Introduction
Hardware Monitoring System Utility
The mainboard comes with the Hardware Monitoring System utility contained
on the CD. It is capable of monitoring the system’s hardware conditions such
as the temperature of the processor, voltage, and the speed of both the CPU
and chassis fans. You are allowed to manually set a range to the items being
monitored. If the values are over or under the set range a warning message
will automatically pop up. We recommend that you use the Default Settings,
which are the ideal settings that will maintain the system in a good working
condition. To install this utility, please insert the CD into the CD-ROM drive.
The auto run screen (Driver Utility) will automatically appear. Click the Hard-
ware Monitoring button, choose the chipset, model number and the OS that is
installed. Please refer to the CD “Readme” file for further installation instruc-
tions.
Note: Only use this utility in Windows operating systems.
The mainboard is capable of monitoring the following health conditions of your
system:
1. Processor temperature. It has an overheat alarm.
2. VCORE/3.3V/5V/12V/-12V voltages and failure alarm.
3. Processor and chassis fan speeds. It has a failure alarm for these fans.
4. Read back capability that displays temperature, voltage and fan speed.
%"!&'( !
Dual Function Power Button
Depending on the setting in the Soft-Off By Power-Button field of the Power
Management Setup, this switch allows the system to enter the Soft-Off or
Suspend mode.
RTC Timer to Power-on the System
The RTC installed on the system board allows your system to automatically
power-on at a set date and time.
Wake-On-LAN Ready

2.4.2. Memory Modules
The mainboard has three 184-pin DDR DIMM slots which are located on the
right-hand side of the board. The maximum supported memory is 3 GB. To
install the DIMMs into these slots, make sure the white lever at each side of
the slot has been pulled down to an angle of approximately 45. Make sure
that the DIMM is in the correct orientation. Place the DIMM on the slot and
push down firmly.The white levers will come back up and lock the module in
place.
Hardware Installation
2.4.1. Installation of the CPU
To install your processor, please complete the following set of instructions:
1. Locate a small dot marked on the top of the CPU. This mark indicates Pin
of the CPU.
2. Locate Pin 1 for the Socket on the mainboard.
3. There is a lever on the side of the socket. First push this lever sideways
and then lift it to a 90-degree angle.
4. Insert the CPU into the Socket. Please make sure that Pin 1 for the CPU is
inserted into Pin 1 of the Socket.
5. When the CPU is installed correctly push the lever back into place.
6. Install a proper heat sink with cooling fan for proper heat dissipation.
Failing to install a heat sink with cooling fan may cause overheating which
will burnout your CPU and damage your mainboard.
IMPORTANT: CPU COOLING FAN
Please ensure that you have an approved heat sink with cooling fan.
Without a proper heat sink with cooling fan you will damage both the
mainboard and the CPU.
%/-&#!"!
Important: The DIMM’s can only be fitted into the slots in one orienta-
tion. Make sure that the DIMM’s are in the correct orientation and the
pins are correctly aligned before you insert them.

2.5.6. CD-IN/AUX-IN Connector
Connector: CN21 (CD-IN)/CN45 (AUX-IN)
Type: 4 pin un-housed
The mainboard has one CD-IN connector and one AUX-IN connector. The CD-
IN connector is used to connect the CD ROM audio out and allows the system
to receive audio input from the CD ROM. The AUX-IN connector allows the
system to receive signals from other audio devices like a radio or tape.
2.5.7. WOL (Wake-On-LAN) Connector
Connector: CN16 (WOL)
Type: 3 pin
The mainboard has a WOL (Wake-On-LAN) connector. This connector must be
connected to a LAN card that has Wake-On-LAN (WOL) output. This connector
powers up the system when a wakeup packet or signal is received through the
LAN card.
In order to use the WOL LAN card to trigger the power on the PC system, the
switching power supply must have the ability to provide a driving current of at
least 720 mA and be connected to a “5V standby” voltage.

&> +
The front audio connector is an innovative development. This connector is de-
signed to be used with a Front-Utility Panel. The utility panel was developed so
that a user is able to bring the speaker out, microphone in connectors to the
front of their PC. This makes things like plugging in speakers and earphones
much less troublesome.
2.5.8. USB3, USB4, USB5, USB6 Connectors
Connector: CN30 (USB 3)/CN31 (USB 4)/CN32 (USB5)/CN38 (USB6)
Type: 5 pin
You already have two USB2.0 ports available, USB1 and 2 (see external con-
nectors). The internal USB connectors allow you to add on an optional kit to
expand the total number of USB ports available. The mainboard has four inter-
nal USB2.0 connectors (CN30/CN31/CN32/CN38). This enables you to use an
extra four USB devices. Cable for these additional connectors needs to be pur-
chased separately.
Note: The PIN assignment of the internal USB 2.0 connectors (CN30, CN31,
CN32 and CN38) are follow the specifications of Intel standard.
