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.

2-1. 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
2-4Chapter2
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

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
(2 A ) /(2B ) / (2C): FA N1, FA N2 & FA N3 hea d er
FAN 2
FAN 1
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.
However, differences will exist because of the various brands and types available.
SL6
BIOS Setup3-9
Note
According to Celeron™ PPGA MMX processor types, some Celeron™ PPGA MMX
processors will have the multiplier factor locked and the signal disabled. In this
situation, there is no way to choose a higher multiplier factor.
Speed Error Hold:
✏
The default setting is “Disabled”. If you change the setting to “Enabled” when the
CPU speed setting is wrong, the system will hold.
Normally, we do not recommend that you use the “User Define” option to setup CPU
speed and multiplier factors. This option is for setup of future CPUs whose
specifications are still unknown. The specifications of all present CPUs are included
in the default settings. Unless you are very familiar with all CPU parameters, it is
very easy to make mistakes when you define the external clock and the multiplier
factor by yourself.
Solution in case of booting problem due to invalid clock setup:
Normally, if the CPU clock setup is wrong, you will not be able to boot. In this case, turn the
system off then on again. The CPU will automatically use its standard parameters to boot.
You can then enter the BIOS Setup again and set up the CPU clock. If you can’t enter the
BIOS setup, you must try turning the system on a few times (3~4 times) or press “INSERT”
when turning on, and the system will automatically use its standard parameters to boot. You
can then enter BIOS SETUP again and set up the new parameters.
When you change your CPU:
This motherboard has been designed in such a way that you can turn the system on after
having inserted a CPU in the socket without having to configure any jumpers or DIP
switches. If you change your CPU, normally you just have to turn off the power supply,
change the CPU and then set up the CPU parameters through SOFT MENU
™
II. However,
if the new CPU is slower than the old one (and is the same brand and type), we offer you two
methods to successfully complete the CPU change operation.
Method 1: Setup up the CPU for the lowest speed for its brand. Turn the power supply off
and change the CPU. Then turn the system on again, and set up the CPU
parameters through SOFT MENU
™
II.
Method 2: Since you have to open the computer case when you change the CPU, it could be
a good idea to use the CCMOS jumper to erase the parameters of the original
User’s Manual
3-10Chapter3
CPU and to enter BIOS Setup to set up CPU parameters again.
Attention
After setting up the parameters and leaving the BIOS SETUP, and having verified that
the system can be booted, do not press the Reset button or turn off the power supply.
Otherwise the BIOS will not read correctly, the parameters will fail and you must enter
SOFT MENU™ II again to set up the parameters all over again.
CPU Power Supply:
This option allows you to switch between CPU default and user-defined voltages.
➤➤➤➤CPU Default: The system will detect the CPU type and select the proper voltage
automatically. When it is enabled, the option “Core Voltage” will show
the current voltage setting that is defined by the CPU and this will not be
changeable. We recommend using this CPU default setting and not
changing it unless the current CPU type and voltage setting can not be
detected or is not correct.
➤➤➤➤User Define: This option lets the user select the voltage manually. You can change
values of the “Core Voltage” option lists by using the Page Up and Page
Down keys.
Spread Spectrum:
Two options are available: Disabled ) Enabled. The default setting is Disabled. For EMC
(Electro-Magnetic Compatibility) testing, you may need to adjust these options for optimal
results. We do not recommend you change the default, except for special reasons. Some
values you select may cause system instability under some situations. Please be careful.

IDE HDD Auto-Detection:
Press the Enter key for the BIOS to auto detect all detailed parameters of the hard disk
drivers (HDD). If auto detection is successful, the correct values will be shown in the
remaining items of this menu.
Note
* A new IDE HDD must be first formatted, otherwise it can not read/write. The basic
step in using a HDD is to make a HDD low-level format, then run FDISK, and then
FORMAT the drive. Most current HDDs have already been subjected to low-level
format at the factory, so you can probably skip this operation. Remember though, the
primary IDE HDD must have its partition set to active within the FDISK procedure.
+ If you are using an old HDD that is already formatted, auto detection can not detect
the correct parameters. You may need to do a low-level format or set the parameters
manually, and then check if the HDD is working.
SL6
BIOS Setup3-13
IDE Primary Master:
Three settings are available: Auto, Manual and None. If you choose Auto, the BIOS will
automatically check what kind of hard disk you are using. If you want to set the HDD
parameters yourself, make sure you fully understand the meaning of the parameters, and be
sure to refer to the manual provided by the HDD manufacture to get the settings right.
Access Mode:
Since old operating systems were only able to support HDDs with capacities no bigger than
528MB, any hard disk with more than 528MB was unusable. AWARD BIOS features a
solution to this problem: you can, according to your operating system, choose four operating
modes: NORMAL ) LBA ) LARGE )Auto.
The HDD auto detection option in the sub-menu will automatically detect the parameters of
your hard disk and the mode supported.
➤➤➤➤ Auto:
Lets the BIOS detect your HDD access mode and make the decisions.
➤➤➤➤ Normal mode:
Standard normal mode supports hard disks of up to 528MB or less. This mode directly
uses positions indicated by Cylinders (CYLS), Heads, and Sectors to access data.
➤➤➤➤ LBA (Logical Block Addressing) mode:
The earlier LBA mode can support HDD capacities of up to 8.4GB, and this mode uses a
different method to calculate the position of disk data to be accessed. It translates
Cylinders (CYLS), Heads and Sectors into a logical address where data is located. The
Cylinders, Heads, and Sectors displayed in this menu do not reflect the actual structure
of the hard disk. They are just reference values used to calculate actual positions.
Currently, all high capacity hard disks support this mode and that is why we recommend
you use this mode. Currently, the BIOS can support the INT 13h extension function,
enabling the LBA mode to support hard disk drive capacities exceeding 8.4GB.
➤➤➤➤ Large Mode:
When the number of cylinders (CYLs) of the hard disk exceeds 1024 and DOS is not
able to support it, or if your operating system does not support LBA mode, you should
select this mode.
Capacity:
This item auto displays your HDD size. Note that this size is usually slightly greater than the

