Handling Precautions

Warning:

1. Static electricity may cause damage to the integrated circuits on

the motherboard. Before handling any motherboard outside of its
protective packaging, ensure that there is no static electric charge
in your body.

2. There is a danger of explosion if the battery is incorrectly
replaced. Replace only with the same or an equivalent type
recommended by the manufacturer.

3. Discard used batteries according to the manufacturer’s
instructions.

4. Never run the processor without the heatsink properly and firmly

attached. PERMANENT DAMAGE WILL RESULT!

Observe the following basic precautions when handling the motherboard
or other computer components:

n Wear a static wrist strap which fits around your wrist and is

connected to a natural earth ground.

n Touch a grounded or anti-static surface or a metal fixture such as a

water pipe.

n Avoid contacting the components on add-on cards, motherboards,

and modules with the golden fingers connectors plugged into the
expansion slot. It is best to handle system components by their
mounting brackets.

The above methods prevent static build-up and cause it to be discharged
properly.

connector, 1 VGA connector, 1 SPDIF_OUT connector , 1 optional LAN, 1 PS/
2 mouse a nd keyboard connector, 6 USB 2.0 ports (4 ja cks a nd 1 pinhea der) a nd
1 media connector (Line-In, Line-Out*, M ic-In, front audio pinheader).

* The audio features of this mainboar d do not have an amplifier, an a ctive speaker is a
must.

Other key features are Remote On/Off, Auto Power Failure Recovery, inte­grated temperature monitoring and system fan control. Included also is a CD
with enhanced supporting drivers containing a few bundled soft-ware solu­tions.

on the various jumper settings on your mainboard.

To set up your computer, you must complete the following steps:

n

Step 1 - Set system jumpers/switches

n

Step 2 - Install memory modules

n

Step 3 - Install the Central Processing Unit (CPU)

n

Step 4 - Install expansion cards
Step 5 - Connect ribbon cables, cabinet wires, and power supply

n
n

Step 6 - Set up BIOS software

n

Step 7 - Install supporting software tools

WARNING: Excessive torque may damage the mainboard. When
using an electric screwdriver on the mainboard, make sure that
the torque is set to the allowable range of 5.0 ~ 8.0kg/cm.

Mainboard components contain very delicate Integrated Circuit
(IC) chips. To prevent static electricity from harming any of the
sensitive components, you should follow the following precau­tions whenever working on the computer:

1. Unplug the computer when working on the inside.

2. Hold components by the edges and try not to touch the IC

||||chips, leads, or circuitry.

3. Wear an anti-static wrist strap which fits around the wrist.

4. Place components on a grounded anti-static pad or on the bag
that came with the component whenever the components are
separated from the system.

VI39C Mainboard Manual

3). CPU Fan Installation

This connector is linked to the CPU fan. Without sufficient air circulation, the

CPU may overheat resulting in damage to both the CPU and the mainboard.

Damage may occur to the mainboard and/or the CPU fan if these pins are
used incorrectly. These are not jumpers, do not place jumper caps over these
pins.

1). Set System Jumpers

Jumpers are used to select the operation modes for your system. Some jump­ers on the board have three metal pins with each pin representing a different
function. A 1 is written besides pin 1 on jumpers with three pins. To set a
jumper, a bla ck cap containing metal contacts is pla ced over the jumper pin/s
according to the required configuration. A jumper is said to be shorted when
the black cap has been placed on one or two of its pins.

NOTE: Users are not encouraged to change the jumper settings
not listed in this manual. Changing the jumper settings improperly
may adversely affect system performance.

Clear CMOS: CLR_CMOS

The CMOS RAM is powered by the onboard button cell battery . To clear the
RTC data: (1) Turn of f your computer (2) Place the jumper ca p onto the pinpair
2-3 at least 6 seconds to clear CMOS (3) Place the jumper cap onto the pinpair
1-2 to Normal (4) Turn on your computer until CMOS checksum error appears
(5) Hold down the Delete key when boots (6) Enter the BIOS Setup to re-enter
user preferences.

Installation Procedures

2). Install Memory Modules

1. Locate the DIMM slots on the mainboard.

2. Install the DIMM straight down into the DIMM slot using both hands.

3. The clip on both ends of the DIMM slot will close up to hold the DIMM
in place when the DIMM reaches the slot bottom.

Press the clips with both hands to remove the DIMM.

2 - 5

VI39C Mainboard Manual

3). Install the CPU

The mainboard has built-in Switching Voltage Regulator to support CPU Vcore
autodetection. That is, It has the ability to detect and recognize the CPU
voltage, clock, ratio and enables users to set up the CPU frequency from the
BIOS Setup Screen. Users can adjust the frequency through Frequency /
V oltage Control of the BIOS Setup Screen.

CAUTION:

1. The heatsink and fan you installed must be approved by CPU

|||||manufactories.

2. The mainboard must be placed on a solid place to avoid shaking

|||||while install the heatsink and fan on the board.

3. The heatsink must be contact with the CPU top tightly.

4. Never run the processor without the heatsink properly and firmly

attached. PERMANENT DAMAGE WILL RESUL T!

When you install the CPU on this mainboard, please use a power supply that
designed and ma nufactured only for your CPUs use. Your CPU fansink com­bined with its retention module must be completely closed and firmly attached
on the top of the processor.

2 - 6

Installation Procedures

T o install the CPU, do the following:

1 . Lift the lever on the side of the CPU socket.

2. Handle the chip by its edges and try not to touch any of the pins.

3 . Place the CPU in the socket. Do not force the chip. The CPU should slide

easily into the socket.

4 . Swing the lever to the down position to lock the CPU in place.
5 . Place the cooling fan with heatsink on top of the installed CPU.

NOTE: Users The CPU installing procedures should be:

1. Insert the CPU (with its fansink and retention module) on the
socket.

2. Connect the 20-pin plug of the power supply

3. Connect the 4-pin plug of the power supply.
To remove the processor, please do it in reverse order.

4). Install Expansion Cards

This section describes how to connect an expansion card to one of your
system expansion slots. Expansion cards are printed circuit boards that, when
connected to the mainboard, increase the capabilities of your system. For
example, expansion cards can provide video and sound capabilities. The
mainboard features one AGP and three PCI bus expansion slots.

CAUTION: Make sure to unplug the power supply when adding or
removing expansion cards or other system components. Failure to
do so may cause severe damage to both the mainboard and
expansioncards.
Always observe static electricity precautions.
Please read Handling Precautions at the start of this manual.

2 - 7

VI39C Mainboard Manual

T o install an expansion card, follow the steps below:

1. Remove the computer chassis cover and select an empty expansion
slot.

2. Remove the corresponding slot cover from the computer chassis.
Unscrew the mounting screw that secures the slot cover and pull
the slot cover out from the computer chassis. Keep the slot cover
mounting screw nearby.

3 . Holding the edge of the peripheral card, carefully align the edge

connector with the expansion slot.

4. Push the card firmly into the slot. Push down on one end of the
expa nsion card, then the other . Use this rocking motion until the a dd–
on card is firmly seated inside the expansion slot.

5. Secure the board with the mounting screw removed in Step 2. Make
sure that the card has been placed evenly and completely into the
expansion slot.

6 . Replace the computer system’s cover.

7 . Setup the BIOS if necessary .

8. Install the necessary software drivers for the expansion card.
