3.1 Standard CMOS Setup
The Standard CMOS Setup allows users to configure system components
such as hard disk drive, floppy disk drive and video display as well as date, time
and boot-up error signaling. This configuration menu should be changed when
installing a motherboard for the first time, changing hardware in your system
such as the HDD, FDD, video display, or when the CMOS data has been lost or
contaminated. Choose the Standard CMOS Setup option from the CMOS Setup
Utility menu (Figure 3-1) to display the following screen.
Figure 3-2
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/B:
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.
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.
