The primary function of the BIOS (Basic Input and Output System) is to identify and initiate component
hardware. The BIOS parameters are stored in non-volatile BIOS memory (CMOS). CMOS contents don’t get
erased when the computer is turned off. The following topics are described in this chapter.

Using BIOS
When you start the Setup Utility, the main menu appears. The main menu of the Setup Utility displays a list
of the options that are available. A highlight indicates which option is currently selected. Use the cursor arrow
keys to move the highlight to other options. When an option is highlighted, execute the option by pressing
<Enter>.
Some options lead to pop-up dialog boxes that prompt you to verify that you wish to execute that option.
Other options lead to dialog boxes that prompt you for information.
Some options (marked with a triangle ►) lead to submenus that enable you to change the values for the
option. Use the cursor arrow keys to scroll through the items in the submenu.

Standard CMOS Features
Selecting Standard CMOS Features on the main menu displays the following menu:
Date and Time
The Date and Time items show the current date and time held by the machine. If you are running a Windows
OS, these items are automatically updated whenever you make changes to the Windows Date and Time
Properties utility.
Video
These elds is used to select the default video device. The default setting is EGA/VGA.
Halt On
This item denes the operation of the system POST (Power On Self Test) routine. You can use this item to
select which types of errors in the POST are sufcient to halt the system.
Base Memory, Extended Memory, and Total Memory
These items are automatically detected by the system at start up time. These are display-only elds. You
cannot make changes to these elds.
Base Memory – This eld displays the amount of conventional memory detected by the system during •
boot.
Extended Memory – This eld displays the amount of extended memory detected by the system dur-•
ing boot.
Total Memory – This eld displays the total amount of memory (Base and Extended) detected by the •
system during boot.

IDE Channel 0/2/3 Master/Slave
These elds are used to congure the IDE hard drives. Move the cursor to highlight the elds and press
<Enter> to enter the submenus.
IDE HDD Auto-Detection
Press Enter while this item is highlighted if you want the Setup Utility to automatically detect and congure
a hard disk drive on the IDE channel. (Note: If you are setting up a new hard disk drive that supports LBA
mode, more than one line will appear in the parameter box. Choose the line that lists LBA for an LBA drive.)
IDE Channel 0/2/3 Master/Slave
If you leave this item at Auto, the system will automatically detect and congure any IDE devices it nds. If
it fails to nd a hard disk, change the value to Manual and then manually congure the drive by entering the
characteristics of the drive in the elds described below:
Capacity – displays the capacity of the HDD in megabytes (MB).•
Cylinder – indicates the number of cylinders that the HDD has. A cylinder is the sum total of all tracks•
that are in the same location on every disk surface.
Head – displays the number of heads in the HDD. A head is a device that reads and writes data on the•
hard disk.
Precomp – displays the track where precompensation is initiated. Precompensation is a feature•
whereby the HDD uses a stronger magnetic eld to write data in sectors that are closer to the center
of the disk. In CAV recording, in which the disk spins at a constant speed, the sectors closest to the
spindle are packed tighter than the outer sectors.
Landing Zone – displays the location of the safe non-data area on a hard disk that is used for parking•
the read/write head.
Sector – displays the number of sectors available on the HDD. A sector is the smallest unit of storage•
space on a disk.
Access Mode
This item denes special ways that can be used to access IDE hard disks such as LBA (Large Block
Addressing). Leave this value at Auto and the system will automatically decide the fastest way to access the
hard disk drive.

Advanced BIOS Features
Selecting Advanced BIOS Features on the main menu opens up this screen:
Virus Warning
When enabled, this item provides protection against viruses that try to write to the boot sector and partition
table of the hard disk drive. You need to disable this item when installing an operating system. We recommend
that you enable anti-virus protection as soon as you have installed an operating system. The default setting is
Disabled.
First/Second/Third Boot Device
The BIOS loads the operating system from the disk drives in the sequence selected in these three elds. The
default setting is USB-ZIP/USB-CDROM/Hard Disk.
Boot Other Device
When enabled, the system searches all other possible locations for an operating system if it fails to nd one in
the devices specied under the First, Second, and Third boot devices. The default setting is Enabled.
Boot Up NumLock Status
This eld is used to select power on state for NumLock. The default setting is On.
Gate A20 Option
Select this item if chipset or keyboard controller should control GateA20. Select Normal, a pin in the
keyboard controller controls GateA20. Select Fast, lets chipset control GateA20. The default setting is Fast.
Typematic Rate Setting
Key strokes repeat at a rate determined by the keyboard controller. When enabled, the typematic rate and
typematic delay can be selected. The default setting is Disabled.
Typematic Rate (Chars/Sec)
This eld is used to set the number of times a second to repeat a key stroke when you hold the key down. The
default setting is 6.
Typematic Delay (Msec)
This eld is used to set the delay time after the key is held down before it begins to repeat the keystroke. The
default setting is 250.

Select whether the password is required every time the system boots or only when you enter setup. The
default setting is Setup.
Option Description
System The system will not boot and access to Setup will be denied if the correct password is not

APIC Mode
This item is used to activate the ACPI (Advanced Conguration and Power Management Interface) Mode.
The default setting is Enabled.
IMPORTANT
ACPI is a power management specication that makes hardware
status information available to the operating system. ACPI enables a
PC to turn its peripherals on and off for improved power management.
It also allows the PC to be turned on and off by external devices, so
that mouse or keyboard activity wakes up the machine.
