Chapter 2: Board Installation
2.1 Installation
Once you’ve checked that everything is inside the box (see p. 4 for details), you will then be ready to
install your motherboard. The mounting hole pattern of the motherboard matches the ATX board specifi-
cations, so your chassis must be capable of supporting an Extended ATX board (check the motherboard
dimensions provided on p. 7).
2.2 How to install our products right.. the first time.
Question: what’s the first thing I should do?
The first thing you should do is read the user’s manual. It contains important information which will make
configuration and setup much easier, as well as provide information on device installation and component
setup. By reading through the manual completely before installing your motherboard, you will have a
complete overview on the installation.
2.3 Here are some safety tips:
(1) Ground yourself properly before removing your motherboard from the antistatic bag. Unplug
the power from your computer power supply and touch any metal part on the computer case. (You
might also want to wear a grounded wrist strap.)
(2) Hold the motherboard by its edges and do not touch the bottom of the board.
(3) Avoid touching motherboard components, IC chips, connectors, and leads.
(4) Avoid touching pins of memory modules and chips.
(5) Place motherboard on a grounded antistatic surface or on the antistatic bag.
Having reviewed the precautions above, the next step is to take the motherboard out of the cardboard box
and static bag, hold it by its edges, and place it on a grounded antistatic surface (such as the bag it came
in), component side up. Then, inspect the board for damage.
Press down on any of the socketed ICs if it appears that they are not properly seated (the board should
still be on an antistatic mat or on top of the bag it came in). Do not touch the bottom of the board. Remem-
ber, don’t take any electronic device out of its protective bag until you are ready to actually start installing
it into the computer case (e.g. setting jumpers, etc.) If you do not ground yourself, you risk zapping the
motherboard or adapter card. Subsequent problems may not arise immediately because electrostatic dis-
charge, unlike physical damage, causes the device to fail over time.
NOTE: DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED!

2.4 Quick References for Jumpers
In this manual, the term “closed” and “on” are used when referring to jumpers (or jumper pins) that are
active; “open” and “off” are used when referring to jumpers (or jumper pins) that are inactive. See Figure
2.0a and Figure 2.0c for examples of “on” and “off” pins and jumpers.
Jumpers and pins are connected by slipping the plastic jumper connector over the top of two adjacent
jumper pins (indicated by 1-2 or 2-3). The metal rod inside the plastic shell bridges the gap between the
two pins, completing the circuit. See Figure 2.0b and Figure 2.0d for more examples of 3-pin jumper
connections. NOTE: The small number “1” indicates pin 1.
The tables and maps on the following pages will help you set the jumpers for CPU speed, infrared, and
external connector pin assignments, among others. The miniature motherboard maps will help you locate
the jumpers on your board. Full page maps of the motherboard can be found on the next two pages.

2.6-I. HDD/SCSI/External LED connector (J12)
This is a 2-pin connector for connecting external LED devices such as SCSI or HDD devices that have
connectors for LED output.
2.6-J. Soft Power Connector
The soft power connector is part of jumper block J15 (pins 6 and 8). This board uses the chipset for power
management, including turning on and off the system. If the power button function option in the BIOS
Power Management menu is set to “On/Off” (which is the default), pressing the power button once after
the BIOS has booted up will turn the system on and off. If the power button function is set to Suspend,
pressing the power button once will wake up the system or send it to Suspend mode. In this case, you
cannot turn the system off unless you shut down through the Windows operating system or you hold the
power button down for four seconds (BIOS-dependent feature).
2.6-K. Hardware Reset Switch Connector Installation
The reset switch on your chassis case provides you with the Hardware Reset function, which is the same
as power on/off, except that the system will immediately execute a cold start after the reset button is
pushed. The reset switch needs to be connected to jumper block J15 (pins 5 and 7).
2.6-L. Flash Utility
You can upgrade the BIOS of this motherboard by using the Flash Utility (see p.47). Check the Tyan web-

2.7 Mounting the Motherboard into the Chassis
Your chassis may include mounting hardware. If mounting hardware was included, you can use the fol-
lowing examples to help you in installing your motherboard into the chassis.
The chassis may have come with the studs integrated into the chassis wall, so in those cases you would
only need to use screws (possibly included with your chassis) to install the motherboard. See the exam-
ples (Figure 2.0, shown below) for more details.
If the chassis includes mounting hardware without the studs pre-installed, then you will need to install the
motherboard using the mounting hardware as shown in the examples below. Remember not to over-
tighten any of the screws, or you might risk breaking internal traces in the surrounding area, or damage
the motherboard in some other way.
Other examples of how to install your motherboard using other hardware (that may or may not have been
included with your chassis) are shown below.

