ESD Precautions
Computer boards have integrated circuits sensitive to static electricity. To prevent chipsets from electrostatic discharge damage, please take care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
Before holding the board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. It discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

CHAPTER 4
PHOENIX-AWARD BIOS UTILITY
The Phoenix-Award BIOS provides users with a built-in Setup program to modify basic system configuration. All configured parame ters are stored in a battery-backed-up RAM (CMOS RAM) to save the Setup information whenever the power is turned off.
4.1 Entering Setup
There are two ways to enter the Setup program. You may either turn ON the computer and press <Del> immediately, or press the <Del> and/or <Ctrl>, <Alt>, and <Esc> keys simultaneously when the following message appears at the bottom of the screen during POST (Power on Self Test).
TO ENTER SETUP PRESS DEL KEY
If the message disappears before you respond and you still want to enter Setup, please restart the system to try it again. Turning the system power OFF and ON, pressing the “RESET” button on the system case or simultaneously pressing <Ctrl>, <Alt>, and <Del> keys can restart the system. If you do not press keys at the right time and the system doesn’t boot, an error message will pop out to prompt you the following information:
PRESS <F1> TO CONTINUE, <CTRL-ALT-ESC> OR <DEL> TO ENTER SETUP

4.4 The Main Menu
Once you enter the Award BIOS CMOS Setup Utility, the Main Menu appears on the screen. In the Main Menu, there are several Setup functions and a couple of Exit options for your selection. Use arrow keys to select the Setup Page you intend to configure then press <Enter> to accept or enter its sub-menu.
NOTE If your computer can not boot after making and saving
system changes with Setup, the Award BIOS will reset your system to the CMOS default settings via its built-in override feature.
It is strongly recommended that you should avoid changing the chipset’s defaults. Both Award and your system manufacturer have carefully set up these defaults that provide the best perfo rma nce an d reliability.

The categories identify the types of one channel that have been installed in the computer. There are 45 predefined types and 2 users definable types are for Enhanced IDE BIOS. Type 1 to Type 45 is predefined. Type User is user-definable. Press <PgUp>/<+> or <PgDn>/<> to select a numbered hard disk type or type the number and press <Enter>. Note that the specifications of your drive must match with the drive table. The hard disk will not work properly if you enter improper information within this category. If your hard disk drive type does not match or is not listed, you can use Type User to define your own drive type manually. If you select Type User, related information is asked to be entered to the following items. Enter the information directly from the keyboard and press <Enter>. This information should be provided in the documentation from your hard disk vendor or the system manufacturer. If the controller of HDD interface is ESDI, select “Type 1”.

z IRQ Resources
When resources are controlled manually, assign each system interrupt as one of the following types, depending on the type of device using the interrupt:
1. Legacy ISA Devices compliant with the original PC AT bus specification, requiring a specific interrupt (such as IRQ4 for serial port
1).
2. PCI/ISA PnP Devices compliant with the Plug and Play standard, whether designed for PCI or ISA bus architecture.
The default value is “PCI/ISA PnP”.
z DMA Resources
When resources are controlled manually, assign each system DMA channel as one of the following types, depending on the type of device using the interrupt:
1. Legacy ISA Devices compliant with the original PC AT bus specification, requiring a specific DMA channel.
2. PCI/ISA PnP Devices compliant with the Plug and Play standard, whether designed for PCI or ISA bus architecture.
The default value is “PCI/ISA PnP”.
z PCI/VGA Palette Snoop
Some non-standard VGA display cards may not show colors properly. This field allows you to set whether MPEG ISA/VESA VGA Cards can work with PCI/VGA or not. When enabled, a PCI/VGA can work with a MPEG ISA/VESA VGA card. When disabled, a PCI/VGA cannot work with a MPEG ISA/VESA Card.
z Assign IRQ For VGA

the options on the setup menu.
When you select this function, the following message will appear at the center of the screen to assist you in creating a password.
ENTER PASSWORD
Type a maximum eight-character password, and press <Enter>. This typed password will clear previously entered password from the CMOS memory. You will be asked to confirm this password. Type this password again and press <Enter>. You may also press <Esc> to abort this selection and not enter a password.
To disable the password, just press <Enter> when you are prompted to enter a password. A message will confirm the password is getting disabled. Once the password is disabled, the system will boot and you can enter Setup freely.
PASSWORD DISABLED
When a password is enabled, you have to type it every time you enter the Setup. It prevents any unauthorized persons from changing your system configuration.
Additionally, when a password is enabled, you can also require the BIOS to request a password every time the system reboots. This would prevent unauthorized use of your computer.
You decide when the password is required for the BIOS Features Setup Menu and its Security option. If the Security option is set to “System”, the password is required during booting up and entry into the Setup; if it is set as “Setup”, a prompt will only appear before entering the Setup.
