Chapter 3
Award BIOS
This chapter tells how to configure the system parameters. You may update
your BIOS via AWARD Flash Utility.
Important: Because the BIOS code is the most
often changed part of the mainboard design, the
BIOS information contained in this chapter
(especially the Chipset Setup parameters) may be
a little different compared to the actual BIOS that
came with your mainboard.

3.1 Entering the Award BIOS Setup Menu
The BIOS setup utility is a segment of codes/routines residing in the BIOS
Flash ROM. This routine allows you to configure the system parameters and
save the configuration into the 128 byte CMOS area, (normally in the RTC chip
or directly in the main chipset). To enter the BIOS Setup, press during
POST (Power-On Self Test). The BIOS Setup Main Menu appears as follows.
Tip: Choose "Load Setup Defaults" for
recommended optimal performance. Choose
"Load Turbo Defaults" for best performance
with light system loading. Refer to section 3.7.
The section at the bottom of the screen tells how to control the screen. Use the
arrow keys to move between items, F9 to change language, ESC to exit, and
F10 to save the changes before exiting. Another section at the bottom of the
screen displays a brief description of the highlighted item.
After selecting an item, press Enter to select or enter a submenu.

3.2 Standard CMOS Setup
The "Standard CMOS Setup" sets the basic system parameters such as the
date, time, and the hard disk type. Use the arrow keys to highlight an item and
or to select the value for each item.
Standard CMOS à Date
To set the date, highlight the Date parameter. Press or to set the
current date. The date format is month, date, and year.

Number of Sector per Track. The default setting is Auto,
which enables BIOS to automatically detect the parameters
of installed HDD (Hard Disk Drive) at POST (Power-On Self
Test). If you prefer to enter HDD parameters manually,
select User. Select None if no HDD is connected to the
system.
The IDE CDROM is always automatically detected.
Tip: For an IDE hard disk, we recommend that
you use the "IDE HDD Auto Detection" to enter
the drive specifications automatically. See the
section "IDE HDD Auto Detection".

possible through the Logical Block Address (LBA) mode
translation. The LBA is now considered a standard feature
of current IDE hard disk on the market because of its
capability to support capacity larger than 528MB. Note that
if a HDD is formatted with LBA On, it will not be able to boot
with LBA Off.

specify the delay of 8-bit I/O command by count of
ISA bus clock. If you find any unstable 8-bit I/O card,
you may try to extend the I/O recovery time via this

Clock Throttling means at the Doze/Standby state,
the CPU clock count in a given time (not the
frequency) is reduced to the ratio specified in this
parameter. Actually, the period per CPU clock is not
changed. For example, a 66MHz CPU clock remains
the same 30ns clock period when system goes into
Doze/Suspend. The chipset generates the STPCLK
(stop clock) signal periodically to prevent CPU for
accepting clock from clock generator. For full power
on, the CPU can receive 66M count in one second. If
the Slow Clock Ratio is set to 50%, the CPU will only
receive 33M clock count in one second. This will
effectively reduce CPU speed as well as CPU power.

3.7 Load Setup Defaults
The "Load Setup Defaults" option loads optimized settings for optimum system
performance. Optimal settings are relatively safer than the Turbo settings. All
the product verification, compatibility/reliability test report and manufacture
quality control are based on "Load Setup Defaults". We recommend you to use
this settings for normal operation. "Load Setup Defaults" is not the slowest
setting for this motherboard. If you need to verify an unstable problem, you
may manually set the parameter in the "BIOS Features Setup" and "Chipset
Features Setup" to get slowest and safer setting.
3.8 Load Turbo Defaults
The "Load Turbo Defaults" option gives better performance than "Load Setup
Defaults". It is provided for the convenience of power user who wants to push
the motherboard to get better performance. Turbo setting does not go though
all the detail reliability and compatibility test, it is tested only with limited
configuration and loading (for example, a system that contains only a VGA card
and two DIMMs). Use Turbo setting only when you fully understand the items in
Chipset Setup menu. The performance improvement of Turbo setting is
normally around 3% to 5%, depending on the chipset and the application.

A traditional ATX system should remain at power off
stage when AC power resumes from power failure.
This design is inconvenient for a network server or
workstation, without an UPS, that needs to keep

Selecting On lets the system can automatically
power-on after AC power resumes; in the other hand,
the system will power-off if you select Off. If FormerSts option is selected, the system will power-on or
power-off based on the original state.

3.10 Password Setting
Password prevents unauthorized use of your computer. If you set a password,
the system prompts for the correct password before boot or access to Setup.
To set a password:
1. At the prompt, type your password. Your password can be up to 8
alphanumeric characters. When you type the characters, they appear as
asterisks on the password screen box.
2. After typing the password, press.
3. At the next prompt, re-type your password and press again to confirm the
new password. After the password entry, the screen automatically reverts
to the main screen.
To disable the password, press when prompted to enter the password. The
screen displays a message confirming that the password has been disabled.
3.11 IDE HDD Auto Detection
If your system has an IDE hard drive, you can use this function to detect its
parameters and enter them into the "Standard CMOS Setup" automatically.
This routine only detects one set of parameters for your IDE hard drive. Some
IDE drives can use more than one set of parameters. If your hard disk is
formatted using different parameters than those detected, you have to enter the
parameters manually. If the parameters listed do not match the ones used to
format the disk, the information on that disk will not be accessible. If the autodetected parameters displayed do not match those that used for your drive,
ignore them. Type N to reject the values and enter the correct ones manually
from the Standard CMOS Setup screen.

“Save EEPROM Default” before choosing this command, otherwise, the system
is likely to boot improperly.
3.14 Save EEPROM Default
You may use this item to save your own settings into EEPROM. Then, if the
data in CMOS is lost or you forget the previous settings, you may use "Load
EEPROM Default " to reload.

not use this option if you want to save the new configuration.
3.16 NCR SCSI BIOS and Drivers
The NCR 53C810 SCSI BIOS resides in the same flash memory chip as the

The NCR SCSI BIOS directly supports DOS, Windows 3.1 and OS/2. For
better system performance, you may use the drivers that come with the NCR
SCSI card or with your operating system. For details, refer to the installation
manual of your NCR 53C810 SCSI card.

3.17 How to Upgrade the BIOS
AOpen Easy Flash is more user friendly than traditional flash method. The
BIOS binary file and flash routine are combined together and you simply run a
single file to complete the flash process.
1. Get new BIOS upgrade program from AOpen's web site. For example,
6BCEZ200.EXE. It is recommended to save it to a bootable DOS floppy
diskette for error recovery.
2. Reboot the system to DOS mode without loading any memory handler
(such as EMM386) or device driver. It needs around 520K free memory
space.
3. Execute A:> 6BCEZ200
DO NOT turn off the power during FLASH PROCESS.
4. Reboot the system by turn off the power after flash is completed.
5. Reload the "BIOS SETUP DEFAULT" and reconfigure other items as
previous set. Save & Exit. Done!
Note: If you encounter BIOS flash fail, use
PCI VGA card to check if it can be boot from
floppy and flash again.
3-40
Note: The upgrade of new BIOS will
permanently replace your original BIOS
content after flashing. The original BIOS
setting and Win95/Win98 PnP information will
be refreshed and you probably need to reconfigure your system.
