Chapter 1. Introduction of KR7A/KR7A-RAID
Features
1-1. Features of KR7A/KR7A-RAID Motherboard
This motherboard is designed for AMD Socket A Athlon™ XP, Athlon™ and Duron™ CPUs. It supports
the AMD Socket-A structure, with up to 3 GB (Unbuffered) or 4 GB (Registered) of memory, super I/O,
and Green PC functions.
The KR7A/KR7A-RAID uses the VIA VT8366A and VT8233 chipsets (KT266A) to make the
evolutionary move from PC 100/PC 133 SDRAM to PC 1600/PC 2100 DDR SDRAM, increasing the
speed of the system and memory buses from 100 MHz to 133 MHz. Its 200/266 MHz memory interface
supports the wide range of PC 1600/PC 2100 DDR SDRAM memory devices now on the market.
VIA VT8366A is a system bus controller, or northbridge, that houses the high-speed system elements
critical to overall system performance while also containing the system interface to the processor. The
key functions of the VT8366A System Controller include the 266 MHz Athlon System Bus, the 266 MHz
DDR Memory Subsystem, the AGP 4X/2X/1X modes Graphics Interface (AGP 2.0 Compliant) and the
33 MHz/32-bit PCI Bus Interface (PCI 2.2 Compliant), including arbiter.
DDR SDRAM is the newest memory standard, it provides the maximum translation bandwith and also
greatly improves data transaction delays. This feature improves whole system performance and speed,
especially multimedia environment applications.
The KR7A/KR7A-RAID has a built in Ultra DMA 100 function. This means that it provides speedier
HDD throughput boosting overall system performance. Ultra DMA 100 is the new standard for IDE
devices. It enhances existing Ultra DMA 33 technology by increasing both performance and data integrity.
This new high-speed interface almost doubles the Ultra DMA 66 burst data transfer rate to 100
Mbytes/sec. The result is maximum disc performance using the current PCI local bus environment.
Another benefit is you can connect four IDE devices in your system through either Ultra DMA 66 or
Ultra DMA 100. You will have more flexibility to expand your computer system.
KR7A-RAID’s built-in HighPoint HPT 372 chipset gives you the capability to support Ultra DMA 133.
Ultra DMA 133 is the newest standard for IDE devices. It provides two IDE channels (IDE3, IDE4) that
also support Ultra DMA 133 specifications, and it allows for four additional IDE devices in your
computer system. It can give you high performance and efficiency data transfer rate through the IDE
channels. This also means that your computer, in total, can connect up to eight IDE devices (IDE1 ~
IDE4). This allows for maximum expandability for future hardware demands. This chipset also supports
IDE RAID, inlcuding RAID 0, RAID 1 and RAID 0+1. This feature enables you to maximize your data
storage performance and security. (KR7A-RAID Only)
KR7A/KR7A-RAID provides high flexibility to users building AMD Socket A Athlon™ XP, Athlon™ and
Duron™ systems. It provides the option of 133MHz/133MHz CPU and memory bus combinations.
The KR7A/KR7A-RAID has built-in hardware monitoring functions (refer to Appendix B for detailed
information) to ensure a safe computing environment.

normally.
PCI slot 5 shares IRQ signals with the HPT 372 IDE controller (supports Ultra DMA 133). The
driver for HPT 372 IDE controller supports IRQ sharing with other PCI devices. But if you
install a PCI card that doesn’t allow IRQ sharing with other devices into PCI slot 5, you may
encounter some problems. Furthermore, if your Operating System doesn’t allow peripheral
devices to share IRQ signals with each other, such as Windows® NT for example, you can’t
install a PCI card into PCI slot 5. (KR7A-RAID Only)
HPT 372 IDE controller is designed to support high-speed and high performance mass storage
devices. Thus we suggest that you don’t connect non-disk devices that use ATA/ATAPI
interfaces, such as CD-ROM to HPT 372 IDE connector (IDE3 & IDE4). (KR7A-RAID Only)
This motherboard supports the standard bus speeds of 66MHz/100MHz/133MHz that are used
by specific PCI, processor and chipset specifications. Exceeding these standard bus speeds is
not guaranteed due to the specific component specifications.

