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.

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.

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.
This fits into the matching slot on the mating
plugs on the motherboard and the drives,
Figure 2-10. How to connect an ATA/66
Cable to the Motherboard
& The red line on the cable should be aligned with pin #1. On the drives this will result in the
red line facing the power connector. Attach the BLUE connector to the appropriate 40 pin
IDE plug on the motherboard.
thus assuring positive mating (pin #1 to pin
#1)

BIOS Setup 3-1
Chapter 3. Introducing the BIOS
The BIOS is a program located on a Flash Memory chip on the motherboard. This program
will not be lost when you turn the computer off. This program is also referred to as the boot
program. It is the only channel the hardware circuit has to communicate with the operating
system. Its main function is to manage the setup of the motherboard and interface card
parameters, including simple parameters such as time, date, hard disk drive, as well as more
complex parameters such as hardware synchronization, device operating mode, CPU SOFT
MENU™ II features and setup of CPU speed. The computer will operate normally, or will
operate at its best, only if all of these parameters are correctly configured through the BIOS.
Don’t change the parameters inside the BIOS unless you fully understand
''''
their meanings and consequences
The parameters inside the BIOS are used to setup the hardware synchronization or the
device-operating mode. If the parameters are not correct, they will produce errors, the
computer will crash, and sometimes you will not even be able to boot the computer after
it has crashed. We recommend that you do not change the parameters inside the BIOS
unless you are very familiar with them. If you are not able to boot your computer
anymore, please refer to the section “Erase CMOS data” in Chapter 2.
When you start the computer, the BIOS program controls it. The BIOS first operates an
auto-diagnostic test called POST (Power On Self Test) for all of the necessary hardware. It
then configures the parameters of the hardware synchronization, and detects all of the
hardware. Only when these tasks are completed does it give up control of the computer to
the next level, which is the operating system (OS). Since the BIOS is the only channel for
hardware and software to communicate, it is the key factor for system stability, and in
ensuring that your system performs at its best. After the BIOS has achieved the auto-
diagnostic and auto-detection operations, it will display the following message:
PRESS DEL TO ENTER SETUP
The message will be displayed for three to five seconds, if you press the Del key, you will
access the BIOS Setup menu. At that moment, the BIOS will display the following message:

Computer Knowledge: CMOS Data
Maybe you have heard somebody saying that his or her CMOS DATA was lost. What is
the CMOS? Is it important? The CMOS is the memory used to store the BIOS
parameters that you have configured. This memory is passive. You can read its data, and
you can also store data in it. But this memory has to be powered by a battery in order to
avoid any loss of its data when the computer is turned off. Since you may have to
change the CMOS battery when it is out of power, and if doing so you will lose all
CMOS data, we recommend that you write down all the parameters of your hardware,
or to put a label with these parameters on your hard disk.

The wrong settings of the multiplier and external clock in certain circumstances may
cause CPU damage. Setting the working frequency higher than the PCI chipset or
processor specs, may cause abnormal memory module functioning, system hangs, hard
disk drive data lose, abnormal functioning of the VGA card, or abnormal functioning
with other add-on cards. Using non-specification settings for your CPU is not the
intention of this explanation. These should be used for engineering testing, not for
normal applications.
If you use non-specification settings for normal operation, your system may not be
stable, and may effect system reliability. Also, we do not guarantee the stability and
compatibility for settings that are not within specification, and any damage of any
elements on the motherboard or peripherals, is not our responsibility.

