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 banks).

2. Pull the CPU ZIF socket lever slightly sideways away from the socket
to unlock the lever, then bring it to an upward vertical position.

3. Place your PPGA/FC-PGA 370 processor in the ZIF socket. Note that
the CPU’s edges have been purposely designed non-symmetrical to
prevent from inserting the processor in the wrong direction. The follow
ing diagram demonstrates the correct placement of the CPU in the ZIF
socket. You can see that the two blunt-edged corners should face to
wards the socket-lever.

4. Slightly push the PPGA/FC-PGA 370 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 PGA 370 CPU requires a set of heatsink/fan to ensure proper
cooling of the processor. If not already mounted on your CPU, you must
purchase the heatsink/fan separately and have it installed. Plug the cable
from the heatsink/fan to 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 connect directly to the system’s power
supply unit.

- 11 -

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 in any of the
following cases:

1. Over-clock your CPU

2. Clear CMOS

3. Disable the on board audio before installing an add-on sound card

For first-time DIY system builders, we recommend that you do not change the
default jumper settings if you are not totally familiar with 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 SDRAM System Memory

To install memory, insert SDRAM memory module(s) in any one, two or three
DIMM banks. Note that SDRAM modules are directional and will not go in
the DIMM slots unless they are properly oriented. After the module is fully
inserted into the DIMM socket, lift the clips of both sides of the DIMM bank to
lock the module in place.

- 12 -

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. 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.

- 13 -

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 a
correct mounting hole, 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 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 fix the mainboard.
If there aren’t enough matching holes, then make sure to install at
least 3 mounting studs to ensure proper attachment of the
mainboard.

- 14 -

Step 6

Connect Front Panel Switches/LEDs/Speaker

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, PC Speaker, etc.) These cables serve to connect the
front-panel switches and LEDs to the mainboard’s front-panel connectors
group, 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: 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 device your
HDD into partitions no larger than 2.1GB each.

4. Now, use the FORMAT utility to format all the partitions you’ve created.
When formatting the primary partition (C:), make sure to use the
FORMAT 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.

- 22 -

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 Windows 9x operating system is
already installed before running the drivers installation CD-ROM programs.

1. Insert the AV18 bundled CD-ROM into your CD-ROM drive. The
auto-run program will display the drivers main installation window on
screen .

2. Choose to " Install Mainboard Software" and complete it.

3. Return to the SHUTTLE MAINBOARD SOFTWARE SETUP screen.

4. Choose to "Install Audio Device Software" and complete it.

5. Return to the SHUTTLE MAINBOARD SOFTWARE SETUP screen.

6. Choose to "Install VIA Hardware Monitor" and complete it.

7. Return to the main installation window and exit the auto-run drivers
installation program.

- 23 -

3.2 Jumper Settings

Several hardware settings are made through the use of jumper caps to con­nect jumper pins on the mainboard. Pin #1 is located at any corner of each
jumper, you just find a white right angle on the mainboard, that's pin 1#.
There are several types of pin1# shown as below:

3-pin and multi (>3) pin jumpers shown as following:
Pin #1 on the left:

Pin #1 on the top:

Pin #1 on the right:

Jumpers with two pins are shown as for Close [On] or for
Open [Off]. To Short jumper pins, simply place a plastic jumper cap 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 handleing this equipment.