User Friendly Instructions
Please read our instructions carefully and follow them step-by-step. Our objective is to enable the novice
computer user to perform the installation by himself. 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.
Diagram and Photos
This chapter contains many color drawings, diagrams and photos, we strongly recommend you read this
chapter use the PDF file that is stored on the CD-Title. Color improves the clarity and quality of the
diagrams. For the downloadable edition, as files larger than 3 MB are difficult to download, we will cut
the graphics and photo resolution to reduce the manual file size. In such this case, if your manual is

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
like 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.
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, don’t worry, you can still attach the spacers to the mounting holes. Just
cut the bottom portion of spacers (the spacer they may be a little hard to cut, so be careful with your
hands). 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, because the circuit wire may be near by the hole. Be careful, don’t let the screw contact
any 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 AMD Athlon™ XP, Athlon™ and Duron™
CPU
Note
! Installing a heatsink and cooling fan is necessary for heat to dissipate from your processor. Failing
to install these items may result in overheating and processor damage.
! The AMD Socket A processor will produce a lot of heat while operating, so you need to use a large
heat sink that is especially designed for the AMD socket A processor. Otherwise, it may result in
overheating and processor damage.
! If your processor fan and its power cable are not installed properly, never plug the ATX power
cable into the motherboard. This can prevent possible processor damage.
! Please refer to your processor installation manual or other documentation with your processor for
detailed installation instructions.
The AMD Socket A Athlon™ XP, Athlon™ and Duron™ processor installation is easy, like Socket 7
Pentium® processors before. Because it uses the “Socket A” ZIF (Zero Insertion Force) socket, you can
easily fix the processor firmly into position. Figure 2-3 shows you what the socket A looks like, and how
to open the lever. The socket A has more pins than the socket 7. Therefore, a Pentium level processor
cannot be inserted into a socket A.
When you raise the lever, you have to loosen the socket lock. Please raise the lever to the end, and
prepare to insert the processor. Next, you need to align the processor pin 1 to the socket pin 1. If you put
it in the wrong direction, you will not be able to insert the processor easily, and processor pins will not
fully go into the socket. If this is the case, please change the direction, until it easily and fully inserts into
the socket A. See Figure 2-4. At the same time check the processor temperature detection thermistor
height (if your motherboard has this component), then you can slowly insert the processor into the Scoket
A. Finally, you need to check that the processor edge and the Socket A edge is parallel. It should be
parallel and not tilted.
When you finish the above, push the lever down to its original position, you should feel the lever lock the
socket A. You have then finished the processor installation.
User’s Manual
Chapter 2

Heatsink Installation Hints
Because the processor will produce a lot of heat while operating, we suggest you use a heatsink approved
by AMD to be safe and to keep the processor temperature within normal operation temperatures. The
heatsink will be large and heavy, so the fixing plate has a strong tension. When you install the heatsink on
to the processor and its socket, you have to very carefully fix the fixing plate to the processor socket hook
on both sides. If you do not pay attention to this, you may make the fixing plate scratch the PCB surface
and cause circuit damage, break socket hooks or damage the die on the top of processor.
Please follow the sequence metioned below, Do Not
inverse the sequence. Otherwise, you may have a
situation like the photo on the left. Because of the
design of the CPU socket, the left side hooks are not
as strong as the right side hooks. If you follow our
suggestions you will prevent your processor and
socket from damage.
Note
Considering the chassis structure problem, please
always take off the motherboard from chassis,
before adding or removing a heatsink kit.
The proper procedure to install the heatsink kit:
First, install the processor into the processor socket.
Insert the heatsink left side fix plate into the
processor socket left side fix hooks. Make sure the fit
is very tight. Check the photo on the left.
KR7A/KR7A-RAID
Installing the Motherboard
2-5
Insert a flat screwdriver into the middle slot of the
right side fix plate and push down. Then you can
push the fix plate over the socket hooks on the right
side. Check the photo on the left.
Check the photo on the left. You have finished the
heatsink installation.
Now hold the whole heatsink and slightly shake it,
make sure the buttom right side of the heaksink does
not contact the right side of the Socket (see bottom
picture). Otherwise, the processor die does not have
proper contact with the heatsink. This situation may
cause processor damage.
Remember to install the heatsink fan power cable to
the CPU fan header on the motherboard.
Now you can reinstall the motherboard back into the
chassis.
When all above procedures done, you can connect
the ATX power cable to the motherboard.
If you have different types of heatsink kit, please
refer to the manual that came with the heatsink kit.
The left photo shows another type of heatsink fix
plate design. The install sequences are still the same,
from right side to left side. Just remember that.
We strongly recommand you to buy a heatsink
with three holes in the fix plate. This will provide
the best stabability and won’t cause the Socket fix
hooks to be broken or damaged.
The left photo shows the bottom right side of the
heaksink in contact with the right side of the Socket.
In this situation, the processor die does not properly
contact the heatsink. If you start the computer at this
monent, it will immediately cause the processor
damage. Always check this place when you finish the
heatsink installation.