How is each component’s working frequency calculated? For starters, everything is
derived from the clock generator on the motherboard. Upon boot up the CPU will
give the clock generator the default value for the Front Side Bus (FSB). Once the
User’s Manual
3-6 Chapter3
FSB has been set, all of the other components will be able derive their proper
operating frequencies.
For example: If you have a CPU rated for a 100MHz FSB, the operating frequencies
for the proper values for the FSB : SDRAM : PCI for your CPU would be
calculated thusly:
Pentium III
100MHz (3:3:1) (each divided by 3) (FSB) 100MHz : (SDRAM) 100MHz : (PCI)
33MHz
CPU FSB value = 100MHz x 1 = 100MHz (proper FSB value for this CPU)
SDRAM value = FSB 100MHz x 1 = 100MHz (proper value for PC100 RAM)
PCI value = FSB 100MHz x 1/3 = 33MHz (proper value for PCI bus)
So that for this example above you can see that the x1, x1, x 1/3 values in
relation to the FSB can be written as
Additionally, for the working value of the CPU (in this case a Pentium® III 500MHz
you calculate it like this:
CPU working value = FSB 100MHz x 5 = 500MHz (proper value for this CPU)
Also, the AGP value is derived from the PCI value so that:
®
CPU with 100MHz FSB running at 500MHz:
100MHz (1: 1: 1/3)
AGP value = PCI value (33MHz) x 2 or (4) = 66MHz or (132MHz) (proper
value for AGP bus) For a 2x AGP it works at double the speed of the PCI bus,
and four times for 4x AGP.
When the FSB is above 100MHz, such as 133MHz, you can choose a PCI divider of
4, again giving you the proper 33MHz value.
Now, in the BIOS they do not write dividers in fractions but rather in whole integers,
so that again for the 100MHz FSB example,
above it looks like this:
100MHz (3:3:1)
But you need to remember that each value is also divided by 3
you can look at it as if it were:
100MHz (3:3:1) each divided by 3
but you can also look at it as if it were:
SL6
100MHz (1: 1: 1/3)
,
in the table
BIOS Setup 3-7
100MHz (1: 1: 1/3) each multiplied times 3 then (divided by 3)
or
100MHz (3/3: 3/3: 1/3) each multiplied times 3 then (divided by 3)
which both equal:
100MHz (3:3:1)
Now the final point about this table is that it does not show the necessary divider, i.e.
for the 100MHz (3:3:1) example you still need to divide each by 3, even though it
does not show that in the table.
Accordingly, for the 66MHz (2:3:1) you will divide each by 2 and for the 138MHz
(4:3:1) example you would divide each by 4. The first value in the parenthesis is the
value for the CPU’s FSB, and because everything derives its working frequency
from the FSB, that value must always equal 1. So for (3:3:1) you need to divide by 3,
for (2:3:1) you need to divide by 2 and for (4:3:1) you need to divide by 4.
So for the 100MHz (3:3:1) example in the table above, to get the working values you
are taking the (3:3:1) numbers and multiplying by 3 then dividing by 3.
For another example, in the table you have 138MHz (4:3:1) (divided by 4). You can
look at it like this: 138MHz (1: 3/4: 1/4). Each multiplied times 4 will give you the
same value as 138MHz (4:3:1). (needing to be divided by 4 again). So that for the
FSB you have 4 divided by 4 giving you a value of 1, so that 138MHz will come out
to 138MHz.
CPU FSB value =138MHz x1=138MHz (approximate proper FSB value for this
CPU)
SDRAM value = FSB 138MHz x 3/4 = 103.5MHz (approximate proper value
for PC100 RAM)
PCI value = FSB 138MHz x 1/4 = 34.5MHz (approximate proper value for PCI
bus)
(divided by 3)
Giving you all the proper values
(within a few MHz or so, its
never exactly precise)
Another way to look at it would be that for the 138MHz (4:3:1) example, you could
use this “maximum number” value of 4, and then you could divide FSB value of
138MHz by 4 which equals 34.5MHz. You could then use 34.5MHz as the base
number to be multiplied by the number for the components. So that:
User’s Manual
3-8 Chapter3
CPU FSB frequency will be 34.5MHz x 4 =138MHz.
The SDRAM working frequency will be 34.5MHz x 3 =103.5MHz.
And the PCI bus working frequency will be 34.5MHz x 1 = 34.5MHz.
Giving you all the proper values
(within a few MHz or so, its
never exactly precise.)
ABIT patented technology, SoftMenu™ allows you to adjust the FSB working
frequency, when you adjust the working frequency, please choose the proper values
for the FSB : SDRAM : PCI for your CPU. For example:
A CPU rated for 66MHz FSB ( such as Celeron
66MHz (2:3:1) (each divided by 2): 66MHz : 100MHz : 33MHz
or a CPU rated for 100MHz FSB (such as Pentium
PGA)
100MHz (3:3:1) (each divided by 3) 100MHz : 100MHz : 33MHz
or a CPU rated for 133MHz FSB (such as a Pentium
FC-PGA)
133MHz (4:3:1) (each divided by 4) 133MHz : 100MHz : 33MHz
Note: the various components and their corresponding “bus speeds” should still
work fine, nonetheless going too far “out of spec” may cause system damage
or malfunction. System performance will depend mainly on the quality of the
components used.
Note
CPU bus speed above 66MHz/100MHz/133MHz supported but not guaranteed due to
the PCI and chipset specs.

