This section outlines how to install and configure your mainboard. Refer to the following
mainboard layout to help you to identify various jumpers, connectors, slots, and ports.
Then follow these steps designed to guide you through a quick and correct installation of
your system.
3.1 Step-by-Step Installation
Accessories Of AV41
- 11 -
Step 1
CPU Installation:
This mainboard supports Intel Pentium 4 Socket 478 series CPU. Please
follow the step as below to finish CPU installation.
Be careful of CPU orientation when you plug it into CPU socket.
1. Pull up the CPU socket level and up to 90-degree angle.
CPU socket level up to
90 degree
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, then insert the CPU into the
socket.

- 12 -
3. Press down the CPU socket level and finish CPU installation.
Note: If you do not match the CPU socket Pin 1 and CPU cut
edge well, it may damage the CPU.
- 13 -
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
2. BIOS 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 the
mainboard configuration 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 SDRAM System Memory
To install memory, insert SDRAM memory module(s) in any one or two or
three DIMM banks. Note that SDRAM modules are directional and will not
go in the DIMM banks if they are not properly oriented. After the module is
fully inserted into the DIMM bank, lift the clips of both sides of the DIMM
bank to lock the module in place.
- 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 described 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.
- 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
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 be
tween 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
chassis and the mainboard, in order to avoid any electrical shorts
between the board and the metal frame of the chassis. (If your com
puter 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
mainboard. If there arent enough matching holes, then make sure
to install at least 4 mounting studs to ensure proper attachment of
the mainboard.

Step 12
First Time System Boot Up
To assure the completeness and correctness of your system installation, you
may check the above installation steps once again before you boot up your
system for the first time.
1. Insert a bootable system floppy disk (DOS 6.2x, Windows 95/98/NT, or
others) which contains FDISK and FORMAT utilities into the FDD.
2. Turn on the system power.
3. First, you must use the FDISK utility to create a primary partition of the
hard disk. You can also add an extended partition if your primary parti-
tion does not use all of the available hard disk space. If you choose to
add an extended partition, you will have to create one or more logical
partitions to occupy all the space available to the extended partition. The
FDISK utility will assign a drive letter (i.e., C:, D:, E:,...) to each partition
which will be shown in the FDISK program. After FDISK procedure,
reboot your system by using the same system floppy disk.
Note: DOS 6.2x and Windows 95A can only support up to 2.1GB of
HDD partition. If you use the FDISK utility with one of the operating systems mentioned above, you can only install your HDD into
partitions no larger than 2.1GB each.
4. Now, use the FORMAT utility to format all the partitions youve created.
When formatting the primary partition (C:), make sure to use the FORM-
AT C: /S command.
Note: FORMAT C: /S can transfer all the necessary system files into the
primary partition of your hard disk. Then, your HDD will become
a bootable drive.
5. Install all the necessary drivers for CD-ROM, Mouse, etc.
6. Setup the complete operating system according to your OS installation
guide.
- 24 -
Step 13
Install Drivers & Software Components
Please note that all the system utilities and drivers are designed for Win
9x operating systems only. Make sure your operating system is already
installed before running the drivers installation CD-ROM programs.
1. Insert the AV41 bundled CD-ROM into your CD-ROM drive. The
auto-run program will display the drivers main installation window on
screen.
2. Select the "Install Mainboard Software" bar to run into sub-menu.
3. Choose "Install VIA Driver" and complete it.
4. Choose "Install AC97 Sound Driver" and complete it.
6. Return to the main installation window and exit from the auto-run
drivers installation program.
- 25 -
3.2 Jumper Settings
Several hardware settings are made through the use of mini jumpers to connect jumper pins on the mainboard. Pin #1 could be located at any corner
of each jumper, you just find the location with a white right angle which
stands for pin 1#. There are several types of pin 1# shown as below:
3-pin and multi (>3) pin jumpers shown as following:
Pin #1 to the left:
Pin #1 on the top:
Pin #1 to the right:
Pin #1 on the bottom:
Jumpers with two pins are shown as for Close [On] or for
Open [Off]. To Short jumper pins, simply place a plastic mini jumpers over
the desired pair of pins.
Caution!
1. Do not remove the mainboard from its antistatic protective packaging
until you are ready to install it.
2. Carefully hold the mainboard by its edges and avoid touching its
components. When putting the mainboard down, place it on top of its
original packaging film, on an even surface, and components side up.
3. Wear an antistatic wrist strap or take other suitable measures to prevent
electrostatic discharge (ESD) whenever handling this equipment.
