if an external modem ring-up signal occurs, the system wakes
up and can be remotely accessed. You may enable this function in BIOS's Power
Management Setup menu.
Poly-fuse Over Current Protection
The poly-fuse protects the system from dangerous voltages the system might be
exposed to via the keyboard or USB connectors. In case of such exposure, the poly-
fuse will immediately be disconnected from the circuit, just like a normal fuse. After
being disconnected for a certain period of time, the poly-fuse will return to its normal
state, after which the keyboard or USB can function properly again. Unlike
conventional fuses, the poly-fuse does not have to be replaced, relieving the user
wasted time and inconvenience.

A.Over-ridePowerButtonConnector
The power button on the ATX chassis can be used
as a normal power switch as well as a device to
activate Advanced Power Management Suspend
mode. This mode is used for saving electricity
when the computer is not in use for long periods of
time. The Soft-OFF by PWR-BTTN function in
BIOS'sPowerManagementSetupmenumustbeset
to "Delay 4 Sec." to activate this function.
When the Soft-OFF by PWR-BTTN function is
enabled, pushing the power button rapidly will
switch thesystemtoSuspendmode. Anyoccurrence
of external activities such as pressing a key on the
keyboard or moving the mouse will bring the
system back to Full-On. Pushing the button while
in Full-On mode for more than 4 seconds will
switch the system completely off. See Over-ride
Power Button Operation diagram.
B.Power Indicator LED Connector
The power indicator LED shows the system's
power status. It is important to pay attention to
the correct cables and pin orientation (i.e., not to
reverse the order of these two connectors.)
Software Power-Off Control
This mainboard can be powered down using the Windows 95/98 Software Power-Off
function. To power down your computer, click the START button on the Windows
95/98 task bar. Select "Shut Down The Computer" and the system turns off. The
message "It is now safe to turn off your computer" will not be shown when using this
function.

C. Green Switch/Green LED Connector
Some ATX cases provide a Green switch which
is used to put the system in Suspend mode. In
Suspend mode, the power supply to the system
is reduced to a trickle, the CPU clock is stopped,
and the CPU core is in it's minimum power state.
The system is woken up whenever the keyboard
or mouse is touched. The system resumes in
different ways as defined by Power Management
Setup screen in BIOS.
D.SystemResetSwitchConnector
This connector should be connected to the reset
switch on the front panel of the system case. The
reset switch allows you to restart the system
without turning the power off.

F.IDEActivityLED Connector
The IDE activity LED lights up whenever the
system reads/writes to the IDE devices.
G.TurboLEDConnector
This mainboard does not have a Turbo/De-turbo

Blinking LED in Suspend Mode
While in Suspend mode, the LED light on the front panel of your computer will
flash. Suspend mode is entered by pressing the Override Power Button, pushing
the Green button on your ATX case, or enabling the Power Management and Suspend