2-3. Installing System Memory
This motherboard provides four 184-pin DDR DIMM sites for memory expansion. The DDR DIMM
sockets support 8Mx64 (64MB), 16Mx64 (128MB), 32Mx64 (256MB), 64Mx64 (512MB), and 128Mx64
(1024MB) or double density DDR DIMM modules. Minimum memory is 64 MB and the maximum
memory is 3 GB (Unbuffered) or 4 GB (Registered) DDR SDRAM. There are four memory module
sockets on the system board (for a total of eight banks). In order to create a memory array, following rules
must be followed.
! The memory array is 64 or 72 bits wide. (Depending on with or without parity)
! For those modules, we suggest that you be populate DIMM1 to DIMM4 in order.
! Supports single and double density DDR DIMMS.

Generally, installing DDR SDRAM modules to your
motherboard is an easy thing to do. You can refer to
Figure 2-5 to see what a 184-pin PC1600 & PC2100
DDR SDRAM module looks like.
Unlike installing SIMMs, DIMMs may be “snapped”
directly into the socket. Note: Certain DDR 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 DDR DIMM socket.
The following procedure will show you how to install a DDR DIMM module into a DDR 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 from your computer.
Step 2. Remove the computer’s chassis cover.
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 184-pin memory expansion DDR DIMM socket.
KR7A/KR7A-RAID
Installing the Motherboard
2-7
Step 5. Insert the DDR 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 2-6 for the details. This insures the DDR
DIMM module will be plugged into the socket in
one way only. Firmly press the DDR DIMM
module into DDR DIMM socket, making certain
the module is completely seated in the DDR
DIMM socket.
Step 6. Once the DDR 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 DDR DIMM module fully into the DDR DIMM socket, the eject tab should be
locked into the DDR DIMM module very firmly and fit into its indention on the both sides.
It is difficult to differentiate between the PC1600 and PC2100 DDR SDRAM modules from the exterior.
The only way you can identify them is to look at the sticker on the DDR SDRAM module. The sticker
will tell you which kind of structure module the DDR SDRAM is.
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 2-7 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.
Note
This components diagram will be slightly different because there are a number of models. We’ll use
the KR7A-RAID motherboard as standard; all descriptions of connector and header will be based on
the KR7A-RAID motherboard.
All connectors, headers and switches mentioned here, will depend on your system configuration. Some
User’s Manual

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.
Figure 2-7. All Connectors and Headers for the KR7A -RAID
First, Let’s see the headers that KR7A -RAID uses, and what their functions are. We will show you all the
connectors and headers.
(1). ATX1: ATX Power Input Connector
Attach the connector from the power supply to the
ATX1 connector here. Remember you have to push
the connector from the ATX power supply firmly to
the end with the ATX1 connector, insuring that you
have a good connection.
Note: Watch the pin position and the orientation.
KR7A/KR7A-RAID
Installing the Motherboard

Caution
If the power supply connectors are not properly attached to the ATX power supply, the power supply
or add-on cards may be damaged.
One end of AC power core connects to ATX power supply, and the other end (AC plug) will plug into
the wall outlet. Be aware that when facing the wall outlet, the round hole is in the middle. The right
side slot is called ground wire slot. It has a longer slot length than the left side slot. The left side slot is
called the live wire slot. You can use an electroscope to detect its polarity or you can use a voltage
meter to measure the voltage of both slot sides. If you insert an electroscope into the live wire slot, the
electroscope will light up. Using a voltage meter, you will find that the live wire slot will register a
higher voltage.
If you reverse the polarity of AC plug, it may affect the life of computer equipment, or cause an
electric shock when you touch the computer chassis. We suggest that you plug the computer AC plug
to a three-hole wall outlet for better safety and to avoid electric shock.
(2). FAN1, FAN2, FAN3, FAN4 & FAN5 header
Attach the connector from the CPU fan to the header
named FAN1 ond connector from the chassis fan to
the header FAN2 (These two fan headers have a
sense signal that can detect fan rotation speeds) or
FAN4 and attach the connector from the power fan to
FAN3 header. FAN5 is for the northbridge chipset
fan.
You must attach the CPU fan to the processor, or
your processor will work abnormally or may be
damaged by overheating. To prevent the computer
chassis internal temperature from getting too high,
also connect the chassis fan.
Note: Watch the pin position and the orientation
(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. This motherboard supports standard
IR transfer rates.
Note: Watch the pin position and the orientation

