Step 3.
Set Jumpers
The default jumper settings have been set for the common usage standard of
this mainboard. Therefore, you do not need to reset jumpers unless you
require special adjustments as any of following cases:
1. Clear CMOS
2. Make BIOS write protected
3. Power on system through keyboard or USB devices
4. Enable onboard audio CODEC
For first-time DIY system builders, we recommend that you should not
change the default jumper settings if you are not totally familiar with
mainboa rd configuration procedures. The factory-set default settings are
tuned for optimum system performa nce. For the advanced users who
wish to c ustomize their system, section 3.2 Jumper Settings will provide
the detailed informa tion on how to configure your mainboard ma nually.
Step 4
Install Internal Peripherals in System Case
Before you install and connect the mainboard into your system case, we
recommend tha t 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 connection 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, must
have jumpers on Master or Slave mode depending on your willing to
install more than one device for each kind.
2. Connect IDE cable and FDD cable to the back panel of the internal
peripheral devices. Note that the cable should be oriented with its
colored stripe (usually in red or magenta) connected to pin#1 both on
the mainboard IDE or FDD connector and on the device as well.
17
3. Connect an available power cable through 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.
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 the proper mounting holes, position the studs between
the fra me of chassis and the mainboard. The studs are used to fix the
mainboa rd and to keep a certain distance between the system chassis
and the mainboa rd, in order to a void any electrical short between the
board and the metal frame of 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 a ble to find 4 or more
attachment points to install mounting studs and fix the
mainboard. If there a ren’t enough matching holes, then make sure
to install at lea st 4 mounting studs to ensure proper attachment of
the mainboa rd.
18
Step 6
Connect Front Panel S witches/LEDs/Speaker
You can find there are several different cables already existing in the system
case and originati ng 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 11
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 conta ins 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 c an also add an extended partition if your primary
pa rtition does not use all of the available ha rd disk space. If you
choose to add an extended partition, you will have to create one or
more logic al partitions to occupy all the spac e available in the extended partition. The FDISK utility will assign a drive letter (i.e., C:,
D:, E:,...) to ea ch partition which will be shown in the FDISK progra m.
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 parti tions 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. Set up the complete operating system according to your OS installation
guide.
24
Step 12
Install Drivers & S oftware Components
Please note that all the system utilities and drivers are designed for Win 9x/
2000/ME/NT operating systems only. Make sure your operating system is
already installed before running the driver installation CD-ROM programs.
1. Insert the AT31 bundled CD-ROM into your CD-ROM drive. The
auto-run program will display the driver main installation window
on screen .
2. Choose " Install Mainboard Software" and complete the installation.
3. Return to the SHUTTLE MAINBOARD SOFTWARE SETUP screen.
4. Choose "Install Audio Device Software" and complete the
installation.
5. Return to the main installation window and exit from the auto-run
drivers installation program.
25
3.2 Jumper Settings

Several hardwa re settings are made through the use of jumper caps to
connect jumper pins to the mainboa rd. Pin #1 is loc ated at any corner of
each jumper; you just find a location with pin#1 marked. There are several
types of pin1# shown a s below:
3-pin and multi-pin (>3) jumpers are shown as follows:
Pin #1 to the left:
Pin #1 on the top:
Pin #1 to the right:
