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 AthlonXP/Athlon/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/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 AthlonXP/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 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 hardware 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

The default jumper settings have been set for the common usage standard of
this mainboard. Therefore, you need not to reset the jumpers unless you re­quire special adjustments as the following case:

Clear CMOS Setting

For first-time DIY system builders, we recommend that you not change the
default jumper settings if you are not quite familiar with the mainboard con­figuration procedures. The factory-set default settings are tuned for optimum
system performance. For advanced users who prefer to customize their sys­tem, section 3.2 Jumper Settings provides the detailed information on how
to configure your mainboard manually.

Step 3

Install DDR SDRAM System Memory

To install memory, insert DDR SDRAM memory module(s) in the DIMM
banks. Note that DDR 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.

DDR SDRAM

Step 4

Install Internal Peripherals in System Case

Before you place 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.

To install IDE & FDD drives, follow these procedures:

1. Set the required jumpers on each device according to the instructions pro­vided by the manufacturer. (IDE, 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 the 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 of the IDE or FDD connector on the mainboard 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 there are a lot of mounting holes on your computer chassis
and mainboard. To match the holes on both properly, the key point is to
make the back panel of the mainboard in a close fit with your system case,
as shown below.

2. Position the studs between the chassis and the mainboard. The studs are
used to fix the mainboard and to keep a certain distance between them,
for avoiding any electrical shorts in-between.

(If your computer case is already equipped with mounting studs, you need
to tighten the screws to attach the mainboard.)

Note: In most computer housings, you can find 4 or more holes to place

studs for fixing the mainboard. If there aren't enough matching holes,
screw at least 4 studs to ensure the proper attachment of the main­board.

- 15 -

Step 6

Connect Front Panel LEDs/Switches/USBs

You can find there are several cables existing in the system case and originat­ing from the front panel devices (HDD LED, Green LED, Reset switch, and
USB devices etc.). These cables serve to connect the front panel LEDs,
switches, and USB connectors to JP13 and JP5/JP6/JP10, as shown below.

1. HDD LED (HLED)

2. Green LED/Power LED
(GLED/PWR LED)

3. Hardware Reset Switch (RST)

4. ATX Soft Power On/Off (PWON)

Step 12

System Boot Up For the First-Time

To ensure your system completedly and correctly installed, please refer to the
above installation steps once again before first booting up your system.

1. Insert a system-bootable floppy disk (DOS 6.2X, Windows 9X/NT, or
others), which contains the FDISK and FORMAT utilities.

2. Turn on the system power.

3. First, you need to 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 shown in

the FDISK program. After the FDISK procedure, reboot your system by
using the same 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 any par­titions no larger than 2.1GB.

4. Now, use the FORMAT utility to format all the partitions you've created.
When formatting the primary partition (C:), key in the command, "FOR­MAT C:/S."

Note: FORMAT C:/S can transfer all the necessary system files into the pri-

mary partition of your hard disk. Afterwards, 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.

- 22 -

Step 13

Install Drivers & Software Components

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

1. Insert the FX43G bundled CD-ROM into your CD-ROM drive. The auto-

run program will display the main installation window on screen.

2. Choose "Install Mainboard Software."

3. Choose "Install VIA 4in1 Driver" and complete it.

4. Choose "Install VIA VGA Driver" and complete it.

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

6. Choose "Install VIA RAID Driver" and complete it.

7. Choose "Install Realtek LAN Driver" and complete it.

8. Choose "Install Realtek Audio Driver" and complete it.

9. Exit from the autorun drivers installation program.

ATX Power Supply Connectors (JP12/J2)

This motherboard uses 20-pin ATX power header (ATXPWR, JP12), and
comes with the other one header (ATX12V, J2). Please make sure you plug
each in the right direction. It is essential to have these two power supply
connectors plugged or your system won't boot up.

A traditional ATX system remains in the power-off stage when AC power re­sumes from power failure. However, it is inconvenient for a network server or
workstation if there is not an UPS to execute power-on. Thus, this motherboard
supports an AC Power Auto Recovery function to solve this problem. You may
enable the function, "PWRON After PWR-Fail," in the sub-menu of "Power
Management Setup" within the BIOS setup program.

Note 1: The ATX power connector is directional and will not go in

unless the guides match perfectly, making sure that pin#1 is
properly positioned.

Note 2: Make sure the latch of the ATX power connector clicks into

place to ensure a solid attachment.

Note 3: Your ATX power supply must be supplied to ACPI+5V stand-

by power and at least 720mA compatible.

Note 4: Make sure your power supply have enough power for higher

speed processor installed.

Fan Speed Up When CPU Temp

Enables 3 phase smart controls to the Selected fan. This feature ranges
from 40 0C to 52 0C, in an increment of 4 0C.
Ø The choice: 40 0C, 44 0C, 48 0C, or 52 0C.

If actual CPU temp (reported by BIOS) stays below 48 0C 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 preselected 48 0C
temperature threshold, then CPU fan speed will automatically engage
into normal mode (2nd phase) of about 3000 RPM and cool down
the CPU temperature. When the CPU temperature drops back below
the 48 0C temperature threshold, CPU fan speed will again automati­cally shift back to the quiet mode (1st phase) to reduce fan noise level.

Fail-safe mode (3rd phase) Variable Fan Speed and CPU temperature
Control is as predefined at 52 0C. Where in the event of system and
CPU operating under extreme working conditions, and if CPU tempera­ture is raised above 52 0C then the SMART BIOS will engage the CPU
fan in Fail-safe mode to rotate at about 3500 RPM. Please note that the
higher fan speed, the fan cooler will be become slightly noiseier to
compensate for the increase in CPU temperature.