(12). IDE1, IDE2, IDE3 and IDE4 Connectors
This motherboard provides two IDE ports (IDE1 &
IDE2) to connect up to four IDE devices in Ultra
DMA 100 mode by Ultra DMA 66 ribbon cables.
Each cable has 40-pin 80-conductor and three
connectors, providing two hard drive connections
with the motherboard. Connect the single end (blue
connector) at the longer length of ribbon cable to the
IDE port on motherboard, and the other two ends
(gray and black connector) at the shorter length of the
ribbon cable to the connectors on hard drives.
KR7A-RAID’s built-in HighPoint HPT 372 chipset
gives you the capability to support Ultra DMA 133.
It provides two IDE channels (IDE3 & IDE4) that
also support Ultra DMA 133 specifications, and it
allows for four additional IDE devices in your computer system. Especially, if you want to connect two or
four HDDs to get RAID functions, it is very convenient for you to install the HDDs to IDE3 and IDE4.
See the Chapter 4 for detailed information about RAID settings.
If you want to connect two hard drives together through one IDE channel, you must configure the second
drive to Slave mode after the first Master drive. Please refer to the HDD documentation for jumper
settings. The first drive connected to IDE1 is usually referred to as “Primary Master”, and the second
drive as “Primary Slave”. The first drive connected to IDE2 is referred to as “Secondary Master” and the
second drive as “Secondary Slave”.
Keep away from connecting one legacy slow speed device, like CD-ROM, together with another hard
drive on the same IDE channel; this will decrease your integral system performance.

Introducing the BIOS
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, SOFT MENU™ III 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 the 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 even not 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 program 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 insuring 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:

exit the BIOS Setup menu.
Press Page Up/Page Down or +/- keys when you want to modify the BIOS parameters for the active
option.
Note
Parts of the screenshot may not same as you see on your screen, because the BIOS version may
change periodically. However, most of the functions covered in this manual will work. We suggest
that you go to our WEB site often to see if there are new manual releases. Then you can check the
newly updated BIOS items.
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 loose all CMOS data, therefore, we recommend that you write down all the parameters of
your hardware, or to put a label with these parameters on your hard disk.

! User Defined
&&&& Warning &&&&
The wrong settings of the multiplier and external clock in certain circumstances may cause CPU
damage
The wrong settings of the multiplier and external clock in certain circumstances may cause CPU
damage. Setting the working frequency higher than the specifications of PCI or of processor may
cause abnormal memory module functioning, system hangs, hard disk drive data loss, 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, for which should be
used for engineering testing only, 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.
" CPU FSB Clock (MHz):
You can increase the CPU FSB clock speed here. This means that you can independently increase
the CPU FSB clock speed. The DEC (decimal) numbers from 100 to 200 are available, with the
default setting at 100. You can change this setting to increase CPU FSB clock speed. CPU FSB
speed above the standard bus speed is supported, but not guaranteed due to the CPUspecs.
" Multiplier Factor:
Three are several settings, shown as below:
!x5
!x9.5
!x5.5
!x10
!x6
!x6.5
!x10.5 !x11
!x7

!over x13
" Speed Error Hold:
Two options are available: Disabled ) Enabled. 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 PCI
clock. 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“ key 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. But 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™ III. However, if the new CPU is slower than the old one (and is 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™ III.
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 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™ III again to set up the
parameters all over again.
CPU Power Supply:
This option allows you to switch between Default and User Define voltages.
! CPU Default: The system will detect the CPU type and select the proper voltage automatically. When
it is enabled, the option “Vcore 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”, “I/O Voltage” and “DDR Voltage” option lists by using the arrow up
and arrow down keys.
DQ Control:
This item can be set as Center DQ or Edge DQ. The default setting is Center DQ. When you set it to
Center DQ, the host side (processor side) controls the host bus sourcing clock delay time. If you set it to
Edge DQ, the edge side (northbridge side) controls the host bus sourcing clock delay time. Generally,
choosing Center DQ will be fine.
CPU Fast Command Decode:
Two options are available: Disable ) Enable. The default setting is Disable. With this setting, you may
select Enable if you want CPU decode address is 1T. We suggest you choose Disable for greatest stability.
Should you want increased performance then you can select Enable.

