IMPORTANT:
You may figure out the correct processor type by processors OPN (Ordering Part Numbers). Correct CPU external frequency is key to ensure reliability of your system. Incorrect CPU external frequency or overclocking might cause unstable performance, so we strongly recommend to leave SW1 at default setting or legal operation.
2-5-3 BUS RATIO SELECT (BY SW2 DIP1-4/JP17)
The AMD Athlon and Duron processors provide four Frequency ID signals
(FID) respectively via DIP 1 to DIP4 of SW3 for the system controller to specify the SYSTCLK multiplier at which the processor core operates. Normally, the multiplier (or bus ratio) is detected automatically by FID. Therefore, if the processor does not support the function, then Bus Ratio can not be selected. When JP17 is ON, LED LED1 will be on. It means that bus ratio select function is enabled. So as long as your CPU supports bus ratio select function, then the bus ratio can be selected by users.

*Note:

Setting of multipler 12. 5x or above will depend on the type of CPU on board.

Chapter4 BIOS Setup

BIOS SETUP

THE BIOS

BIOS stands for Basic Input and Output System. It is sometimes called ROM BIOS because it is stored in a Read-Only Memory (ROM) chip on the mainboard. 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.
THIS CHAPTER CONTAINS THE FOLLOWING TOPICS : Q J N=WHAT IS BIOS SETUP Q J O=HOW TO RUN BIOS SETUP Q J P=WHAT IS CMOS Q J Q=WHAT IS POST Q J R=BIOS UPGRADE Q J S =BIOS SETUP

4-1 WHAT IS BIOS SETUP

BIOS Setup is an interactive BIOS program that you need to run when: 1. Changing the hardware of your system. (for example: installing a new Hard Disk etc.) 2. Modifying the behavior of your computer. (for example: changing the system time or date, or turning special features on or off etc.) 3. Enhancing your computers behavior. (for example: speeding up performance by turning on shadowing or cache)
4-2 HOW TO RUN BIOS SETUP
To access BIOS setup menu, press < DEL > key after POST, and before the OS is loaded. The BIOS usually display the following message:

Press DEL to enter SETUP

4-3 WHAT IS CMOS
CMOS is the memory maintained by a battery. The BIOS uses CMOS to store the settings you have selected in SETUP. The CMOS also maintains the internal clock. Every time you turn on your computer, the BIOS Looks into CMOS for the settings you have selected and configures your computer accordingly. If the battery is out of power, the CMOS data will be lost and POST will issue a CMOS invalid or CMOS checksum invalid message. If this happens, you have to replace the battery and do some proper settings in SETUP.

4-4 WHAT IS POST

POST is an acronym for Power On Self Test. POST will that all things the BIOS does before the operating system is started. Each of POST routines is assigned a POST code, a unique number which is sent to I/O port 080h before the routine is executed.

4-5 BIOS UPGRADE

System BIOS is incorporated into a Flash memory component of the mainboard. Flash BIOS allows user to upgrade BIOS without the need to

Chapter4 BIOS Setup replace an EPROM component. The upgrade utility can be loaded on a floppy diskette and used to provide the capability to save, verify, and update the system BIOS. The upgrade utility can also be run from a hard disk drive or a network drive.
4-5-1 BEFORE UPGRADING BIOS
It is highly recommended that you save a copy of the original mainboard BIOS along with a Flash EPROM Programming utility (AWDFLASH.EXE) to a bootable floppy disk in case you need to reinstall the BIOS later.

4-5-2 UPGRADE PROCESS

Note: Normally, to upgrade BIOS is unnecessary if the system is working
fine without any problem. Users should not upgrade the BIOS unless you experience incompatible problems or need to create new features. However, please read all information in this section before upgrading. AWDFLASH.EXE is a Flash EPROM Programming utility that updates the BIOS by uploading a new BIOS file to the programmable flash ROM on the mainboard, This program works in DOS environment only, the utility can not be executed in win95/98, ME, NT or WINDOWS 2000 environment.
Upgrading the system BIOS
Step 1. Please visit the board makers website, download latest BIOS file and award flash utility AWDFLASH.EXE. The BIOS file format will be *.bin, of which * stands for the specific file name. Step 2. Create a bootable diskette. Then copy the BIOS file and award flash utility AWDFLASH.EXE into the diskette. Step 3. Insert the diskette into drive A, reboot your system and boot from the diskette. Step 4. Type awdflash *.bin /sn/py/cc and then press <Enter> to run BIOS upgrade program. (*.bin depends on your mainboard model and version code. Instead of typing * , you should type the specific file name for your
75KAV/75KAV-X specific mainboard.) Step 5. Please press <F1> or <F10> to exit or reset your system, Warning ! If the message Write Fail appears while Award FLASH MEMORY WRITER is verifying Flash memory, just repeat the process. Please DO NOT reset or turn off the system. If the award memory flash utility is not able to update the BIOS successfully, your system may not be able to boot up. Step 6. You will need a message CMOS checksum error-Default loaded during booting the system. Press <Del> to run CMOS setup utility, then reload LOAD SETUP DEFAULTS or Load Optimized Defaults and save this change.

Disabled: No warning message will appear when there is something attempting to access the boot sector or hard disk partition table. NOTE: Many diagnostic (or boot manager) programs which attempt to access the boot sector table can cause the above warning message. If you will be running such a program, we recommend that you disable the virus protection first. CPU Internal Cache/ Cache memory is additional memory that is much External Cache faster than conventional DRAM (system memory). CPUs from 486-type up contain internal cache memory, and most, but not all, modern PCs have additional (external) cache memory. When the CPU requests data, the system transfers the requested data from the main DRAM into cache memory, for even faster access by the CPU.

If you need to delete the password entered before, choose the Supervisor Password and press <Enter>. It will delete the password that you have entered before. 7. Move the cursor to Save & Exit Setup to save the option you have just configured; otherwise the old password will still be there the next time you turn your system on. 8. Press <Enter> to exit to the Main Menu.
NOTE: If you forget or lose the password, the only way to access the
system is to clear the CMOS RAM. All setup informations will be lost and you need to run the BIOS setup program again.
