Date/Time
Set the date and time of the system.
IDE (Primary/Secondary; Master/Slave)
This category identifies up to four IDE hard disk drives that have been installed in the
computer. This section does not show information on other IDE devices such as
CD-ROM drives or other hard drive type such as SCSI drives.
Drive A
Select different Floppy device Model. Available options are [None], [360K, 5-1/4 in],
[1.2M, 5-1/4 in], [720k, 3-1/2 in], [1.44M, 3-1/2 in], and [2.88M, 3-1/2 in].
Video
Select the type of video adapter present in your system. You can ignore this setting
if you are using a VGA monitor since VGA BIOS automatically configures this setting.
Halt On
When the system is powered on, BIOS performs a series of diagnostic tests called
POST (Power On Self Test). This function stops the computer if BIOS detects a
hardware error. You can tell BIOS to halt on all errors, no errors, or not to halt on
specific errors.
3-2 Advanced BIOS Features
By choosing the Advanced BIOS Features option from the CMOS Setup Utility menu
(Figure 3-1), the screen below is displayed. This sample screen contains the
manufacturer's default values for the motherboard.

Virus Warning
When you set as enabled, you receive a warning message if a program
(specifically, a virus) attempts to write to the boot sector or the partition table
of the hard disk drive.
NOTE:
Many disk diagnostic programs that access the boot sector table can trigger
the virus-warning message. If you plan to run such a program, we recommend
that you first disable the virus warning.

CPU Internal Cache/External Cache
Cache memory is much faster than conventional DRAM system memory.
Chapter 3

These fields allow you to enable or disable the CPUs Level 1 built-in cache
and Level 2 external cache. Both settings are left enabled to significantly
increase the performance of your computer.

CPU L2 Cache ECC Checking
Enable this function for the CPU L2 Cache Error Checking and Correcting
(ECC) operation.

Quick Power On Self Test (POST)
Enable this function to reduce the amount of time required to run the POST
(Power On Self Test). BIOS will save time by skipping some items during
POST. It is recommended that you disable this setting. Discovering a
problem during boot up is better than loosing data during your work.

First/Second/Third/Boot Other Device
This option sets the sequence of drives BIOS attempts to boot from after
POST completes. BIOS will search these drives for an operating system.

Boot Up Floppy Seek
This is a set up check for floppy power-on after starting the computer
system.

Boot Up NumLock Status
This function defines the keyboard's number pad as number keys or arrow
keys. If it is set at on the number keys will be activated, if it is set at off the
arrow keys will be activated.

Keyboard Interface
Typematic Rate Setting
When enabled, you can set the following two-typematic control items.
When disabled, the keyboard controller determines keystrokes arbitrarily in
your system.
Typematic Rate (Chars/Sec)
The typematic rate sets the rate at which characters on the screen repeat
when a key is pressed and held down.
Typematic Delay (Msec)
The typematic delay sets how long after you press a key that a character
begins repeating.
( 9 ) Security Option
The Supervisor and/or User Password functions shown in Figure 3-1 must
be set to take advantage of this function. See Section 3.11 for password
setting information. When the Security Option is set to System, a password
must be entered to boot the system or enter the BIOS setup program. When
the Security Option is set to Setup, a password is required to enter the BIOS
setup program.
(10) APIC Mode
This item can enable or disable the APIC (
Advanced Programmable
Interrupt Controller
). Due to compliance to PC2001 design guide, the
system is able to run in APIC mode. Enabling APIC mode will expand
available IRQs resources for the system. Available options are [
Enabled
] and
[
Disabled
].
(11) MPS Version Control OS:
This item allows you to select which MPS (
Multi-Processor Specification
)
version to be used for the operating system. You need to select the MPS
version which is supported by your operating system. To find out which
version to use, consult the vendor of your operating system. Available options