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 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.
IDE Primary Master:
Three settings are available: Auto, Manual and None. If you choose Auto, the BIOS will automatically
check what kind 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.
! CHS (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, that’s 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.
! Auto:
Just let the BIOS detect your HDD access mode and make the decisions.

and automatically set the DRAM running speed to the value stored in it.
KR7A/KR7A-RAID
Introducing the BIOS
3-15
What’s SPD?
SPD (Serial Presence Detect) is a feature available on a number of SDRAM/DDR SDRAM DIMM
modules that solves industry-wide compatibility problems by making it easier for the BIOS to
properly configure the system to fit SDRAM performance profiles.
The SPD device is a small serial EEPROM chip that stores various information about the DIMM
module’s size, speed, voltage, drive strength, latency timing and the number of row and column
addresses. When the BIOS reads these parameters during POST, it automatically adjusts the values in
the CMOS Advanced Chipset Features screen for maximum reliability and performance.
Without SPD, the BIOS (or user) must make assumptions about the DIMM’s parameters. Many users
have found that their system will not boot if they are using non-SPD SDRAM DIMMs. As SDRAM
and DDR SDRAM DIMM’s is running at very fast clock speed and there is less room for error. An
incorrect BIOS assumption about an SDRAM and DDR SDRAM DIMM’s parameters can have
serious consequences (e.g. failure to boot or fatal exception errors).
DRAM Timing:
Two options are available: Manual or Auto. The default setting is Manual. When set to “Auto”, the BIOS
will read the DRAM module SPD data and automatically set to the values stored in it. If you set to
“Manual”, the following five items will be available to let you make adjustments.
" DRAM CAS Latency:
Two options are available: 2 and 2.5. The default setting is 2.5. You can select SDRAM CAS

" Bank Interleave:
Three options are available: Disabled ) 2-Way ) 4-Way. The default setting is Disabled.
Depending on your SDRAM module structure, the 4-Way setting can offer the best performance. If
you choose the wrong setting, the computer system will not run in a stable manner. For detailed
information on your SDRAM module, please ask your SDRAM module manufacturer.
" Precharge to Active (Trp):
Two options are available: 2T or 3T. The default setting is 3T.
Trp timing value (Precharge time – time from precharge command to when back can be activated).
" Active to Precharge (Tras):
Two options are available: 5T or 6T. The default setting is 6T.
Tras timing value = Minimum bank active time from activate to precharge of same bank.
" Active to CMD (Trcd):
Two options are available: 2T or 3T. The default setting is 3T.

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:

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. The ACPI functions are always “Enabled”. 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 and Windows® 2000 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.

ACPI Suspend Type:
Two options are available: S1 (POS) or S3 (STR). The default setting is S1 (POS). Generally, ACPI has
six states: System S0 state, S1 state, S2 state, S3 state, S4 state, S5 state. 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.
KR7A/KR7A-RAID
Introducing the BIOS
3-27
! 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.
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 S1 were refer to ACPI Specification Rev. 1.0.

IRQ/Event Activity Detect:
The following is a list of IRQ’s (Interrupt ReQuests) and list of the events. When an I/O device wants to
gain the attention of the operating system, it causes an IRQ or event to occur. When the operating system
is ready to respond to the request, it interrupts itself and performs the service.

