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)  
When you are installing the CPU, make sure to 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 ATX power supply or unplug the  
power supplys power cord from the grounded outlet first to ensure the safety  
of CPU.  
Overclocking  
This mainboard is designed to support overclocking. However, please make  
sure your components are able to tolerate such abnormal setting, while  
doing overclocking. Any attempt to operate beyond product specifications is  
not recommended. We do not guarantee the damages or risks caused  
by inadequate operation or beyond product specifications.

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 fromdamage.  
Before you install the CPU, always  
cover it to protect the socket pin.  
2. Remove the cap from lever hinge  
side (as the arrow shows).  
3. The pins of socket reveal.  
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.

Hardware Setup  
5. Lift the load lever up and open the  
load plate.  
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 align-  
ment keys are matched.

7. Visually inspect if the CPU is  
seated well into the socket. If not,  
take out the CPU with pure vertical  
motion and reinstall.  
8. Cover the load plate onto the  
package.

9. Press down the load lever lightly  
onto the load plate, and then se-  
cure the lever with the hook under  
retention tab.  
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.  
11. Press the four hooks down to fas-  
ten the cooler. Then rotate the lock-  
ing switch (refer to the correct di-  
rection marked on it) to lock the  
hooks.  
12. Turn over the mainboard to con-  
firm that the clip-ends are cor-  
rectly 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 depend-  
ing on the model you purchase.

Installing Memory Modules  
1. The memory module has only one notch on the center and will only fit in the right  
orientation.  
2. Insert the memory module vertically into the DIMM slot. Then push it in until the  
golden finger on the memory module is deeply inserted in the DIMM slot.  
Important  
You can barely see the golden finger if the memory module is properly inserted  
in the DIMM slot.  
3. The plastic clip at each side of the DIMM slot will automatically close.

Important  
- DDR2 memory modules are not interchangeable with DDR and the DDR2  
standard is not backwards compatible. You should always install DDR2  
memory modules in the DDR2 DIMM slots.  
- In Dual-Channel mode, make sure that you install memory modules of the  
same type and density in different channel DIMM slots.  
- To enable successful system boot-up, always insert the memory modules  
into the DIMM_A1 first.

Entering Setup  
Power on the computer and the system will start POST (Power On Self Test) process.  
When the message below appears on the screen, press <Del> key to enter Setup.  
Press Del to enter SETUP  
If the message disappears before you respond and you still wish to enter Setup,  
restart the system by turning it OFF and On or pressing the RESET button. You may  
also restart the system by simultaneously pressing <Ctrl>, <Alt>, and <Delete> keys.  
Important  
1. The items under each BIOS category described in this chapter are under  
continuous update for better system performance. Therefore, the descrip-  
tion 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:  
A9820IMS V1.0 031508 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.  
V1.0 refers to the BIOS version.  
031508 refers to the date this BIOS was released.

Execute-Disable Bit Capability  
Intel's Execute Disable Bit functionality can prevent certain classes of  
malicious "buffer overflow" attacks when combined with a supporting  
operating system. This functionality allows the processor to classify areas in  
memory by where application code can execute and where it cannot. When  
a malicious worm attempts to insert code in the buffer, the processor  
disables code execution, preventing damage or worm propagation.

The S3 sleep mode is a lower power state where the  
information of system configuration and open appli-  
cations/files is saved to main memory that remains  
powered while most other hardware components turn  
off to save energy. The information stored in memory  
will be used to restore the system when a wake up”

block code to memory in right segments. Copies BIOS from ROM to RAM  
for faster access. Performs main BIOS checksum and updates recovery  
status accordingly.
