CMOS Setup Utility
The CMOS Setup Utility is a program for configuring the BIOS settings for the
main components of your computer.
Your system ships from the factory with the correct system parameters for your
configuration. Unless you add optional hardware, you do not need to run the
CMOS Setup Utility to operate your system. However, you might wish to run
the Setup utility to set features that customize your system, such as power
management and security features.
System configuration information is stored in nonvolatile memory. A
nonvolatile memory device retains its data when system power is turned off.
Nonvolatile memory in your system is stored in a complementary metal-oxide
semiconductor (CMOS) chip backed up by a battery on the system board. The
battery supplies continuous power to CMOS memory and maintains
configuration information when system power is off.
NEC CSD recommends that you print out or write down your current CMOS
Setup parameters and store the information in a safe place. This lets you restore
your system to the current parameters if you ever need to replace the battery.
When to Use CMOS Setup
The BIOS Setup utility is used to view and set parameters. Use the Setup utility
to:
T
set the time and date
T
update or check parameters when adding or removing expansion options
T
change or set power management features
T
correct a hardware discrepancy when the Power-On Self-Test (POST)
displays an error message and prompts to run Setup
