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.
User’s Manual
2-2 Chapter2
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:
SL6
Installing the Motherboard 2-3
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.
User’s Manual
2-4 Chapter2
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.

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

DIMM socket.
Installing the Motherboard 2-5
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
Figure 2-4. Memory module installation
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.
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.

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.
SL6
Figure 2-5. All Connectors and Headers for the SL6
Installing the Motherboard 2-7
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
ATXP R1

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
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

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
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
SL6
Installing the Motherboard 2-9
(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 I
2
C 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
SMB1
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.
RT2
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
CD1
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.

Let’s now see the I/O connectors that the SL6 uses, and what their functions are.
(11) FDC1 Connector
PN2
PIN 14 No connection
This 34-pin connector is called the “floppy
disk drive connector”. You can connect a
360K, 5.25”, 1.2M, 5.25”, 720K, 3.5’’,
1.44M, 3.5” or 2.88M, 3.5” floppy disk
drive. You can even connect a 3 Mode
floppy disk drive (a 3 1/2” drive used in
Japanese computer systems).
A floppy disk drive ribbon cable has 34
wires and two connectors to provide the
connection of two floppy disk drives. After
connecting the single end to the FDC1, connect the two connectors on the other end to the
floppy disk drives. In general, people only install one floppy disk drive on their computer
system. The end attached to the longer length of ribbon should be attached to the
motherboard connector.
User’s Manual
2-14 Chapter2
Note
A red mark on a wire typically designates the location of pin 1. You need to align pin 1
of the wire to pin 1 of the FDC1 connector and then insert.
(12) IDE1 and IDE2 Connectors
An IDE hard disk drive ribbon cable has 40
wires and two connectors to provide a
connection for two IDE hard disk drives.
After connecting the single end to the IDE1
(or IDE2), connect the two connectors on
the other end to the IDE hard disk drives (or
CD-ROM drive, LS-120, etc.). Again the
connector attached to the longer ribbon
length should be attached to the mobo.
Before you install a hard disk, there are
some things you need to be aware of:
“Primary” refers to the first connector on the motherboard; that is, the IDE1 connector on
♦
the motherboard.
“Secondary” refers to the second connector on the motherboard; that is, the IDE2
♦
connector on the motherboard.
Two hard disks can be connected to each connector:
♦
The first HDD is referred to as the “Master” and the second HDD is referred to as the
“Slave”.
For performance issues, we strongly suggest you don’t install a CD-ROM drive on the
♦
same IDE channel as a hard disk. Otherwise, the system performance on this channel may
drop. (how much depends on your CD-ROM drive performance)
Note
!The Master or Slave status of the hard disk drive is set on the hard disk itself. Please
refer to the hard disk drive user’s manual.
!A red mark on a wire typically designates the location of pin 1. You need to align the
wire pin 1 to the FDC1 connector pin 1, then insert the wire connector into the FDC1
connector.
SL6
Installing the Motherboard 2-15
The SL6 supports the Ultra ATA/66 (Also known as Ultra DMA/66) specification. It
enhances existing Ultra ATA/33 technology by increasing both performance and data
integrity. This new high-speed interface doubles the Ultra ATA/33 burst data transfer rate to
66.6 Mbytes/sec. The result is maximum disc performance using the current PCI local bus
environment. Figure 2-8 shows you the different between the Ultra ATA/33 and Ultra
ATA/66 Conductor Cable.
Figure 2-8. The difference between Ultra ATA/33 and Ultra ATA/66 Conductor Cables
Figure 2-9 shows you a photo of an Ultra ATA/66 Conductor Cable. An Ultra ATA/66-
capable cable is a 40-pin, 80-conductor cable with a black connector on one end, a blue
connector on the other end and a gray connector in the middle. In addition, line 34 on the
cable should be notched or cut (this may be difficult to see).
Ultra ATA/66 is backwards compatible with all Ultra ATA/33 systems, but it will be limited
in its transfer mode to the Ultra ATA/33 (Ultra DMA Mode 2 - 33 Mbytes/sec) or PIO Mode
4 (16.6 Mbytes/sec). Ultra ATA/66 hard drives are 100 percent backward compatible with
both Ultra ATA/33 and DMA and with existing ATA
(IDE) hard drives, CD-ROM drives, and host systems.
The Ultra ATA/66 protocol and commands are designed
to be compatible with existing ATA (IDE) devices and
systems. Although a new 40-pin, 80-conductor cable is
required for Ultra ATA/66, the chip set pin connector
remains the same at 40. Hard drives that support Ultra
ATA/66 also support Ultra ATA/33 and legacy ATA (IDE)
specifications.
There are four requirements for attaining Ultra ATA/66:
*The drive must support Ultra ATA/66.
Figure 2-9. Photo of an Ultra
ATA/66 Conductor Cable
*The motherboard and system BIOS (or an add-in
controller) must support Ultra ATA/66.
User’s Manual
2-16 Chapter2
*The operating system must support Direct Memory Access (DMA); Microsoft Windows
98 and Windows 95B (OSR2) support DMA.
*The cable must be an 80-pin conductor. The length should not exceed 18 inches. If all of
the above requirements are met, you can enjoy the Ultra ATA/66 features of your computer
system.
How to install the Ultra ATA/66 Cable Assembly:
& The BLUE connector MUST be plugged
into the motherboard or your system will not
work.
& Each connector on the Ultra ATA/66
cable assembly has a small polarization tab
centrally located on the body of the plastic.
