User Friendly Instructions
Our objective is to enable the novice computer user to perform the installation by him or
herself. We have attempted to write this document in a very clear, concise and descriptive
manner to help overcome any obstacles you may face during installation. Please read our
instructions carefully and follow them step-by-step.

2-2 Chapter2
SL6
2-1. Installing the Motherboard to the Chassis
Most computer chassis will have a base on which there will be many mounting holes that
allows the motherboard to be securely attached and at the same time, prevents short circuits.
There are two ways to attach the motherboard to the base of chassis:
!with studs
!or with spacers
Please refer to figure 2-1, which shows the studs and spacers. There may be several types,
but all look similar to the figures below:
In principle, the best way to attach the
motherboard is with studs. Only if
you are unable to do this should you
attach the board with spacers. Take a
careful look at the motherboard and
you will see many mounting holes on
it. Line these holes up with the
mounting holes on the base. If the
holes line up and there are screw holes
this means you can attach the motherboard with studs. If the holes line up and there are only
slots, this means you can only attach the motherboard with spacers. Take the tip of the
spacers and insert them into the slots. After doing this to all the slots, you can slide the
motherboard into position aligned with the slots. After the motherboard has been positioned,
check to make sure everything is OK before putting the casing back on.
Figure 2-2 shows you the way to affix the motherboard using studs or spacers:

Installing the Motherboard 2-3
User’s Manual
Note
If the motherboard has mounting holes, but they don’t line up with the holes on the base
and there are no slots to attach the spacers, do not despair, you can still attach the
spacers to the mounting holes. Just cut the bottom portion of the spacers (the spacers
may be a little hard to cut , so mind your fingers). In this way, you can still attach the
motherboard to the base without worrying about short circuits. Sometimes you may
need to use the plastic springs to isolate the screw from the motherboard PCB surface as
the circuit wire may be too near the hole. Be careful. Do not let the screw contact the
printed circuit wire or parts on the PCB that are near the fixing hole. Otherwise it may
damage the board or cause board malfunctioning.
2-2. Installation of the Pentium


III CPU
The installation method for the CPU is printed on the package of the retention mechanism
that comes with the motherboard. You can refer to it while you install the CPU.
Note:
!Installing a heat sink and cooling fan is necessary for proper heat dissipation from
your CPU. Failing to install these items may result in overheating and damage of
your CPU.
!Please refer to your boxed processor installation or other documentation attached
with your CPU for detailed installing instructions.

2-3. Installing System Memory
This motherboard provides three 168-pin DIMM sites for memory expansion. The DIMM
sockets support 8Mx64 (64MB), 16Mx64 (128MB), 32Mx64 and (256MB) DIMM
modules. Minimum memory size is 64MB and maximum memory size is 512MB SDRAM.
In order to create a memory array, certain rules must be followed. The following set of rules
allows for optimum configurations.
!The memory array is 64 or 72 bits wide. (depending on with or without parity)
!Those modules can be populated in any order.
!Supports single and double density DIMMS.
Table 2-1. Valid Memory Configurations

Generally, installing SDRAM modules to your motherboard is an easy thing to do. You can
refer to figure 2-3 to see what a 168-pin PC100 & PC133 SDRAM module looks like.
DIMMs may be "snapped" directly into
the socket. Note: Certain DIMM sockets
have minor physical differences. If your
module doesn't seem to fit, please do not
force it into the socket as you may
damaged your memory module or
DIMM socket.
The following procedure will show you how to install a DIMM module into a DIMM socket.
Step 1. Before you install the memory module, please place the computer power switch in
the off position and disconnect the AC power cord.
Step 2. Remove the computer’s chassis cover.
Figure 2-3 PC100/PC133/VCM Module and
Component Mark

Installing the Motherboard 2-5
User’s Manual
Step 3. Before touching any electronic
components, make sure you first touch
an unpainted, grounded metal object to
discharge any static electricity stored on
your clothing or body.
Step 4. Locate your computer’s 168-pin
memory expansion DIMM socket.
Step 5. Insert the DIMM module into
the expansion socket as shown in the
illustration. Note how the module is
keyed to the socket. You can refer to
figure 2-4 for the details. This insures the DIMM module will be plugged into the
socket in one way only. Firmly press the DIMM module into the DIMM socket,
making certain the module is completely seated in the DIMM socket.
Step 6. Once the DIMM module has been installed, the installation is complete and the
computer’s cover can be replaced. Or you can continue to install other devices and
add-on cards that are mentioned in the following section.
Note
When you install a DIMM module fully into the DIMM socket, the eject tab should be
locked into the DIMM module very firmly and fit into its indention on both sides.
It is difficult to differentiate between the PC100, PC133 SDRAM and VCM DRAM
modules from the exterior. The only way to identify them is through the sticker on the RAM
module.

