Step 1

Blank

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 AthlonXP/Duron processor in the socket A. Note that the
CPU's edges have been purposely designed non-symmetrically to prevent
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 AthlonXP/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 AthlonXP/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 sepa­rately and have it installed. Plug the cable throught 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 2­pin 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 any of the
following cases:

Clear CMOS
FSB setting
BIOS written protection

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 opti­mum system performance. For the advanced users who wish to customize
their system, section
how to configure your FX41 mainboard manually.

3.2 Jumper Settings

will provide detailed information on

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

- 13 -

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.

- 14 -

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 attach­ment 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 main­board.

- 15 -

Step 6

1

Connect Front Panel Switches/LEDs/USBs

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, or USB devices etc.). These cables serve to connect
the front-panel switches, LEDs, and USB connectors to the mainboard's front­panel connector groups (JP13 and JP5&6), as shown below.

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 parti­tion 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:

4. Now, use the FORMAT utility to format all the partitions you've created.

Note:

5. Install all the necessary drivers for CD-ROM, Mouse, etc.

6. Setup the complete operating system according to your OS installation

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.

When formatting the primary partition (C:), make sure to use the FORMAT
C: /S command.

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.

Step 13

Install Drivers & Software Components

Please note that all the system utilities and drivers are designed for Win 9x/
2000/ME/XP/NT operating systems only. Make sure your operating system is
already installed before running the driver's installation CD-ROM programs.

1. Insert the bundled FX41 CD-ROM into your CD-ROM drive. The autorun
program will display the driver's main installation window on screen.

2. Choose "Install VIA Chipset Driver" and complete it.

3. Choose "Install VGA Device Driver" and complete it.

4. Choose "Install Audio Driver" and complete it.

5. Choose "Install USB2.0 Driver" and complete it.

6. Choose "Install LAN Driver" and complete it.

7. Exit from the autorun driver's installation program.

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.

5 BIOS SETUP

FX41 mainboard's BIOS ROM has a built-in Setup program that allows users
to modify the basic system configuration. This information is stored in bat­tery-backed RAM so that it retains the Setup information even if the system
power is turned off.

The system BIOS is managing and executing a variety of hardware related
functions in the system, including:

System date and time
Hardware execution sequence
Power management functions
Allocation of system resources

the original PC AT bus specification; PCI/ISA PnP for devices is compli­ant with the Plug-and-Play standard whether designed for PCI or ISA
bus architecture.

Ø The choice: PCI Device or Reserved.

PCI/VGA Palette Snoop

It determines whether the MPEG ISA/VESA VGA Cards can work with
PCI/VGA or not. If you have MPEG ISA/VESA VGA Cards and PCI/
VGA Card worked, Enable this field. Otherwise, please Disable it.

Ø The choice: Enabled or Disabled.

Assign IRQ For VGA

This item allows the user to set VGA IRQ Routing table Enabled or
Disabled.

Ø The choice: Enabled or Disabled.

Assign IRQ For USB

This item allows the user the option to assign an IRQ to on-board USB
controller.

Since the on-board controller is always enabled, if no IRQ is assigned to
it, there will be a question mark report on the sytem device under
Windows95/98.

Ø The choice: Enabled or Disabled.

INT Pin 1/2/3/4 Assignment

This item defines each PCI slot IRQ assignment by manually, which
can avoid the IRQ share problem for some PCI card cannot share IRQ.

Ø The choice: Auto, 3, 4, 5, 7, 9, 10, 11, 12, 14, or 15.

 PC Health Status

CPU Fan AutoGuardian

This SMART Bios enableds you 3 phase Variable Fan Speed and CPU
temperature Control feature.

 The choice: Enabled or Disabled.

This feature is controlled via Bios, in which the CPU fan rotational
speed sensing/control is governed by CPU temperature setting pre­selected in Bios.

By default, "CPU Fan AutoGuardian" feature under PC Health Status
is disabled. To utilize the Smart Bios CPU Fan speed feature please
"Enabled" .

Note: Before manually modifying the CPU fan settings, please make

sure both fan connectors are plug into the correct fan connector
designations on the mainboard.

Enable you to choose one or both specific fan for further setting.
 The choice: Fan1, Fan2, Fan3, or Fan1 & Fan3.

Fan Speed Up When CPU Temp

Enable 3 phase smart control to the Selected fan. This feature ranges
from 40° C to 52° C, in an increment of 4° C. The default temperature
is at 48° C.

 The choice: 40° C, 44° C, 48° C, or 52° C.

Take our default Setting for example, 1st and 2nd phase Variable Fan
Speed and CPU temperature Control is as defined by "Fan Speed Up
When CPU Temp". If actual CPU temp (reported by Bios) stays below

48°C then CPU fan speed will run at a quiet mode (1st phase) of

approximately 2000 RPM.

But when the actual CPU temp goes above the pre-selected 48°C

temperature threshold, then CPU fan speed will automatically engage
into normal mode (2nd phase) of about 3000 RPM. Automated by the
Smart Bios feature, this increase of fan rotation speed will effectively
cool down the CPU temperature. And when the CPU temperature drops

back below the 48°C temperature threshold, CPU fan speed will again

automatically shift back to the quiet mode (1st phase) of about 2000 RPM
in order to reduce fan noise level.

- 72 -

Fail-safe mode (3rd phase) Variable Fan Speed and CPU temperature

Control is as predefined at 56°C. Where in the event of system and CPU

operating under extreme working conditions, and if CPU temperature is

raised above 56°C then the Smart Bios will engage the CPU fan in Fail-safe

mode to rotate at about 4500 RPM. Please note that the higher the fan
speed, the fan cooler will be become slightly noisier in order to com­pensate for the increase in CPU temperature.

Note: Please disable CPU Fan AutoGuardian feature, if you wish to use

other K7 cooler, allowing the CPU fan to run at its default speed.

Shutdown Temperature

Enable you to set the maximum temperature that system can
reachbefore powering down.

 The choice: 60° C/140° F, 65° C/149° F, 70° C/158° F, Disabled.
