Precautions
Static Electricity Damage:
Static electricity can easily damage your motherboard.
Observing a few basic precautions will help safeguard
against damage that could result in expensive repairs.
Please read the following before beginning installation.
1. Keep the motherboard and other system components in their anti-static
packaging until you are ready to install them.
2. Touch a grounded surface before you remove any system component from its
protective anti-static packaging. Unpacking and installation should be done
on a grounded, anti-static mat. The operator should be wearing an anti-static
wristband, grounded at the same points as the anti-static mat.
3. After removing the motherboard from its original packaging, only place it on
a grounded, anti-static surface, component side up. Immediately inspect the
board for damage. Due to shifting during shipping, it is suggested that the
installer press down on the entire socket ICs to ensure they are properly
seated. Do this only with the board placed on a firm flat surface.
4. During configuration and installation touch a grounded surface frequently to
discharge any static electrical charge that may have built up in your body.
The best precaution, as stated above, is to wear a grounded wrist strap.
When handling the motherboard or an adapter card, avoid touching its
components. Handle the motherboard and adapter cards either by the edges
or by the adapter card case-mounting bracket.
Misplaced Jumper Damage:
There are critical headers used for connectors or power
sources. These are clearly marked separately from the
jumpers listed in “Motherboard Layout”. Incorrectly setting
jumpers and connectors may lead to damage to your
motherboard. Please pay special attention not to connect
these headers in the wrong directions.

Are all DRAM modules installed properly? (Sec. 3.3)
Are all expansion cards inserted, (Modem…. etc.)?
(Sec. 3.4)
Are all connectors described in Section 3.5 properly
connected to their variable devices? (Sec. 3.5)
l Yes, I have checked and assured the above steps!
Now get ready to turn on your device by following these steps.
Mount your motherboard to the chassis frame and close the
chassis cover.
Switch off all power.
Connect the power supply cord to inlet of the system case.
Connect the power supply cord into an outlet of power
supply.
Connect monitor signal cable to system VGA port, and the monitor power cord to
power outlet.
Turn on monitor and system power.
Once Powered On
The power LED on the front panel of the system case will light. For ATX power
supplies, the system LED will light when the ATX power switch is pressed.
The system will then perform “power-on” tests for each item, one at a time. Additional
messages will appear on screen at this time. If the screen blinks or the tests stops more
than 30 seconds, the system may have failed the
“power-on” test. If this happens, recheck the above
steps or call your retailer for assistance.
If all of the “power-on” tests pass, you are ready to
enter BIOS setup. Do this now by holding down the
<Delete> button on the keyboard. Follow the
instructions in the next chapter, BIOS SETUP.

BIOS, which is stored in a Flash EEPROM
and can be upgraded by a floppy disk-based
program. The BIOS has a built-in Setup
Program which allows users to modify the
basic system configuration settings. The
settings are then stored in a dedicated
battery-backed memory, called CMOS
RAM that retains the information when the
power is turned off. The BIOS provides critical low-level support for the system’s
central processing, memory and I/O subsystems. The AWARD BIOS has been
customized by adding important, nonstandard, features such as virus and password
protection, power management, and detailed fine-tuning of the chipset which controls
the system. The remainder of this manual is intended to guide you through the process
of configuring your system using the BIOS Setup.
4.1 How to enter BIOS Setup
The AWARD BIOS is immediately activated when you first turn on the computer. The
BIOS reads system configuration information in CMOS RAM and begins the process of
checking the system and configuring it through the “power-on self test”, (POST). When
these preliminaries are completed, the BIOS searches for an operation system on the
data storage devices (hard drive, floppy drive, etc.). The BIOS launches the operating
system and hands over control of system operation to it.
To begin Setup, press the <Delete> key during boot-up before or while a message
similar to this appears briefly at the bottom of the screen during POST, (Power On Self
Test):
Press DEL if you want to enter SETUP
If the above message disappears before you have responded and you still wish to enter
Setup, reboot the system to try again by pressing the “RESET” button on the system
case. You can also restart by simultaneously pressing the <Ctrl>, <Alt> and <Delete>
keys.
Press F1 to continue, DEL to enter SETUP

4.1.2 Getting Help
Press F1 to pop up a small help window that describes the appropriate keys to
use and the possible selections for the highlighted item. To exit the Help
Window press Esc or the F1 key again.
4.1.3 In Case of Problems
If after making and saving system changes with Setup, you discover that your
computer is no longer able to boot-up, the Award BIOS supports an override to
the CMOS settings that resets your system to its default configuration.