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
3-10 Chapter3
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.

* 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.

Access Mode:
Since old operating systems were only able to support HDDs with capacities no bigger than

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.

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
four modes proceed in the following sequence:
Normal Mode ===> Doze Mode ===> Standby Mode ===> Suspend Mode
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
3-34 Chapter3
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
3-36 Chapter3
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.

When one of the specified events occur, the count down made for entry in power saving
mode goes back to zero. Since the computer will enter a power saving mode only after an
inactivity delay specified (time specific for Doze, Standby and Suspend modes) and after it
has no activity, during this time period, any event will cause the computer to re-count the
time elapsed. Resume events are operations or signals that cause the computer to resume
time counting.

3-7. PnP/PCI Configurations
This section describes configuring the PCI bus system. PCI, or Personal Computer
Interconnect, is a system which allows I/O devices to operate at speeds nearing the speed the
CPU itself uses when communicating with its own special components. This section covers
some very technical items and it is strongly recommended that only experienced users
should make any changes to the default settings.
Figure 3-11. PnP/PCI Configurations Setup Screen Shot
PNP OS Installed:
Two options are available: No and Yes. Default setting is No. Device resource assigned by
PnP OS or BIOS.
Force Update ESCD:
If you want to clear ESCD data next time you boot up, and ask the BIOS to reset the settings
for the Plug & Play ISA Card and the PCI Card, select Enabled. But the next time you boot
up, this option will automatically be set as Disabled.
User’s Manual
3-42 Chapter3
Computer Knowledge: ESCD (Extended System Configuration Data)
The ESCD contains the IRQ, DMA, I/O port, memory information of the system. This
is a specification and a feature specific to the Plug & Play BIOS.
Resources Controlled By:
Two options are available: Auto(ESCD) and Manual. Default setting is Auto(ESCD). When
the setting is Auto(ESCD), the IRQ Resources and Memory Resources can not be changed.
When resources are controlled manually, the IRQ Resources and Memory Resources can
then be changed.
Legacy ISA devices compliant with the original PC AT bus specification, requiring a specific
interrupt (such as IRQ4 for serial port 1).
PCI/ISA PnP devices compliant with the Plug and Play standard, whether designed for the
PCI or ISA bus architecture.
The Award Plug and Play BIOS has the capability to automatically configure all of the boot
and Plug and Play compatible devices. If you select Auto (ESCD), The IRQ Resources item
will be disabled, as the BIOS automatically assigns them. But if you have trouble in
assigning the interrupt resources automatically, you can select Manual to set which IRQ and
DMA are assigned to PCI/ISA PnP or legacy ISA cards.
Figure 3-12 shows you the screen of IRQ resources. Each item has two options: PCI Device
and Reserved. The default setting is PCI Device.
PCI /VGA Palette Snoop:
This option allows the BIOS to preview VGA Status, and to modify the information
delivered from the Feature Connector of the VGA card to the MPEG Card. This option can
solve the display inversion to black after you have used the MPEG card.
PIRQ_0~PIRQ3:
Eleven options are available: Auto, 3, 4, 5, 7, 9, 10, 11, 12, 14, 15. Default setting is Auto.
This item allows the system to automatically specify the IRQ number for the device installed
on PCI slots. Which means, the system can specify the fixed IRQ number for the device
installed on the PCI slots (PCI slot 1 to PCI slot 5). This is a useful function when you want
to fix the IRQ for a specific device.
SL6
BIOS Setup 3-43
For example, if you want to move your hard disk to another computer and don’t want to
re-install Windows
®
NT, then you can specify the IRQ for the device installed on the new
computer to fit the original computer settings.
Note
If you specify the IRQ in this item, then you cannot specify the same IRQ to the ISA
bus, otherwise, it will cause a hardware conflict.
This feature is for the operating system which will record and fix the PCI configuration
status, if you want to change it.
For the relations between the hardware layout of PIRQ (the signals from the 810E chipset),
INT# (means PCI slot IRQ signals) and devices, please refer to the table below:

PCI slot 2
PCI slot 3 PCI slot 4
PCI slot 5 PIRQ_0 INT A INT B INT C INT D PIRQ_1 INT B INT C INT D INT A PIRQ_2 INT C INT D INT A INT B PIRQ_3 INT D INT A INT B INT C
! Each PCI slot has four INT#s (INT A~INT D).
