Step 1
CPU Installation:
This mainboard supports Intel Pentium 4/Celeron Socket 478 series CPU.
Please follow the steps as follows to finish CPU installation.
Note the CPU orientation when you plug it into CPU socket.
1. Pull up the CPU socket lever to 90-degree angle.
2. Locate Pin 1 in the socket and look for a black dot or cut edge on the CPU
upper interface. Match Pin 1 and cut edge, and insert the CPU into the
socket. CPU Pin 1 and cut edge
CPU socket lever up to
90-degree angle

- 13 -
3. Press down the CPU socket lever and finish CPU installation.
Note: The CPU might be damaged if you do not match the CPU
socket Pin 1 and cut edge well.
4. Intel Pentium 4/Celeron processor requires a set of heatsink and fan to cool
downthe processor.Youneed topurchase aheatsink andfanif theyare not
bundled with your CPU. Required is that install the set and plug its cable
in the CPU fan power connector. Note that there are kinds of CPU fan
connectors. Normally, if your mainboard supports a hardware monitoring
function,a 3-pinfan powerconnector canhave yoursystem detectthe CPU
fan's speed. A CPU fan with a 2-pin or 4-pin fan power connector does not
support the detection of the CPU fan's speed, and must directly be con-
nected to the system's power supply unit.

- 14 -
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:
Clear CMOS setting
BIOS written protection
CPU FSB setting
For first-time DIY system builders, we recommend that you not change the
default jumper settings if you are not totally familiar with the mainboard
configuration procedures. The factory-set default settings are tuned for opti-
mum system performance. For the advanced users who wish to customize
their system, section3.2 Jumper Settings will provide detailed information
on how to configure your AV42 mainboard manually.
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 slot, lift the clips of both sides of the DIMM slot to lock the module in
place.
DDR SDRAM

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 each device according to the instructions
provided 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
peripheral 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
directional and cannot fit in if not properly positioned.

- 16 -
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
correct mounting holes, 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 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 attach-
ment points to install mounting studs and then fix the mainboard. If
there are not enough matching holes, then make sure to install at
least 4 mounting studs to ensure proper attachment of the main-
board.

- 17 -
Step 6
Connect Front-Panel LEDs/Switch/USBs
You can find there are several different cables already existing in the system
case and originating from computer's front-panel devices (MSG LED, HDD
LED, PWR BTN, RST switch, or USB devices etc.). These cables serve to
connect the front-panel LEDs, switch, and USB connectors to mainboard's
front-panel connector groups (Panel and USB2&3), as shown below.
1. Green-LED and Power-LED (MSG LED)
2. HDD-LED (HDD LED)
3. ATX Soft Power On/Off (PWR BTN)
4. Hardware Reset Switch Button (RST)