The best advice is to alter only settings that you thoroughly understand. In
particular, do not change settings in the Chipset screen without a good reason.
Your system manufacturer has carefully chosen the Chipset defaults for the best
performance and reliability. Even a seemingly small change to the Chipset
setup may cause the system to become unstable.

The BIOS determines the day of the week from the other date information. This field is
for information only. Press the left or right arrow key to move to the desired field (date,
month, year). Press the PgUp or PgDn key to increment the setting, or type the desired
value into the field.
Time
The time format is based on the 24-hour military-time clock. For example, 1 p.m. is
13:00:00. Press the left or right arrow key to move to the desired field. Press the PgUp
or PgDn key to increment the setting, or type the desired value into the field.
Hard Disks
The BIOS supports up to 4 IDE drives. This section does not show information about
other IDE devices, such as a CD-ROM drive, or other hard drive types, such as SCSI
drives.
NOTE: We recommend that you select type AUTO for all Hard disks.
4. BIOS SETUP
The BIOS can automatically detect the specifications and optimal operating mode of
almost all IDE hard drives. When you select type AUTO for a hard drive, the BIOS
detects its specifications during POST, each time the system boots.
If you do not want to select drive type AUTO, other methods of selecting the drive type
are available:
1) Match the specifications of your installed IDE hard drive(s) with the
preprogrammed values for drive types 1 through 45.
2) Select USER and enter values into each drive parameter field.
3) Use the IDE HDD AUTO DECTECTION function in Setup.
The following is a brief explanation of drive specifications:
• Type: The BIOS contains a table of pre-defined drive types. Each defined drive type
has a specified number of cylinders, number of heads, write precompensation factor,
landing zone, and number of sectors. Drives whose specifications do not
accommodate any pre-defined type are classified as type USER.
• Size: Disk drive capacity (approximate). Note that this size is usually slightly greater
than the size of a formatted disk given by a disk-checking program.
• Cyls: Number of cylinders
• Head: Number of heads
• Precomp: Write precompensation cylinder
• Landz: Landing zone
• Sector: Number of sectors
• Mode: Auto, Normal, large, or LBA
• Auto: The BIOS automatically determines the optimal mode.
• Normal: Maximum number of cylinders, heads, and sectors supported are 1024, 16,
and 63.
• Large: For drives that do not support LBA and have more than 1024 cylinders.
• LBA (Logical Block Addressing): During drive accesses, the IDE controller
transforms the data address described by sector, head, and cylinder number into a
physical block address, significantly improving data transfer rates. For drives with
greater than 1024 cylinders.
4. BIOS SETUP
Drive A/B type
Select the correct specifications for the diskette drive(s) installed in the computer.
None No diskette drive installed

CGA 40 Color Graphics Adapter, power up in 40 column mode.
CGA 80 Color Graphics Adapter, power up in 80 column mode.
MONO
Halt on
During the “power-on self-test”, (POST), the computer halts if the BIOS detects any
hardware errors. You can instruct the BIOS to ignore certain errors during POST and
continue the boot-up process. These are the selections:
No errors POST does not stop for any errors.
All errors
All, But keyboard
All, But Diskette
All, But Disk/Key
Enhanced Graphics Adapter/Video Graphics Array. For EGA, VGA,
SEGA, SVGA or PGA monitor adapters.
Monochrome adapter, includes high resolution monochrome
adapters.
If the BIOS detects any non-fatal error, POST stops and
prompts you to take corrective action.
POST does not stop for a keyboard error, but stops for all
other errors.
POST does not stop for diskette drive errors, but stops for all
other errors.
POST does not stop for a keyboard or disk error, but stops for
all other errors.
4. BIOS SETUP
Memory
Values in the Memory field are for your information only and cannot be changed. The
fields show the total installed “Random Access Memory”, (RAM), and amounts
allocated to base memory, extended memory, and other (high) memory. RAM is
counted in kilobytes (KB: approximately one thousand bytes) and megabytes (MB:
approximately one million bytes).
RAM is the computer's working memory, where the computer stores programs and data
currently being used, so they are accessible to the CPU. Modern personal computers
may contain up to 64 MB, 128 MB, or more.
Base Memory
Base memory is typically 640 KB. It is also referred to as “conventional memory”.
The DOS operating system and conventional applications utilize this type of
memory.
Extended Memory
Extended Memory is above the 1 MB boundary. Early IBM personal computers
could not use memory above 1 MB, but current PCs and their software can use
extended memory.
Other Memory
Between 640 KB and 1 MB; often called High memory. DOS may load
“Terminate-and-Stay-Resident”, (TSR), programs such as device drivers, in this
area, to free as much conventional memory as possible for applications. Lines in
your CONFIG.SYS file beginning with “LOADHIGH” will load programs into high
memory.
Total Memory
System total memory is the sum of base memory, extended memory, and other
memory.

