Step 1
Install the CPU:
1. Locate the CPU ZIF (Zero Insertion Force) socket on the upper-right
sector of your mainboard (between the back-panel connectors and the
DIMM memory slots).
2. Pull the CPU ZIF socket lever slightly sideways away from the socket
to unlock the lever, and then bring it to an upwardly vertical position.
3. Place your AMD 462 Athlon/Duron processor in the socket A. Note that
the CPU's edges have been purposely designed non-symmetrically to pre-
vent from inserting the processor in the wrong direction. The following
diagram demonstrates the correct placement of the CPU in the ZIF socket.
You can see that the two blunt-edged corners should face towards the
socket-lever.
4. Slightly push the AMD 462 Athlon/Duron processor into the socket without
applying excessive force while making sure there is no gap between CPU
and socket. Then lower the socket-lever all the way down to its horizontal
position and lock it to secure the CPU in place.
5. The AMD 462 Athlon/Duron processor requires a set of heatsink/fan to
ensure proper cooling of the processor. If heatsink/fan have not been
already mounted on your CPU, you must purchase the heatsink/fan sepa-
rately and have it installed. Plug the cable through the heatsink/fan in the
CPU fan power connector located nearby. Note that there are several types
of CPU fan connectors. Normally, if your mainboard supports the hard
ware monitoring function, a 3-pin fan power connector should allow your
system to detect the CPU fan's speed. The CPU fan can also run with a
2- pin fan power connector, however, detection of CPU fan's speed is not
supported. Another type of CPU fan may feature a large 4-pin fan power
connector, which does not support CPU fan's speed detection and must
be directly connected to the system's power supply unit. Please refer to
the following diagram.

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 in any of the
following cases:
1. Clear CMOS
2. BIOS Write Protect
For first-time DIY system builders, we recommend that you do not change the
default jumper settings if you are not totally familiar with mainboard configu-
ration procedures. The factory-set default settings are tuned for optimum
system performance. For the advanced users who wish to customize their
system, section 3.2 Jumper Settings will provide detailed information on how
to configure your mainboard manually.
Step 3.
Install DDR or SDR SDRAM System Memory
To insert memory module(s) in any one or two DIMM slot(s). Please note
that modules are directional and will not go in the DIMM slots unless prop-
erly 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.
SDR SDRAM DDR SDRAM

- 14 -
Step 4
Install Internal Peripherals in System Case
Before you install and connect the mainboard into your system case, we
recommend that you first assemble all the internal peripheral devices into the
computer 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 de-
scribed below.
To install IDE & FDD drives, follow this procedure:
1. Set the required jumpers on board each device according to the
instructions provided by the manufacturer. (IDE devices, HDD, and
CD-ROM have to set jumpers on Master or Slave mode depending
on your willing to install more than one device for each kind.)
2. Connect IDE cable and FDD cable on the back-panel of the internal
peripheral devices to the corresponding headers on board. Note that the
cable should be oriented with its colored stripe (usually in 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 through your system power supply unit
to the back-panel of each peripheral device. Note that the power cable
is directional and cannot fit in if it is not properly positioned.

- 15 -
Step 5
Mount the Mainboard on the Computer Chassis
1. You may find that there are a lot of different mounting hole positions both
on your computer chassis and on the mainboard. To choose a correct
mounting hole, the key point is to keep the back-panel of the mainboard
in a close fit with your system case, as shown below.
2. After deciding on the proper mounting holes, position the studs be tween
the frame of chassis and the mainboard. The studs are used to fix the
mainboard and to keep a certain distance between the system chassis and
the mainboard, in order to avoid any electrical shortage between the
board and the metal frame of chassis. (If your computer case is already
equipped with mounting studs, you will need to tighten screws to attach
the mainboard.)
Note:Note:
Note:Note:
Note: Inmost computer housings, you will be able to find 4 or more
attachmentpoints toinstall mounting studs and fixthe mainboard.
If there aren't enough matching holes, then make sure to install at
least 4 mounting studs to ensure proper attachment of the
mainboard.

- 16 -
Step 6
Connect Front-Panel Switches/LEDs/Speaker/USB connectors
You can find there are several different cables already existing in the system
case and originating from the computer's front-panel devices (HDD LED,
Power LED, Reset Switch, PC Speaker, or USB devices etc.) These cables
serve to connect the front-panel switches, LEDs, USB connectors to the
mainboard's front-panel connectors group (JP7, JP4 and JP5), as shown
below.