IRQs Activity Monitoring:
The following is a list of IRQ’s, Interrupt ReQuests. When an I/O device wants to gain the attention of
the operating system, it causes an IRQ to occur. When the operating system is ready to respond to the
request, it interrupts itself and performs the service.
When one of the specified events occurs, the count down for entry into the power saving mode goes back
to zero. Since the computer will enter a power saving mode only after a specified inactivity delay (time
specific for Doze, Standby and Suspend modes) and after there has been 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.

that prevents the operating system from booting.
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:
When resources are controlled manually, assign each system interrupt as one of the following types,
depending on the type of device using the interrupt:
Legacy ISA devices compliant with the original PC AT bus specification require a specific interrupt (such
as IRQ4 for serial port 1). PCI PnP devices comply with the Plug and Play standard, whether designed
for the PCI or legacy ISA bus architecture.
Two options are available: Auto (ESCD) or Manual. The default setting is Auto (ESCD). The Award Plug
and Play BIOS has the capability to automatically configure all boot and Plug and Play compatible
devices. If you select Auto (ESCD), all of the interrupt request (IRQ) fields become unselectable, as the
BIOS automatically assigns them.
IRQ Resources:
If you have trouble in assigning the interrupt resources automatically, you can select Manual to set which
IRQis assigned to which PCI device or reserve it. See the screen shot below.

MPEG card.
Assign IRQ For VGA:
Two options are available: Disabled or Enabled. The default setting is Enabled. Name the interrupt
request (IRQ) line assigned to the USB/VGA/ACPI (if any) on your system. Activity of the selected IRQ
always awakens the system.
You can assign an IRQ for the either PCI or AGP VGA or Disabled.
Assign IRQ For USB:
Two options are available: Disabled or Enabled. The default setting is Enabled. If you need free up
another IRQ, you can choose to disable this item to an IRQ. However, some situations in Windows® 95
may cause the USB port to malfunction or experience other problems!
PIRQ_0 Use IRQ No. ~ PIRQ_3 Use IRQ No.:
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. This
means that the system can specify the fixed IRQ number for the device installed on the PCI slots (PCI slot
1 to PCI slot 6). This is a useful function for when you want to fix the IRQ for a specific device.
For example, if you want to move your hard disk to another computer and don’t want to re-install
Windows® NT or Windows® 2000, you can simply specify the IRQ for the device installed on the new
computer to fit the original computer settings.
This feature is for the operating system that will record and fix the PCI configuration status if you want to
change it.

Note
! PCI slot 1 shares IRQ signals with the AGP slot.
! PCI-4 and USB controllers share an IRQ.
! If you want to install two PCI cards into those PCI slots that share IRQ with one another at the
same time, you must make sure that your OS and PCI devices’ driver supports the IRQ sharing
function.
! PCI slot 5 shares IRQ signals with the HPT 372 IDE controller (supports Ultra DMA 133). The
driver for HPT 372 IDE controller supports IRQ sharing with other PCI devices. But if you install
a PCI card that doesn’t allow IRQ sharing with other devices into PCI slot 5, you may encounter
problems. Furthermore, if your Operating System doesn’t allow peripheral devices to share IRQ
signals with each other, such as Windows® NT for example, you can’t install a PCI card into PCI
slot 5. (KR7A-RAID Only)
! HPT 372 IDE controller is designed to support high-speed and high performance mass storage
devices. Thus, we suggest that you don’t connect non-disk devices that use ATA/ATAPI
interfaces, such as a CD-ROM, to HPT 372 IDE connector (IDE3 & IDE4). (KR7A-RAID Only)

We will use the SE6 motherboard as an example. All other models follow the same process. First, know
your motherboard’s model name and version number. You can find it on one slot or at the back of the
motherboard. Each motherboard always has the label at the same place as shown in the photo below.
You will find the model name and version on the white sticker.
2. Know the current BIOS ID.
For example, in this case, the current BIOS ID is “00”. If you already have the latest BIOS, no any update
action is necessary. If your BIOS is not the latest BIOS, go on to the next step.

Appendix C
Please set the first boot sequence as “floppy” in BIOS and boot off the floppy disk.
7. Flash the BIOS in pure DOS mode.
After successfully booting off of the floppy, execute the flash utility according to these instructions.
Note
We strongly recommend you use the above parameters following “awdflash” to flash your BIOS. DO
NOT just type “awdflash se6_sw.bin” without the above parameters following the .bin file.
Note
The Award flash utility can not be completed under a Windows® 95/98 or Windows® NT
environment, you must be in a pure DOS environment.
You should check which BIOS file is to be used with your motherboard, don't flash with the wrong
BIOS file. Otherwise, you may cause system malfunctions.
Note
Please do not use the Award flash memory writer version that earlier than Version 7.52C to flash your
KR7A/KR7A-RAID motherboard BIOS. Otherwise, it may cause flash fail or un-anticipate problems.
Note
During the updating, the progress will be measured by white blocks. The last four blue blocks of the
flash update process represent the “BIOS boot block”. The BIOS boot block is used to prevent the
BIOS from becoming corrupt during programming. It should not be programmed every time. If this
“BIOS boot block” remains intact when the BIOS becomes corrupt during programming, then you
can boot from a bootable floppy next time you boot your computer. This allows you to flash your
BIOS again without the need for technical support from the dealer.