2-4. Connectors, Headers and Switches
Inside the case of any computer several cables and plugs have to be connected. These cables
and plugs are usually connected one-by-one to connectors located on the motherboard. You
need to carefully pay attention to any connection orientation the cables may have and, if any,
notice the position of the first pin of the connector. In the explanations that follow, we will
describe the significance of the first pin.
We will show you all of the connectors, headers and switches here, and tell you how to
connect them. Please pay attention and read the entire section for necessary information
before attempting to finish all of the hardware installation inside the computer chassis.
Figure 2-5 shows you all of the connectors and headers that we’ll discuss in the next section,
you can use this diagram to visually locate each connector and header we describe.
All connectors, headers and switches mentioned here will depend upon your system
configuration. Some features you may (or may not) have and need to connect or configure
depending on the peripheral. If your system doesn't have such add-on cards or switches you
can ignore some special feature connectors.

First, Let’s look at the headers that the SL6 uses, and what their functions are.
(1) ATXPWR1: ATX Power Input Connector
Caution
If the power supply connectors are not properly attached to the ATXPR1 power supply,
the power supply or add-on cards may be damaged.
Attach the connector from the power supply
to the ATXPR1 connector here. Remember
you have to push the connector from the
ATX power supply firmly into the ATXPR1
connector, ensuring that you have a good
connection.
Note: Watch the pin position and the
orientation
(2A)/(2B)/(2C): FAN1, FAN2 & FAN3 header
Attach the connector from the individual
CPU fan to the header named FAN1. The
connector from the chassis fan should be
attached to the header FAN3 and the
connector from the power fan to FAN2.
You must attach the CPU fan to the
processor or your processor will work
abnormally or may be damaged by
overheating. To keep the computer’s
internal temperature steady and not too high,
connecting the chassis fan is imperative.
Note: Watch the pin position and the orientation

IR1
WOL1
(3) IR1: IR Header (Infrared)
There is a specific orientation for pins 1
through 5, attach the connector from the IR
KIT or IR device to the IR1 header (left row
only). This motherboard supports standard
IR transfer rates.
Note: Watch the pin position and the
orientation
(4) WOL1: Wake on LAN Header
If you have a network adapter that supports
this feature, then you can connect the
specific cable from the network adapter to
this header. This feature lets you wake up
your computer via remote control through a
local area network. You may need a specific
utility to control the wake up event, such as
the PCnet Magic Packet utility or other
similar utilities.
Note: Watch the pin position and the orientation

User’s Manual
SMB1
RT2
CD1
(5) SMB1: System Management Bus Connector
This connector is reserved for system
management bus (SM bus). The SM bus is a
specific implementation of an I2C bus. I2C is
a multi-master bus, which means that
multiple chips can be connected to the same
bus and each one can act as a master by
initiating a data transfer. If more than one
master simultaneously tries to control the
bus, an arbitration procedure decides which
master gets priority.
Note: Watch the pin position and the orientation
(6) RT2 Thermister:
The RT2 is a thermistor used to detect the
system environmental temperature. It may
also be called a system temperature detector.
You can attach one end of the two-threaded
thermal cable that comes with the
motherboard to the RT2 header, then tape
the other end of the thermal cable on the
CPU’s heat sink. Generally speaking, the
location you tape the thermistor should be as
near the CPU chipset as possible and avoid having it near the CPU fan.
(7) CDIN1: Internal CD-ROM Drive Audio Cable Header
This header is for the internal CD-ROM
drive audio cable connection. Please check
your audio cable attached with the CD-
ROM drive to see which type of connector
you have and then plug it into this header.