size given by a disk checking program of a formatted disk.
Note
All the items below are available when you set the item Primary IDE Master to Manual.
Cylinder:
When disks are placed directly above one another along the shaft, the circular vertical
"slice" consisting of all the tracks located in a particular position is called a cylinder. You
can set the number of cylinders for a HDD. The minimum number you can enter is 0, the
maximum number you can enter is 65536.
Head:
This is the tiny electromagnetic coil and metal pole used to create and read back the
magnetic patterns on the disk (also called the read/write head). You can configure the
number of read/write heads. The minimum number you can enter is 0, the maximum number
you can enter is 255.
Precomp:
The minimum number you can enter is 0, the maximum number you can enter is 65536.
War ni ng
Setting a value of 65536 means no hard disk exists.
Landing Zone:
This is a non-data area on the disk's inner cylinder where the heads can rest when the power
is turned off. The minimum number you can enter is 0, the maximum number you can enter
is 65536.
Sector:
The minimum segment of track length that can be assigned to stored data. Sectors usually
are grouped into blocks or logical blocks that function as the smallest units of data permit.

Virus Warning:
This item can be set to Enabled or Disabled, the default setting being Disabled.
When this feature is enabled, if there is any attempt from a software or an application to
access the boot sector or the partition table, the BIOS will warn you that a boot virus is
attempting to access the hard disk.
CPU Level 1 Cache:
This item is used to enable or to disable the CPU level 1 cache. When the cache is set to
Disabled it is much slower, so the default setting for this item is Enabled since it will speed
up memory access. Some old and very poorly written programs will make the computer
malfunction or crash if the system speed is too high. In this case, you should disable this
feature. The default setting is Enabled.
CPU Level 2 Cache:
This item is used to enable or to disable the CPU level 2 cache. When the external cache is
enabled, it will speed up memory access, and the system will work faster. The default setting
is Enabled.

Third Boot Device:
Description is same as the First Boot Device, the default setting is LS/ZIP
Boot Other Device:
Two options are available: Enabled or Disabled. The default setting is Enabled. This setting
allows the BIOS to try three kinds of boot devices that are set from the above three items.
Swap Floppy Drive:
This item can be set as Enabled or Disabled. The default setting is Disabled. When this
feature is enabled, you don’t need to open the computer case to swap the position of floppy
disk drive connectors. Drive A can be set as drive B and drive B can be set as drive A.
Boot Up Floppy Seek:
When the computer boots up, the BIOS detects if the system has an FDD or not. When this
item is enabled, if the BIOS detects no floppy drive, it will display a floppy disk drive error
message. If this item is disabled, the BIOS will skip this test. The default setting is Disabled.

3-4. Advanced Chipset Features Setup Menu
The Chipset Features Setup Menu is used to modify the contents of the buffers in the chipset
on the motherboard. Since the parameters of the buffers are closely related to hardware, if
the setup is not correct or is false, the motherboard will become unstable or you will not be
able to boot up. If you don’t know the hardware very well, use default values (i.e. use the
LOAD SETUP DEFAULTS option). The only time you might consider making any
changes is if you discover that data is being lost while using your system.

