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 the CPU has a heat sink and a
cooling fan attached on the top to prevent overheating. If you do not have the
heat sink and cooling fan, contact your dealer to purchase and install them before
turning on the computer.
Important
1. Overheating will seriously damage the CPU and system. Always make
sure the cooling fan can work properly to protect the CPU from overheating.
2. Make sure that you apply an even layer of heat sink paste (or thermal tape)
between the CPU and the heatsink to enhance heat dissipation.
3. 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 Installation Procedures for Socket AM2
1.Please turn off the power and
unplug the power cord before
installing the CPU.
2.Pull the lever sideways away
from the socket. Make sure to
raise the lever up to a 90-degree angle.
3.Look for the gold arrow of the
CPU. The gold arrow should
point as shown in the picture.
The CPU can only fit in the correct orientation.
4.If the CPU is correctly installed,
the pins should be completely
embedded into the socket and
can not be seen. Please note
that any violation of the correct
installation procedures may
cause permanent damages to
your mainboard.
5. Press the CPU down firmly into
the socket and close the lever.
As the CPU is likely to move while
the lever is being closed, always close the lever with your
fingers pressing tightly on top of
the CPU to make sure the CPU is
properly and completely embedded into the socket.

Installing AMD Socket AM2 CPU Cooler Set
When you are installing the CPU, make sure the CPU has a heat sink and a
cooling fan attached on the top to prevent overheating. If you do not have the
heat sink and cooling fan, contact your dealer to purchase and install them before
turning on the computer.
Important
Mainboard photos shown in this section are for demonstration of the cooler
installation for Socket AM2 CPUs only. The appearance of your mainboard
may vary depending on the model you purchase.
1.Position the cooling set onto the retention mechanism. Hook one end
of the clip to hook first.
3.Fasten down the lever.
2. Then press down the other end of
the clip to fasten the cooling set on
the top of the retention mechanism.
Locate the Fix Lever and lift it up.

240-pin, 1.8V
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.
4. Follow the same procedures to install more DIMMs if necessary.

Clear NVRAM
The ESCD (Extended System Configuration Data) NVRAM (Non-volatile Random Access Memory) is where the BIOS stores resource information for both PNP and nonPNP devices in a bit string format. Whent the item is set to Yes, the system will reset
ESCD NVRAM right after the system is booted up and then set the setting of the item
back to No automatically.
Plug and Play O/S
When set to [Yes], BIOS will only initialize the PnP cards used for booting (VGA, IDE,
SCSI). The rest of the cards will be initialized by the PnP operating system like
Windows 98, 2000 or ME. When set to [No], BIOS will initialize all the PnP cards.
Select Yes if the operating system is Plug & Play.
PCI Latency Timer
This item controls how long each PCI device can hold the bus before another takes
over. When set to higher values, every PCI device can conduct transactions for a
longer time and thus improve the effective PCI bandwidth. For better PCI performance,
you should set the item to higher values.

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.
AddOn ROM Display Mode
This item is used to determine the display mode when an optional ROM is
initialized during POST. When set to [Force BIOS], the display mode used by AMI
BIOS is used. Select [Keep Current] if you want to use the display mode of
optional ROM.
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.
PS/2 Mouse Support
Select [Enabled] if you need to use a PS/2-interfaced mouse in the operating
system.
Boot Device Priority, Removable Drives
The items allow you to set the sequence of boot devices/removable drives. First
press <Enter> to enter the sub-menu. Then you may use the arrow keys ( ↑↓ ) to
select the desired device, then press <+>, <-> or <PageUp>, <PageDown> key to
move it up/down in the priority list.

Boot Sector Virus Protection
This function protects the BIOS from accidental corruption by unauthorized users or
computer viruses. When enabled, the BIOS’ data cannot be changed when attempting to update the BIOS with a Flash utility. To successfully update the BIOS, you’ll
need to disable this Flash BIOS Protection function.
You should enable this function at all times. The only time when you need to disable
it is when you want to update the BIOS. After updating the BIOS, you should immediately re-enable it to protect it against viruses.
Chassis Intrusion
The field enables or disables the feature of recording the chassis intrusion status
and issuing a warning message if the chassis is once opened. To clear the warning
message, set the field to [Reset]. The setting of the field will automatically return to

Onboard Peripherals Configuration
Spread Spectrum
When the motherboard’s clock generator pulses, the extreme values (spikes)
of the pulses create EMI (Electromagnetic Interference). The Spread Spectrum
function reduces the EMI generated by modulating the pulses so that the spikes
of the pulses are reduced to flatter curves.
Important
1.If you do not have any EMI problem, leave the setting at [Disabled] for
optimal system stability and performance. But if you are plagued by EMI,
select the value of Spread Spectrum for EMI reduction.
2.The greater the Spread Spectrum value is, the greater the EMI is reduced,
and the system will become less stable. For the most suitable Spread
Spectrum value, please consult your local EMI regulation.
3.Remember to disable Spread Spectrum if you are overclocking because
even a slight jitter can introduce a temporary boost in clock speed which
may just cause your overclocked processor to lock up.
Onboard LAN Boot ROM
The setting enables/disables the initialization of the onboard LAN Boot ROM
during bootup. Selecting [Disabled] will speed up the boot process.
