Chapter 2 Hardware Setup
2.1 Choosing a Computer Chassis
• Choose a chassis big enough to install this mainboard.
• As some features for this mainboard are implemented by cabling connectors on the
mainboard to indicators and switches or buttons on the chassis, make sure your chassis
supports all the features required.
• If there is possibility of adopting some more hard drives, make sure your chassis has
sufcient power and space for them.
• Most chassis have alternatives for I/O shield located at the rear panel. Make sure the I/O
shield of the chassis matches the I/O port conguration of this mainboard. You can nd
an I/O shield specically designed for this mainboard in its package.
2.2 Installing Mainboard
Most computer chassis have a base with many mounting holes to allow the mainboard to
be securely attached, and at the same time, prevent the system from short circuits. There
are two ways to attach the mainboard to the
chassis base: (1) with studs, or (2) with spacers.
Basically, the best way to attach the board is with
studs. Only if you are unable to do this should you
attach the board with spacers. Line up the holes on
the board with the mounting holes on the chassis.
If the holes line up and there are screw holes, you
can attach the board with studs. If the holes line
up and there are only slots, you can only attach with
spacers. Take the tip of the spacers and insert them
into the slots. After doing this to all the slots, you can slide the board into position aligned
with slots. After the board has been positioned, check to make sure everything is OK before
putting the chassis back on.
To install this mainboard:
1. Locate all the screw holes on the mainboard and the chassis base.
2. Place all the studs or spacers needed on the chassis base and have them tightened.
3. Face the mainboard’s I/O ports toward the chassis’s rear panel.
4. Line up all the mainboard’s screw holes with those studs or spacers on the chassis.
5. Install the mainboard with screws and have them tightened.
The mainboard and its component layouts illustrated in this chapter were
based mainly on model “
NF520LE
(V1.0)”, unless specically stated.
Always power off the computer and unplug the AC power cord before adding or removing
any peripheral or component. Failing to do so may cause severe damage to your
mainboard and/or peripherals. Plug in the AC power cord only after you have carefully
checked everything.
To prevent shorting the PCB circuit, please REMOVE the metal studs or spacers if they are
already fastened on the chassis base and are without mounting-holes on the mainboard to
align with.

1. Please make sure that the mainboard supports the CPU.
2. Please take note of the one indented corner of the CPU. If you install the CPU in the wrong
direction, the CPU will not insert properly. If this occurs, please change the insert direction
of the CPU.
3. Please add an even layer of heat sink paste between the CPU and CPU cooler.
4. Please make sure the CPU cooler is installed on the CPU prior to system use, otherwise
overheating and permanent damage of the CPU may occur.
5. Please set the CPU host frequency in accordance with the processor specications. It is not
recommended that the system bus frequency be set beyond hardware specications since
it does not meet the required standards for the peripherals. If you wish to set the frequen-
cy beyond the proper specications, please do so according to your hardware
specications including the CPU, graphics card, memory, hard drive, etc.
2.3.1 Installation of the CPU

2.3.2 Installation of the CPU Cooler
For proper installation, please kindly refer to the instruction manuals of your CPU Cooler.
2.4 Installation of Memory Modules
This mainboard provides four 240-pin DDRII (Double Data Rate) DIMM slots, and supports
Dual Channel Memory Technology. For dual channel conguration, you always need to install
two identical (the same brand, speed, size and chip-type) memory modules in the DDRII
DIMM slots to activate Dual Channel Memory Technology. Otherwise, it will operate at single
channel mode.
To reach the performance of Dual Channel DDR2, the following rules must be obeyed:
For 2-DIMM dual-channel installation:
Populate DIMM modules of the same type and size on slots [DIMM1]+[DIMM2], or slots
[DIMM3]+[DIMM4](NF520LE(V3.0) not supports).
For 4-DIMM dual-channel installation:
Populate 2 DIMM modules of the same type and size on slots [DIMM1]+[DIMM2], and
another 2 DIMM modules of the same type and size on slots [DIMM3]+[DIMM4] .
[DIMM1] and [DIMM2] slots are made of the same color.
[DIMM3] and [DIMM4] are made of another same color.
To install system memory:
1. Power off the computer and unplug the
AC power cord before installing or
removing memory modules.
2. Locate the DIMM slot on the board.
3. Hold two edges of the DIMM module
carefully, keep away from touching its
connectors.
4. Align the notch key on the module with
the rib on the slot.
5. Firmly press the module into the slots until the ejector tabs at both sides of the slot
automatically snap into the mounting notch. Do not force the DIMM module in with extra
force as the DIMM module only ts in one direction.
6. To remove the DIMM modules, push the two ejector tabs on the slot outward
simultaneously, and then pull out the DIMM module.
Static electricity can damage the electronic components of the computer or optional
boards. Before starting these procedures, ensure that you are discharged of static
electricity by touching a grounded metal object briey.

Chapter 4 BIOS Setup Utility
BIOS stands for Basic Input and Output System. It was once called ROM BIOS when it was
stored in a Read-Only Memory (ROM) chip. Now manufacturers would like to store BIOS in
EEPROM which means Electrically Erasable Programmable Memory. BIOS used in this series
of mainboard is stored in EEPROM, and is the first program to run when you turn on your
computer.
BIOS performs the following functions:
1. Initializing and testing hardware in your computer (a process called "POST", for Power On
Self Test).
2. Loading and running your operating system.
3. Helping your operating system and application programs manage your PC hardware by
means of a set of routines called BIOS Run-Time Service.
4.1 About BIOS Setup
BIOS Setup is an interactive BIOS program that you need to run when:
1. Changing the hardware of your system. (For example: installing a new Hard Disk etc.)
2. Modifying the behavior of your computer. (For example: changing the system time or date,
or turning special features on or off etc.)
3. Enhancing your computer's behavior. (For example: speeding up performance by turning
on shadowing or cache)
4.2 To Run BIOS Setup
First access BIOS setup menu by pressing <DEL> key after “POST” is complete (before OS is
loaded). BIOS will then display the following message:
4.3 About CMOS
CMOS is the memory maintained by a battery. CMOS is used to store the BIOS settings you
have selected in BIOS Setup. CMOS also maintains the internal clock. Every time you turn
on your computer, the BIOS Looks into CMOS for the settings you have selected and
congures your computer accordingly. If the battery runs out of power, the CMOS data will
be lost and POST will issue a “CMOS invalid” or “CMOS checksum invalid” message. If this
happens, you have to replace the battery and check and congure the BIOS Setup for the
new start.
4.4 The POST (Power On Self Test)
POST is an acronym for Power On Self Test. This program will test all things the BIOS does
before the operating system is started. Each of POST routines is assigned a POST code, a
unique number which is sent to I/O port 080h before the routine is executed.
