HARDWARE SETUP
2-1 CPU INSTALLATION
WARNING:
• Make sure that +5V DVC and +3.3 DVC capabilities of your power supply
are suitable for the processor.
• Any attempt to operate the AMD Athlon or Duron processor without a suitable cooling Fan will result in permanent damage to the processor and
potentially other component within the system.
1. Pull the lever sideways away from the socket, and then raise the lever up
to a 90-degree angle.
SOCKET 462
2. Take note of the red circle as below picture. While inserting the CPU into
the socket, you can find out there is a definite pin orientation for CPU and
socket.

2-2 MEMORY INSTALLATION
WARNING!!!
• Make sure that you unplug your power supply when adding or removing memory modules or other system components. Failure to do so
may cause severe damage to both your mainboard and expansion
cards.
• Be careful when inserting or removing DIMM, forcing a DIMM in or out
of a socket can be damaged the memory module or the socket. Some of
DIMMs contain EDO or FTP DRAM. These DIMM types are incompliant
with the motherboard, the M/B only supports 3.3V true SDRAM DIMMs
Installing DIMM
• Make sure you have the correct memory module type for your
motherboard.
• Insert the module(s) as shown, DIMMs have 168-pins and two notches
that will match with the onboard DIMM socket, memory modules are
installed by inserting them straight into the slot until they “click” into
place. They only fit in one direction so do not force them into place.

IMPORTANT:
• You may figure out the correct processor type by processor’s OPN
(Ordering Part Numbers), select correct CPU external frequency is
key to ensure reliable operation.
• Incorrect CPU external frequency or overclocking are not guaranteed
to be stable, we strongly recommended to leave “SW1” at default
setting or legal operation.

75KAV/75KAV-X
2-7 BUS RATIO SELECT
• The AMD Athlon and Duron processor provides four Frequency ID
signals (FID) to the system controller to indicate the SYSTCLK
multiplier at which the processor core operates, This mechanism is
automatic. The board maker does not guarantee “Bus Ratio” can be selected
if the processor does not support it.
• When LED “SSF1” light is on, meaning that Bus Ratio Select Function is
enabled.

• Both ISA and PCI expansion cards may require IRQs. System IRQs are
available to cards installed in the ISA expansion bus first, then any remaining IRQs are available to PCI cards. Currently, there are two types of ISA
cards.
• The original ISA expansion card design, now referred to as “Legacy” ISA
card, requires that you configure the card’s jumpers manually and then
install it in any available slot on the ISA bus. To see a map of your used and
free IRQs in Windows 98, the Control Panel in My Computer, contains a
System icon, which gives you a Device Manager tab. Double-Clicking on a
specific hardware device gives you a Resources tab which shows the Interrupt number and address. Double-Clicking Computers to see all the inter-
rupts and addresses for your system. Make sure that no two devices use
the same IRQ or your computer will experience problems when those two
devices are in use at the same time.

CHAPTER 4
BIOS SETUP
4-1 INTRODUCE THE BIOS
• BIOS stands for Basic Input Output System. It is sometimes called ROM
BIOS because it is stored in a Read-Only Memory(ROM) chip on the
motherboard. BIOS is the first program to run when you turn on your
computer.
• BIOS performs the following functions:
1. Initializing and testing hardware in your computer(a process called “POST”,
for Power On Self Test).
2. Loading and running your operating system.
3. Helping your operating system and application programs to manage your
PC hardware by means of a set of routines called BIOS Run-Time Service.
4-2 WHAT IS BIOS SETUP
• Setup is an interactive BIOS program that you need to run when:
1. Changing the hardware on your system. (for example: installing a new
Hard Disk etc,.)
2. Modifying the behavior of your computer. (for example: changing the sys-
tem time or date, or turning special features on or off etc,.)
3. Enhancing your computer’s behavior. (for example: speeding up perfor-
mance by turning on shadowing or caching)
4-3 HOW TO RUN BIOS SETUP
• One way of running SETUP is to press a special function key or key combination during POST, before the operating system is loaded during POST,
the BIOS usually displays a prompt such as:
Press DEL to enter SETUP
4-4 WHAT IS CMOS
• CMOS is a special kind of memory maintained by a battery after you turn
your computer off. The BIOS uses CMOS to store the settings you selected
in SETUP. The CMOS also maintains the internal clock. Every time you
turn on your computer, the BIOS Looks in CMOS for the settings you se-
45
75KAV/75KAV-X
lected and configures your computer accordingly. If the battery charge runs
too low, the CMOS content will be lost and POST will issue a “CMOS invalid” or “CMOS checksum invalid” message. If this happens, you may
have to replace the battery. After the battery is replaced, the proper settings will need to be stored in SETUP.
4-5 WHAT IS POST
• POST is an acronym for Power On Self Test. It’s a traditional name for the
routines that the BIOS uses to test and initializes the devices on your system when the PC is powered on. Its meanings has grown to include anything the BIOS does before the operating system is started. Each of POST
routines is assigned a POST code, an unique number which is sent to I/O
port 080h before the routine is executed.
4-6 BIOS UPGRADE
• Motherboards incorporate the system BIOS in a Flash memory component.
Flash BIOS allows user upgrades without the need to replace an EPROM
component.
• The upgrade utility fits on a floppy diskette and provides the capability to
save, verify, and update the system BIOS. The upgrade utility can be run
from a hard disk drive or a network drive, but no memory managers can be
installed during upgrades.
4-6.1 BEFORE UPGRADE BIOS
• It is recommended that you save a copy of the original motherboard BIOS
along with a Flash EPROM Programming utility(AWDFLASH.EXE) to a
bootable floppy disk in case you need to reinstall the BIOS later.
4-6.2 UPGRADE PROCESS
Note: Normally, to upgrade BIOS that is unnecessary if the system is working fine
without any problem, user should upgrade the BIOS unless you experienced
incompatible problem or need BIOS upgrade to create new features. However,
please read all information in this section before upgrading.
46
75KAV/75KAV-X
“AWDFLASH.EXE” is a Flash EPROM Programming utility that up dates the
BIOS by uploading a new BIOS file to the programmable flash ROM on the
motherboard, This program only works in pure DOS environment, the utility
can not be worked in win95/98, ME, NT or WINDOWS 2000 environment.
Upgrading the system BIOS
Set 1. Pleas visit the board maker’s website, download the newest BIOS file and
newest award flash utility “AWDFLASH.ESE” for the motherboard. The BIOS
file you downloaded will be a *. bin format.
Step 2. Create a bootable diskette. Then copy the BIOS file and award flash utility
