Bios Setup Utility; When To Use Bios Setup - NEC POWERMATE PROFESSIONAL 9000 Service Manual

THE BIOS SETUP UTILITY
The BIOS Setup utility program is used to configure the main components of the computer.
System configuration information is stored in nonvolatile memory. A nonvolatile memory
device retains its data when system power is turned off. Nonvolatile memory in the 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 (see "Replacing the Battery"
in Chapter 8).

When to Use BIOS Setup

The BIOS Setup utility lets you view and set system parameters. Use Setup to:
T
set the time and date.
T
update or check system parameters when you add or remove 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 you to run Setup.
NOTE: The system ships from the factory with
the correct system parameters for the
configuration. Unless you add optional hardware
(or disable the password), you do not need to run
the BIOS Setup utility to operate the system.
However, you might wish to run the Setup utility
to set features that customize the system, such as
security features.
NOTE: NECCSD recommends that you print
out or write down the current BIOS Setup
parameters and store the information in a safe
place. This will enable you to restore the system
to the current parameters if you ever need to
replace the battery or enter Maintenance Mode.
