Hardware Setup
This chapter provides you with the information about
hardware setup procedures. While doing the installation,
be careful in holding the components and follow the
installation procedures. For some components, if you
install in the wrong orientation, the components will not
work properly.
Use a grounded wrist strap before handling computer
components. Static electricity may damage the
components.

Hardware Setup
CPU (Central Processing Unit)
This mainboard supports Intel® Pentium 4 (Quad-Core Kentsfield/Yorkfield & DualCore Conroe/Wolfdale/Celeron D) processors in LGA775 package. When you install
the CPU, make sure that you install the cooler to prevent overheating. If you
do not have the CPU cooler, consult your dealer before turning on the computer.
Important
Overheating
Overheating will seriously damage the CPU and system. Always make sure
the cooling fan can work properly to protect the CPU from overheating. Make
sure that you apply an even layer of thermal paste (or thermal tape) between
the CPU and the heatsink to enhance heat dissipation.
Replaceing the CPU
While replacing the CPU, always turn off the power supply or unplug the
power supply’s power cord from the grounded outlet first to ensure the safety
of CPU.

CPU & Cooler Installation
When you are installing the CPU, make sure the CPU has a cooler attached on
the top to prevent overheating. Meanwhile, do not forget to apply some thermal
paste on CPU before installing the heat sink/cooler fan for better heat dispersion.
Follow the steps below to install the CPU & cooler correctly. Wrong installation will
cause the damage of your CPU & mainboard.
1.The CPU socket has a plastic cap
on it to protect the contact from
damage. Before you install the CPU,
always cover it to protect the socket
pin.
3.The pins of socket reveal.
2.Remove the cap from lever hinge
side (as the arrow shows).
4.Open the load lever.
Important
1.Confirm if your CPU cooler is firmly installed before turning on your system.
2. Do not touch the CPU socket pins to avoid damaging.
3. The availability of the CPU land side cover depends on your CPU packing.
2-4
Hardware Setup
5.Lift the load lever up and open the
load plate.
7.Visually inspect if the CPU is
seated well into the socket. If not,
take out the CPU with pure vertical
motion and reinstall.
6.After confirming the CPU direction
for correct mating, put down the
CPU in the socket housing frame.
Be sure to grasp on the edge of
the CPU base. Note that the alignment keys are matched.

8.Cover the load plate onto the
package.

9.Press down the load lever lightly
onto the load plate, and then secure the lever with the hook under
retention tab.
11.Press the four hooks down to fasten
the cooler. Then rotate the locking
switch (refer to the correct direction
marked on it) to lock the hooks.
10. Align the holes on the mainboard
with the heatsink. Push down the
cooler until its four clips get
wedged into the holes of the
mainboard.
12.Turn over the mainboard to confirm that the clip-ends are correctly
inserted.

Important
1. Read the CPU status in BIOS (Chapter 3).
2. Whenever CPU is not installed, always protect your CPU socket pin with the
plastic cap covered (shown in Figure 1) to avoid damaging.
3. Mainboard photos shown in this section are for demonstration of the CPU/
cooler installation only. The appearance of your mainboard may vary depending on the model you purchase.

Installing Memory Modules
1. Locate the DIMM slots on the mainboard. Flip open the retaining clip at each side
of the DIMM slot.
2. Align the notch on the DIMM with the key on the slot. Insert the DIMM vertically into
the DIMM slot. Then push it in until the golden finger on the DIMM is deeply inserted
in the DIMM slot. The retaining clip at each side of the DIMM slot will automatically
close if the DIMM is properly seated.
Important
You can barely see the golden finger if the DIMM is properly inserted in the
DIMM slot.
3. Manually check if the DIMM has been locked in place by the retaining clips at the
sides.

Power Supply
24-Pin System Power Connector: JPWR1
This connector allows you to connect a 24-pin power supply. To
connect the 24-pin power supply, make sure the power supply
connector is inserted in the proper orientation and the pins are
aligned. Then push down the power supply firmly into the connector.
You may use the 20-pin power supply as well. If you’d like to use the
20-pin power supply, please align your power supply connector
with pin 1 & pin 13. There is also a foolproof design on pin 11, 12, 23
& 24 to avoid wrong installation.

BIOS Recovery Jumper: J_BOOT1
Users can short connect pin#2-3 to recover the system BIOS with a Recovery
Floppy. When the system is done with the job, the buzzer will beep to remind the user
to set the jumper to its normal state (pin#1-2 short connected).

Clear CMOS Jumper: J_CMOS1
There is a CMOS RAM onboard that has a power supply from an external battery to
keep the data of system configuration. With the CMOS RAM, the system can automatically boot OS every time it is turned on. If you want to clear the system configuration,
set the jumper to clear data.

* The CF1 slot and the IDE1 connector shares and uses the same channel. CF1
and IDE1 can support up to 2 IDE devices without CF device or 1 IDE device
with 1 CF device.
* If you install two IDE devices, you must configure the second drive to Slave
mode by setting its jumper. Refer to the hard disk documentation supplied by
hard disk vendors for jumper setting instructions.
* If you install one IDE device with ATA133 IDE cable and one CF device, you
must configure the CF drive to Master mode by setting jumper JCF_SEL1.
CF only supports Master mode by using ATA133 IDE cable. CF only supports
Slave mode by using ATA33 IDE cable.

BIOS Setup
This chapter provides information on the BIOS Setup
program and allows you to configure the system for
optimum use.
You may need to run the Setup program when:
² An error message appears on the screen during the
system booting up, and requests you to run SETUP.
² You want to change the default settings for cus-
tomized features.

1.The items under each BIOS category described in this chapter are under
continuous update for better system performance. Therefore, the description may be slightly different from the latest BIOS and should be held for
reference only.
2.Upon boot-up, the 1st line appearing after the memory count is the BIOS
version. It is usually in the format:
3-2
A91A2IMS V1.x 051110 where:
1st digit refers to BIOS maker as A = AMI, W = AWARD, and P =
PHOENIX.
2nd - 5th digit refers to the model number.
6th digit refers to the chipset as I = Intel, N = nVidia, and V = VIA.
7th - 8th digit refers to the customer as MS = all standard customers.
V1.x refers to the BIOS version.
051110 refers to the date this BIOS was released.

another to ensure that the receiving device can handle all of the incoming data.
This is particularly important where the sending device is capable of sending
data much faster than the receiving device can receive it.
Redirection After BIOS POST
This setting determines whether or not to keep terminals’ console redirection
running after the BIOS POST has booted.

Quick Boot
Enabling this setting will cause the BIOS power-on self test routine to skip some
of its tests during bootup for faster system boot.
Quiet Boot
This BIOS feature determines if the BIOS should hide the normal POST messages with the motherboard or system manufacturer's full-screen logo.
When it is enabled, the BIOS will display the full-screen logo during the boot-up
sequence, hiding normal POST messages.
When it is disabled, the BIOS will display the normal POST messages, instead of
the full-screen logo.
Please note that enabling this BIOS feature often adds 2-3 seconds of delay to
the booting sequence. This delay ensures that the logo is displayed for a
sufficient amount of time. Therefore, it is recommended that you disable this
BIOS feature for a faster boot-up time.
Bootup Num-Lock
This setting is to set the Num Lock status when the system is powered on.
Setting to [On] will turn on the Num Lock key when the system is powered on.
Setting to [Off] will allow users to use the arrow keys on the numeric keypad.

Set this option to [Disabled] to prevent the message as follows:
It will prevent the message from appearing on the first BIOS screen when the
computer boots. Set it to [Enabled] when you want to run the BIOS Setup Utility.
