Using Your Mainboard – 2.3
CMOS Setup Utility Controls
Two sections of the CMOS Setup Utility allow you to config-
ure how some of your system’s features work. These are:
•
BIOS Features Setup
•
Power Management Setup
The CMOS Setup Utility is a program that is permanently
stored in the BIOS chip on the mainboard. The utility creates a
system hardware configuration record that it stores in a small
amount of battery-supported memory on the board. The BIOS
uses this record to function as an interface between the system
hardware and the operating system. Most of the settings in the
CMOS Setup Utility are made automatically, so you won’t nor-
mally need to use this program. You can, however, customize
some of the operational features to suit how you prefer to use
the system.
The screen illustrations on the next two pages show the Setup
Default settings for these two sections of the utility.
The CMOS Setup Utility Summary in Section 4: Reference
Information, lists the setting options for each section of the util-
ity including the two noted above.
