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. These changes are
implemented to further enhance system
performance.
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.

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. We recommend you to use the Optimal settings if your system has
large memory size and fully loaded with add-on card (for example, a file
server using double-sided 8MB SIMM x4 and SCSI plus Network card
occupying the PCI and ISA slots).
Optimal is not the slowest setting for this mainboard. If you need to verify a
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 Optimal
values. However, Turbo values may not be the best setting of this mainboard
but these values are qualified by the AOpen RD and QA department as the
reliable settings especially if you have limited loading of add-on card and
memory size (for example, a system that contains only a VGA/Sound card
and two SIMMs).
To attain the best system performance, you may manually set the parameters
in the "Chipset Features Setup" to get proprietary setting. Make sure that you
know and understand the functions of every item in Chipset Setup menu. The
performance difference of Turbo from Optimal is normally around 3% to 10%,
depending on the chipset and the application.

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 auto-detected 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.
