(E) Notices for Assembling Computers:
1. Cases should be made of iron or other metal that has good electric conductivity.
2. Cylinders in a case should be made of metal, and as having a mainboard mounted
in a case, make sure screws are all utilized and fastened on a mainboard.
3. An I/O shielding should be contacted with I/O metallic parts of a mainboard.
4. Cables should appropriately be arranged and fixed in a case. Follow instructions:
Ø Leave IDE cables not crossed upon CPU and SDRAM;
Ø Leave power cables minimum in length, and not crossed upon a mainboard;
Ø Leave CPU fan cables minimum in length, and not near CPU;
Ø Leave cables on panels and other spare cables tied in a computer case.
5. Make sure an EMI shielding attached to a case has properly been installed.
6. Make sure a 5.25" and screws are fastened to an EMI shielding.
7. Make sure a case is closely in contact with EMI connected points.
8. Make sure there is no cleft in a case which is not deformed.
9. Make sure a PCI door is bound to a case.

Step 1
CPU Installation:
This mainboard supports Socket 775 Prescott/Tegas Processors (CPU).
To install, follow the steps outlined below. Note the CPU orientation carefully
when you insert it into the socket.
Caution :This 775 pin socket is fragile and easily damaged.
Always use extreme care when installing a CPU and limit the
number of times that you remove or change the CPU.
1. Remove the protective cover.
2. Unlock the socket lever and lift it to 90-degrees (be careful not to touch the
socket pins during this process).

- 13 -
3. Orientate the CPU and socket, aligning the yellow triangle on the corner of
the CPU with the triangle on the socket. Gently insert. Take care not to place
any sideways force on the CPU when inserting, as the socket is fragile and
easily damaged.
4. Lower the CPU socket lever and lock in place.
5. The Socket 775 processor requires a heat sink and cooling fan to run effi-
ciently, cool and stable. If you do not receive a bundled heat sink and fan
when you purchase you CPU, it is essential that you acquire one.
Note :The CPU might be damaged
if you do not match the CPU
socket Pin 1 and cut edge well.

Step 2.
Set Jumpers
This mainboard is jumperless! The default jumper settings have been set for the
common usage standard of this mainboard. Therefore, you do not need to reset
the jumpers unless you require special adjustments as any of the following cases:
1. Clear CMOS
For first-time DIY system builders, we recommend that you do not change the
default jumper settings if you are not totally familiar with the mainboard con-
figuration procedures. The factory-set default settings are tuned for optimum
system performance. For the advanced users who wish to customize their sys-
tem, section 3.2 Jumper Settings will provide detailed information on how to
configure your mainboard manually.
Caution: If you did not place the battery apropriately, which may cause
risk of explosion. please pefer to the related rule for the dis-
pose of used batteries.
Step 3
Install DDR SDRAM System Memory
To install memory, insert DDR SDRAM memory module(s) in DIMM slot(s).
Note that DDR SDRAM modules are directional and will not go in the DIMM
slots unless properly oriented. After the module is fully inserted into the DIMM
slots, lift the clips of both sides of the DIMM slot to lock the module in place.
Do not remove memory modules while DIMM LED is on. It might cause short
or other unexpected damages due to the 2.6V stand by voltage. Remove memory
modules only when AC Power cord is disconnected.

Step 4
Install Internal Peripherals in System Case
Before you install and connect the mainboard into your system case, we rec-
ommend that you first assemble all the internal peripheral devices into the com-
puter housing, including but not limited to the hard disk drive (IDE/HDD), floppy
disk drive (FDD), CD-ROM drive, and ATX power supply unit. This will greatly
facilitate in making the connections to the mainboard described below.
To install IDE & FDD drives, follow this procedure:
1. Set the required jumpers on each device according to the instructions pro-
vided by the manufacturer. (IDE devices, HDD, and CD-ROM, have to set
jumpers to Master or Slave mode depending on whether you install more
than one device of each kind.)
2. Connect IDE cable and FDD cable on the back-panel of the internal periph-
eral devices to the corresponding headers on board. Note that the cable
should be oriented with its colored stripe (usually red or magenta) connected
to pin#1 both on the mainboard IDE or FDD connector and on the device as
well.
3. Connect an available power cable from your system power supply unit to
the back-panel of each peripheral device. Note that the power cable is di-
rectional and cannot fit in if not properly positioned.

- 16 -
Step 5
Mount the Mainboard on the Computer Chassis
You may find that there are a lot of different mount-
ing hole positions both on your computer chassis
and on the mainboard. To choose correct mount-
ing holes, the key point is to keep the backpanel of
the mainboard in a close fit with your system
case.
After deciding on the proper mounting holes, po-
sition the studs between the frame of the chassis
and the mainboard. The studs are used to fix the
mainboard and to keep a certain distance between
the system's chassis and the mainboard, in order
to avoid any electrical shorts between the board
and the metal frame of the chassis.
(If your computer case is already equipped with mounting studs, you will
need to tighten screws to attach the mainboard.)
Note :In most computer housings, you will be able to find 4 or more
attachment points to install mounting studs and then fix the main-
board. If there aren't enough matching holes, then make sure to
install at least 4 mounting studs to ensure proper attachment of
the mainboard.
Step 6
Connect Front-Panel Switches/LEDs/
USBs/1394a/Aux-In/Mic-In/Line-Out
You can find there are several different cables
already existing in the system case and origin
atinting from the computer's front-panel devic
es (HDLED, GLED, USB4/5, Aux-In, Mic-In,
Line-Out, 1394a devices etc.) These cables
serve to connect the HDLED, GLED, USB4/5,
Aux-In, Mic-In, Line-Out or 1394a connectors
to the mainboard's front-panel connectors
group, as shown below.
