CHAPTER
4
BIOS Setup
The Award CMOS Setup Utility of your system is discussed in this chapter.
Basic Input and Output System (BIOS) is the interface between the hardware and the
operating system software. Its function is to provide a series of software interrupts
and functions that control operations on certain devices connected to your system.
Aside from this, it performs a series of Power On Self Test (POST) every time you boot
the system. POST checks your actual system configuration with the system
configuration data stored in a non-volatile memory known as CMOS RAM. These tests
are to ensure that your system is properly configured to recognize the devices such as
memory, HDD, etc.
Usually, you may need to perform setup due to the following circumstances:
%"
Setting the built-in clock/calendar to the correct time and/or date
%"
Enabling or disabling special features such as power management functions,
system passwords, etc.
%"
Setting or resetting configuration data if these were accidentally lost or if the
onboard battery was replaced.
REMARK Setup menus are subject to change without prior notice.