External Cache
Cache memory is additional memory that is much faster than conventional DRAM
(system 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. The
External Cache field may not appear if your system does not have external cache
memory.
Quick Power On Self Test
This enables your system to do a “Quick Self Test” after Power on.
4. BIOS SETUP
Boot Sequence
The original IBM PCs loaded the DOS operating system from drive A (floppy disk).
Because of this, IBM PC-compatible systems are designed to search for an operating
system first on this drive, and then on drive C (hard disk). However, the BIOS now
offers 10 different boot sequence options of three drives each. In addition to the
traditional drives A and C, options include IDE hard drives D, E, and F, as well as an
SCSI hard drive and a CD-ROM drive.
Swap Floppy Drive
This field is effective only in systems with two floppy drives. Selecting “Enabled”
assigns physical drive B to logical drive A, and physical drive A to logical drive B.
Boot Up Floppy Seek
When “Enabled”, the BIOS tests (seeks) floppy drives to determine whether they have
40 or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720 KB, 1.2
MB, and 1.44 MB capacity all have 80 tracks. Because very few modern PCs have 40track floppy drives, we recommend that you set this field to “Disabled” to save time.
Boot Up NumLock Status
Toggle between “On” or “Off” to control the state of the NumLock key when the
system boots. When toggled “On”, the numeric keypad generates numbers instead of
controlling cursor operations.
Typematic Rate Setting
When “Disabled”, the following two items, “Typematic Rate” and “Typematic Delay”,
are irrelevant. Keystrokes repeat at a rate determined by the keyboard controller in
your system. When “Enabled”, you can select a Typematic Rate and Typematic Delay.
Typematic Rate (Chars/Sec)
When the “Typematic Rate” setting is “Enabled”, you can select a Typematic Rate,
(the rate at which characters repeat when you hold down a key) of 6, 8, 10,12, 15, 20,
24 or 30 characters per second.
Typematic Delay (Msec)
When the “Typematic Rate” setting is “Enabled”, you can select a Typematic Delay,
(the delay before key strokes begin to repeat) of 250, 500, 750 or 1000 milliseconds.
Security Option
If you have set a password, select whether the password is required each time the
System boots, or only when you enter Setup.
PCI/VGA Palette Snoop
Some display cards that are not standard VGA, such as graphics accelerators or MPEG
cards, may not show the correct colors. This setting can correct the problem once it is
set it to “Enabled”. For default setting, leave at “Disabled”.
4. BIOS SETUP
OS select for DRAM > 64MB
Select “OS2” only if you are running OS/2 operating system with greater than 64 MB
of RAM on your system.
Shadow
This is software that resides in a Read-Only Memory, (ROM), chip on a device is
called “firmware”. The Award BIOS permits “shadowing” of firmware such as the
system BIOS, video BIOS, and similar operating instructions that come with some
expansion peripherals, such as, for example, a SCSI adaptor.
Shadowing copies firmware from ROM into system RAM, where the CPU can read it
through the 16-bit or 32-bit DRAM bus. Firmware not shadowed must be read by the
system through the 8-bit X-bus. Shadowing improves the performance of the system
BIOS and similar ROM firmware for expansion peripherals, but it also reduces the
amount of high memory (640 KB to 1 MB) available for loading device drivers, etc.
“Enable” shadowing into each section of memory separately. Many system designers
hard-wire shadowing of the system BIOS and eliminate a System BIOS Shadow option.
Video BIOS shadows into memory area C0000-C7FFF. The remaining areas shown on
the BIOS Features Setup screen may be occupied by other expansion card firmware. If
an expansion peripheral in your system contains ROM-based firmware, you need to
know the address range the ROM occupies to shadow it into the correct area of RAM.

4. BIOS SETUP
according to the type of IDE interface(s) installed in your system (PCI or ISA).
Standard ISA interrupts for IDE channels are IRQ14 for primary and IRQ15 for
secondary.
Primary/Secondary IDE INT#
Each PCI peripheral connection is capable of activating up to 4 interrupts: INT# A,
INT# B, INT# C and INT# D. By default, a PCI connection is assigned INT# A.
Assigning INT# B has no meaning unless the peripheral device requires two interrupt
services rather than just one. Because the PCI IDE interface in the chipset has 2
channels, it requires 2 interrupt services. The primary and secondary IDE INT# fields
default to values appropriate for 2 PCI IDE channels, with the primary PCI IDE
channel having a lower interrupt than the secondary.