Motherboard Troubleshooting:
Q & A:
Q: Do I need to clear the CMOS before I use a new motherboard to assemble my new computer
system?
A: Yes, we highly recommend that you clear the CMOS before installing a new motherboard. Please
move the CMOS jumper from its default 1-2 position to 2-3 for a few seconds, and then back. When
you boot up your system for the first time, follow the instructions in the user's manual to load the
optimized defaults.
Q: If my systems hang when I update the BIOS or set the wrong CPU parameters, what should I
do?
A: Whenever you update the BIOS or if the system hangs due to wrong CPU parameters setting, always
clear CMOS jumper before booting up again.
Q: How can I get a quick response to my request for technical support?
A: Be sure to follow the guidelines as stated in the “Technical Support Form” section of this manual.
If you have a problem during operation, in order to help our technical support personnel quickly
determine the problem with your motherboard and give you the answers you need, before filling in the
technical support form, eliminate any peripheral that is not related to the problem, and indicate it on
the form. Fax this form to your dealer or to the company where you bought the hardware in order to
benefit from our technical support. (You can refer to the examples given below)
Example 1: With a system including: motherboard (with CPU, DRAM, COAST...) HDD, CD-ROM,
FDD, VGA CARD, MPEG CARD, SCSI CARD, SOUND CARD, etc. After the system
is assembled, if you cannot boot up, check the key components of the system using the
procedure described below. First remove all interface cards except the VGA card and try
to reboot.
. If you still cannot boot up:
Try installing another brand/model VGA card and see if the system will start. If it still
does not start, note the VGA card model, motherboard model, Bios identification
number, CPU on the technical support form (refer to main instructions), and describe
the problem in the problem description space provided.
. If you can boot up:
Insert the interface cards you have removed back into the system, one by one and try
to start the system each time you insert a card, until the system will not start. Keep the
VGA card and the interface card that caused the problem inserted on the motherboard,
remove any other cards or peripheral, and start again. If you still cannot start, note the
information related to both cards in the add-on Card space provided, and don’t forget
to indicate the motherboard model, version, BIOS identification number, CPU (refer
to main instructions), and give a description of the problem.

Example 2: With a system including the motherboard (with CPU, DRAM, COAST...) HDD,
CD-ROM, FDD, VGA CARD, LAN CARD, MPEG CARD, SCSI CARD, SOUND
CARD, after assembly and after having installed the Sound Card Driver, when you restart
the system, when it runs the Sound Card Driver, it resets automatically. This problem
may be due to the Sound Card Driver. During the Starting DOS… procedure, press
SHIFT (BY-PASS) key, to skip CONFIG.SYS and AUTOEXEC.BAT; edit
CONFIG.SYS with a text editor, and in function the line that loads the Sound Card
Driver, add a remark REM, in order to disable the Sound Card Driver. See the example
below.

DEVICE=C:\DOS\HIMEM.SYS
DEVICE=C:\DOS\EMM386.EXE HIGHSCAN
DOS=HIGH, UMB
FILES=40
BUFFERS=36
REM DEVICEHIGH=C:\PLUGPLAY\DWCFGMG.SYS
LASTDRIVE=Z
Restart the system. If the system starts and does not reset, you can be sure that the
problem is due to the Sound Card Driver. Write down the Sound Card model,
motherboard model, BIOS identification number on the technical support file (refer to
main instructions), and describe the problem in the space provided.

6. Reporting Compatibility Problems to ABIT. Because of tremendous number of email messages we
receive every day, we are forced to give greater weight to certain types of messages than to others.
For this reason, any compatibility problem that is reported to us, giving detailed system configuration
information and error symptoms, will receive the highest priority. For the other questions, we regret
that we may not be able to reply directly. But your questions may be posted to the internet news group
in order that a larger number of users can have the benefit of the information. Please check the news
group from time to time.
