2-4 JUMPER DEFINITIONS

• The figure below shows the location fo the motherboard’s jumper blocks.

CAUTION

• Do not move the jumper with the power on. Always trun off the power and
unplug the power cord from the computer before changing the jumper.
Otherwise, the motherboard could be damaged.

CPU FAN

FAN1/FAN2: ONBOARD FAN (12V)

FAN2

FAN1

SYSTEM FAN

Those connectors support processor/system/chassis cooling fan
with +12V. Those support three pin head connector. When con­necting the wire to FAN connectors, user should give attention that
the red wire is the positive and should be connected to the +12V,
the black wire is Ground and should be connected to GND. If your
motherboard has Hardware Monitor chipset on-board, you must
use a specially designed fan with speed sensor to take advantage
of this function.
For fans with fan speed sensor, every rotation of the fan will send
out 2 pulses. System Hardware Monitor will count and report the
fan rotation speed.

NOTE 1: Always consult vendor for proper CPU cooling fan.
NOTE 2: CPU FAN supports the FAN control. You can install PC

Alert utility. This will automatically control the CPU FAN
speed according to the actual CPU temperature.

VIO allows you to select the voltage supplied to the DRAM,
chipset, AGP, PCI, and the CPU’s I/O buffer. The default voltage
(3.3V) should be used unless processor overclocking requires

a higher voltage.

NOTE! Using a higher voltage may help when overclocking

but may result in the shortening of your computer
components’s life. It is strongly recommended that you
leave this setting on its default.

NOTE : You can clear CMOS by shorting 2-3 pin when the

system is POWER OFF. Then, return to 1-2 pin
position (default). It may damage the motherboard if
clearing the CMOS in POWER ON status. Unplug
the power cord from power supply before clearing
CMOS will be a best bet for user.

• 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 configurate 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 inter­rupts 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-

75KV/75KV-X

38

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

• “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 motherboard. This file only works in DOS mode. To determine the BIOS
version, check the release date displayed on the top of your screen during
bootup. Newer dates represents a newer BIOS file.

75KV/75KV-X

39

Create a Boot Floppy (using a DOS system to create the bootable floppy)

• Place an unformatted floppy diskette in the floppy drive and format the
floppy using the /S option.

Example: format a: /s

• Alternatively, place a formatted floppy in the floppy drive and use the “sys”
command.

Example: sys a:

Create the BIOS Upgrade Floppy Diskette

• Download both the newest BIOS file and AWDFLASH.EXE file via
motherboard maker’s website.

• The BIOS file you downloaded will be a *.bin format.

• Copy those two indispensable files to a bootable formatted floppy diskette.

Example: copy awdflash.exe a:
Example: copy *.bin a:

Upgrading the system BIOS

• Place the bootable floppy containing the BIOS into Drive A: of the system
that you want ot upgrade and boot the system while thefloppy diskette is in
the drive.

• When booting is finished, type awdflash *.bin /sn/py/cc/r and then press
<Enter> to run BIOS upgrade program. (*.bin depends on your motherboard
model and version code)

The parameters of AWDFLASH.EXE

/sn: No original BIOS backup
/py: Program flash memory
/cc: Clear CMOS data after programming
/r : Reset system after programming

NOTE: User can type AWDFLASH /? to get further details about

parameters. Wrong usage of parameter will damage the BIOS
information, so that we strongly recommend user to leave pa­rameters away unless you realize their function.

75KV/75KV-X

40

• Then appears a program window as below:

• After upgraded, the system will reboot itself automatically.

• NOTE: You will see a message “CMOS checksum error - Default loaded”

during booting the system. Please press <Del> to run BIOS program,
then reload “LOAD SETUP DEFAULTS” and save this change.

The following is a list of IRQ’s (Interrupt ReQuests), which can be exempted
much as the COM ports and LPT ports above can. When an I/O device
wants to gain the attention of the operating system, it signals this by causing
an IRQ to occur. When the operating system is ready to respond to the
request, it interrupts itself and performs the service. When set On, activity
will neither prevent the system from going into a power management mode
nor awaken it.