3-6. Power Management Setup Menu
The difference between Green PCs and traditional computers is that Green PCs have a
power management feature. With this feature, when the computer is powered on but inactive,
the power consumption is reduced in order to save energy. When the computer operates
normally, it is in Normal mode. In this mode, the Power Management Program will control
the access to video, parallel ports, serial ports and drives, and the operating status of the
keyboard, mouse and other device. These are referred to as Power Management Events. In
cases where none of these events occur, the system enters the power saving mode. When one
of the controlled events occurs, the system immediately returns to normal mode and
operates at its maximum speed. Power saving modes can be divided into three modes
according to their power consumption: Doze Mode, Standby Mode, and Suspend Mode. The
The system consumption is reduced according the following sequence:
Normal>Doze >Standby>Suspend
1. In the Main Menu, select "Power Management Setup" and press "Enter". The following
screen is displayed:

ACPI Function (Advanced Configuration and Power Interface):
ACPI gives the operating system direct control over the power management and Plug and
Play functions of a computer.
User’s Manual
3-34Chapter3
There are two options that can be selected, “Enabled” and “Disabled”. You can select
“Enabled” to enable ACPI functions. If you want ACPI functions to work normally, you
should notice two things. One is your operating system must support ACPI, as of now only
Microsoft
®
Windows® 98 supports these functions. The second thing is that all devices and
add-on cards in your system must fully support ACPI, both hardware and software (drivers).
If you want to know if your devices or add-on cards support ACPI or not, please contact the
device or add-on card manufacture for more information. If you want to know more about
ACPI specifications, please go to the address below for more detailed information:
http://www.teleport.com/~acpi/acpihtml/home.htm
Note: If you enable the ACPI function in the BIOS setup, the SMI function will not work.
ACPI requires an ACPI-aware operating system. ACPI features include:
! Plug and Play (including bus and device enumeration) and APM functionality normally
contained in the BIOS.
! Power management control of individual devices, add-in cards (some add-in cards may
require an ACPI-aware driver), video displays, and hard disk drives.
! A Soft-off feature that enables the operating system to power off the computer.
! Support for multiple wake-up events (see Table 3-6-1).
! Support for a front panel power and sleep mode switch. Table 3-6-2 describes the system
states based on how long the power switch is pressed, depending on how ACPI is
configured with an ACPI-aware operating system.
Note
If you enable the ACPI function in the BIOS setup, the SMI switch function will not
work.
System States and Power States
Under ACPI, the operating system directs all system and device power state transitions. The
operating system puts devices in and out of low-power states based on user preferences and
knowledge of how devices are being used by applications. Devices that are not being used
can be turned off. The operating system uses information from applications and user settings
to put the system as a whole into a low-power state.
Table 3-6-1: Wake Up Device and Events
The table below describes which devices or specific events can wake the computer from
specific states.

ACPI Suspend Type:
Two options are available: S1(POS) and S3(STR). The default setting is S1(POS). Generally,
ACPI has six states: System S0 state, S1, S2, S3, S4, S5. S1 and S3 states are described
below:
The S1 (POS) State (POS means Power On Suspend):
While the system is in the S1 sleeping state, its behavior is as described below:
! The processor is not executing instructions. The processor’s complex context is
maintained.
! Dynamic RAM context is maintained.
! Power Resources are in a state compatible with the system S1 state. All Power Resources
that supply a System Level reference of S0 are in the OFF state.
! Devices states are compatible with the current Power Resource states. Only devices
which solely reference Power Resources which are in the ON state for a given device state
can be in that device state. In all other cases, the device is in the D3 (off) state.
! Devices that are enabled to wake the system and that can do so from their current device
state can initiate a hardware event which transitions the system state to S0. This transition
causes the processor to continue execution where it left off.
……and the power switch
is pressed for……the system enters this
state
User’s Manual
3-36Chapter3
To transition into the S1 state, the operating software does not have to flush the processor's
cache.
The S3 (STR) State (STR means Suspend to RAM):
The S3 state is logically lower then the S2 state and is assumed to conserve more power. The
behavior of this state is defined as follows:
! Processor is not executing instructions. The processor complex context is not maintained.
! Dynamic RAM context is maintained.
! Power Resources are in a state compatible with the system S3 state. All Power Resources
that supply a System Level reference of S0, S1, or S2 are in the OFF state.
! Devices states are compatible with the current Power Resource states. Only devices
which solely reference Power Resources which are in the ON state for a given device state
can be in that device state. In all other cases, the device is in the D3 (off) state.
! Devices that are enabled to wake the system and that can do so from their current device
state can initiate a hardware event which transitions the system state to S0. This transition
causes the processor to begin execution at its boot location. The BIOS performs
initialization of core functions as required to exit an S3 state and passes control to the
firmware resume vector. Please see the ACPI Specification Rev. 1.0 book section 9.3.2
for more details on BIOS initialization.
From the software point of view, this state is functionally the same as the S2 state. The
operational difference can be that some Power Resources that could be left ON in the S2
state might not be available to the S3 state. As such, additional devices can be required to be
in logically lower D0, D1, D2, or D3 state for S3 than S2. Similarly, some device wake
events can function in S2 but not S3.
Because the processor context can be lost while in the S3 state, the transition to the S3 state
requires that the operating software flush all dirty cache to DRAM.
Above information for system S0 & S3 were refer to ACPI Specification Rev. 1.0.
