1INTRODUCTION
1.1 To Different Users
First-Time DIY System Builder
Welcome to the DIY world! Building your own computer system is not as diffi-
cult as you may think. To make your first computer DIY experience successful,
right from the start, we have designed the 3.1 Hardware Installation section
in a step-by-step fashion for all the first-time DIY system builders. Prior to instal-
lation, we also suggest you to read the whole manual carefully to gain a com-
plete understanding of your new Shuttle AB49/AB49N mainboard.
Experienced DIY User
Congratulate on your purchase of the Shuttle AB49/AB49N mainboard. You
will find that installing your new Shuttle AB49/AB49N mainboard is just easy.
Bundled with an array of onboard functions, the highly-integrated AB49/AB49N
mainboard provides you with a total solution to build the most stable and reli-
able system. Refer to sections 3.2 Jumper Settings and Chapter 4 Drivers/
Software Utilities to find out how to get the best out of your new mainboard.
Chapter 5 BIOS Setup also contains the relevant information on how to tune
up your system to achieve higher performance.
System Integrator
You have wisely chosen Shuttle AB49/AB49N to construct your system.
Shuttle AB49/AB49N incorporates all the state-of-the-art technology of the
845PE (GMCH) chipset from Intel. It integrates the most advanced functions
you can find to date in a compact ATX board.
This manual is all-purpose for two kinds of mainboards: AB49 and
AB49N. The main difference between them is that AB49N is equipped
with an onboard LAN. In the manual, if there are some standards, charac-
teristics, equipment, or software adopted only by AB49N, it will be high-
lighted in brackets.

Step 1
CPU Installation:
This mainboard supports Intel Pentium 4/Celeron Socket 478 series CPU.
Please follow the steps as follows to finish CPU installation.
Note the CPU orientation when you plug it into CPU socket.
1. Pull up the CPU socket lever to 90-degree angle.
2. Locate Pin 1 in the socket and look for a black dot or cut edge on the CPU
upper interface. Match Pin 1 and cut edge, and insert the CPU into the
socket.
3. Press down the CPU socket lever and finish CPU installation.
4. Intel Pentium 4/Celeron processors require a set of heatsink and fan to cool
down the processor. You need to purchase a heatsink and fan if they are not
bundled with your CPU. Required is that install the set and plug its cable
in the CPU fan power connector. Note that there are kinds of CPU fan
connectors. Normally, if your mainboard supports a hardware monitoring
function, a 3-pin fan power connector can have your system detect the
CPU fan's speed. A CPU fan with a 2-pin or 4-pin fan power connector
does not support the detection of the CPU fan's speed, and must directly
be connected to the system's power supply unit.
Note: The CPU might be
damaged if you do not match
the CPU socket Pin 1 and cut
edge well.

Step 2.
Set Jumpers
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:
1. Clear CMOS
2. BIOS Flash Protection
For first-time DIY system builders, we recommend that you do 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 opti-
mum 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 DDR SDRAM System Memory
To install memory, insert DDR SDRAM memory module(s) in any one or two
DIMM banks. Note that 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.

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 de-
scribed 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.

- 15 -
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 the
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 main-
board.

- 16 -
Step 6
Connect Front Panel LEDs/Switches/USB
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,
Green LED, Reset Switch, or a USB device etc.). These cables serve to con-
nect the front-panel LEDs, switches, and a USB connector to the mainboard's
front-panel connectors, PANEL1 and USB3, as shown below.
1. HDD LED (HDLED)
2. Hardware Reset Switch Button
(HWRST)
3. Green LED (GRNLED)
4. ATX Soft Power On/Off (PWRSW)
