Introducing BIOS
The BIOS is a program located on a Flash Memory on the motherboard. This program
is a bridge between motherboard and operating system. When you start the computer,
the BIOS program will gain control. The BIOS first operates an auto-diagnostic test
called POST (power on self test) for all the necessary hardware, it detects the entire
hardware device and configures the parameters of the hardware synchronization.
Only when these tasks are completed done it gives up control of the computer to
operating system (OS). Since the BIOS is the only channel for hardware and software
to communicate, it is the key factor for system stability, and in ensuring that your
system performance as its best.
In the BIOS Setup main menu of Figure 3-1, you can see several options. We will
explain these options step by step in the following pages of this chapter, but let us first
see a short description of the function keys you may use here:
•
Press <Esc> to quit the BIOS Setup.
•
Press ↑↓←→ (up, down, left, right) to choose, in the main menu, the option you
want to confirm or to modify.
•
Press <F10> when you have completed the setup of BIOS parameters to save
these parameters and to exit the BIOS Setup menu.
•
Press Page Up/Page Down or +/– keys when you want to modify the BIOS
parameters for the active option.

3-1 Entering Setup
Power on the computer and by pressing <Del> immediately allows you to enter Setup.
If the message disappears before your respond and you still wish to enter Setup,
restart the system to try again by turning it OFF then ON or pressing the “RESET”
button on the system case. You may also restart by simultaneously pressing <Ctrl>,
<Alt> and <Delete> keys. If you do not press the keys at the correct time and the
system does not boot, an error message will be displayed and you will again be asked
to
Press <Del> to enter Setup

3-12 BIOS Security Features
You can set either supervisor or user password or both of them. The differences
are:
Supervisor password: Can enter and change the options of the setup menus.
User password: Can only enter but do not have the right to change the options of
the setup menus. 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 the password up to eight characters in length, and press <Enter>. The
password typed now will clear any previously entered password from CMOS
34
memory. You will be asked to confirm the password. Type the password again
and press <Enter>. You may also press <Esc> to abort the selection and not enter
a password.
To disable a password, just press <Enter> when you are prompted to enter the
password. A message will confirm that the password will be disabled. Once the
password is disabled, the system will boot and you can enter Setup freely.
PASSWORD DISABLED
When a password has been enabled, you will be prompted to enter it every time
you try to enter Setup. This prevents an unauthorized person from changing any
part of your system configuration.
Additionally, when a password is enabled, you can also require the BIOS to
request a password every time your system is rebooted. This would prevent
unauthorized use of your computer.
You determine when the password is required within the BIOS Features Setup
Menu and its Security option. If the Security option is set to “System”, the
password will be required both at boot and at entry to Setup. If set to “Setup”,
prompting only occurs when trying to enter Setup.
Boot Sector Virus Protection
The selection allows you to choose the VIRUS Warning feature for IDE Hard Disk
boot sector protection. If this function is enabled and someone attempt to write
data into this area, BIOS will show a warning message on screen and alarm beep.
Disabled (default) No warning message to appear when anything attempts to
access the boot sector or hard disk partition table.
Enabled Activates automatically when the system boots up causing a warning
message to appear when anything attempts to access the boot sector of hard disk
partition table.

When you press <Enter> on this item, you get a confirmation dialog box with a
message similar to:
Pressing <OK> loads the default values that are factory settings for optimal
performance system operations.
Load Standard Defaults
When you press <Enter> on this item, you get a confirmation dialog box with a
message similar to:
Pressing <OK> loads the default values that are factory settings for stable
performance system operations.
36
3-14 Save Changes and Exit / Discard Changes and Exit
Save Changes and Exit
When you press <Enter> on this item, you get a confirmation dialog box with a
message similar to:
Pressing <OK> save the values you made previously and exit BIOS setup.
Discard Changes and Exit Setup?
When you press <Enter> on this item, you get a confirmation dialog box with a
message similar to:
Pressing <OK> to leave BIOS setting without saving previously set values.
Notice! The BIOS options in this manual are for reference only. Different
configurations may lead to difference in BIOS screen and BIOS
screens in manuals are usually the first BIOS version when the board is
released and may be different from your purchased motherboard.
Users are welcome to download the latest BIOS version form our
official website.