2.8 Installing Memory
Please keep in mind that although some memory modules may appear to be high-quality, they may con-
tain inferior or substandard parts. The type of memory you choose to install should be checked against
the memory compatibility list, which is available from Tyan’s website at http://www.tyan.com
Here are some details of memory installation for this board:
At least one non-registered, unbuffered DIMM must be installed in order to POST.
Supports 128MB, 256MB, 512MB* non-registered, unbuffered DIMMs ONLY.
PC100 supported in a three DIMM setup. PC133 only supported in a two DIMM setup.
The motherboard supports up to 512MB* of PC100/133 SDRAM.
Memory Installation Procedure
Line your module up so that the pins fit into the socket. There is only one way your DIMM can
fit properly. Make sure that the short row of pins is lined up with the short gap in the DIMM
socket, just as the long row of pins should line up with the long gap in the DIMM socket.
Insert the DIMM by pushing the module into the socket with even force. Do not insert one
end and then the other: install the whole module at once or you might bend the DIMM pins.
Make sure the DIMM is securely seated.
* Please check Tyan website for memory compatibility information: http://www.tyan.com

Step
short row of pins long row of pins
2
Step
http://www.tyan.com
18
Lock the DIMM into place by pushing the clips back on either end of the socket onto the
notches in the ends of the DIMM (see pictures below for details).
Removing a DIMM
Removing a DIMM is just the reverse: pull back the clips from the DIMM (see pictures below), and care-
fully pull the module straight out. Place the DIMMs in an anti-static bag as soon as you remove them to
avoid static damage.
Unbuffered and Non-Registered vs. Registered Memory
The 168-pin DIMMs (Dual In-line Memory Modules) must be of the 3.3V PC100/PC133 unbuffered vari-
ety. The notch position in the SDRAM key position will tell you whether or not a DIMM is unbuffered (see
Figure 2.1 below). All installed memory will be auto-detected, so there is no need to set any jumpers.

2.9 Installing the CPU and Cooling Fan
Intel Pentium II processors up to 1.13+GHz and Intel Celerons up to 800MHz can be used on this board.
For more information on CPU compatibility, check Tyan’s website at: http://www.tyan.com.
When installing your CPU, remember the following:
The CPU is a sensitive electronic component and can easily be damaged by static electricity
Do not touch the CPU pins with your fingers
You should be able to insert the CPU into the socket with virtually no force
Do not press down hard on the CPU as you might bend or break pins, or otherwise damage the
CPU
The CPU voltage will automatically be detected by the motherboard, so there is no need to set
any jumpers or BIOS setting.
Installing the CPU
Before installing the CPU, check it for any visible damage. Make sure none of the pins are bent or miss-
ing. Be sure where Pin 1 is on both the CPU and the socket. The following steps each have a correspond-
ing picture next to it to help guide you through the installation.
Carefully lift the arm of the ZIF socket until it is at a 90 degree angle
pointing away from the motherboard. Be very careful not to damage
any components that might be next to the socket.
There are two beveled corners on the CPU, which will match the
two angled corners on the socket. Carefully install the CPU by lining
both Pin 1 on the CPU and Pin 1 on the socket, making sure the
pins actually fit into the socket. Do not force the CPU into the
socket: check the pin alignment of CPU pins to socket holes.
Push down lightly on the CPU while lowering the arm on the socket
to secure the CPU (see right). A squeaking noise may be heard
while lowering the arm, or the socket may make a ‘click’ noise when
the arm is locked into position: these noises are normal.
