Hardware Setup
Chapter 2
If your motherboard 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.
This motherboard is electrostatic sensitive. Do not touch without
wearing proper safety gadget and make sure to disconnect the power
cable from the power source before performing any work on your
motherboard. Not doing so may result in electrical shock!
2-1 Installing a CPU Processor for Socket 478
The Intel® Socket 478, designed for the Pentium 4 processor, has been incorporated as
a standard motherboard specification. To insert your CPU into Socket 478 please
follow the steps bellow:
1. Locate the 478-pin CPU socket on the motherboard.
2. Unlock the socket by pressing the leaver sideways, and then open it up to a 90-degree
angle.
3. Locate a Gold Mark on the top surface of the CPU, which is close to one of the CPU
corners. The same corner will also be cut off, leaving a noticeable notch in the CPU's
corner. These markings indicate Pin 1 on the CPU.
4. Gently insert the CPU with Gold Mark/Pin 1 at the same corner of Socket 478, which
is located close to 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.
5. When the CPU is correctly inserted, close the leaver with your finger on to of the
CPU to make sure the CPU is properly embedded into the socket.
6. Insert an appropriate heat sink and fan for proper Heat dispatch.
Installing a standard Intel® specified 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.
2-2 Setting Your CPU's Performance
Frequency Configuration:
This motherboard uses a new user-friendly technology that enables the user to setup a
main board's CPU parameters through an easy to use BIOS setup procedure. It is no
longer necessary to make many jumper settings as on conventional motherboard.
After installing all your hardware into your PC system, you can manually configure
your CPU clock ratio and CPU clock according to your processor's specifications. By
turning on your system's power. Enable the CMOS Setup Utility by pressing the delete
key when your BIOS identification screen appears, then go to the Frequency/ Voltage
control option and select your CPU clock ration and CPU clock speed (please refer to
Chapter3 for more details).
You do not need to make voltage settings because this board will automatically
set your CPU voltage.
2-3 Main Memory Configuration
The SDRAM memory system consists two banks and can support the memory size up
to 1 GB per DIMM. If you only use one bank, it does not matter which one you use
and if you use two or more banks, it does not matter which bank you install first.

DIMM type: 3.3V, 64/72-bit 168 pin SDRAM.
Module size: Single/double-sided 32/64/128/256/512Mbytes or 1GBytes.
Parity: Either parity or non-parity.
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.
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. 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 its minimum power
state.
The ATX 12V power supply has a new +12V (4-pin) and +5V/3.3V (6-pin) auxiliary
power connector. To enable the delivery of more +12 VDC and +5/3.3V VDC current
to the motherboard.
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. (See section 3. 5)
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 Mode
options in BIOS's Power Management menu. (See section 3.5)
The poly-fuse protects the system from dangerous voltages that the system might be
exposed to via the keyboard or USB connector. 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.
Then the keyboard or USB connector can function properly again. Unlike conventional
fuses, the poly-fuse does not have to be replaced, relieving the user wasted time and
inconvenience.

DRAM Specifications
The power supply connector is the last connection to be made while
installing a motherboard. Before connecting the power supply, please
make sure it is not connected to the power source.

Blinking LED in Suspend Mode
Poly-fuse Over Current Protection
CN1A (Front Panel Connector)
1. PWR-SW (Over-ride Power Button Connector)
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's Power Management Setup menu must
be set to [Delay 4 Sec.] to activate this function.
