2-20 Setup and Operation
SETUP UTILITY
The Setup utility program allows you to enter system configuration information and control
special features of the system.
NOTE: System ships from the factory with the
correct system parameters for the configuration.
Unless adding optional hardware, run the Setup
utility only to customize the system, such as
setting the 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 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 CMOS Battery” in
Section 4).
NOTE:
NEC recommends that you print out or
write down your current 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 Setup
The Setup utility lets you view and set system parameters. Use the Setup utility program:
n
to set the time and date.
n
to update or check system parameters when you add or remove expansion
options.
n
to change or set power management features.
n
to correct a hardware discrepancy when the Power-On Self-Test (POST) displays
an error message and prompts you to run Setup.
n
to check the installation of optional memory by comparing the amount of memory
installed with the amount of memory displayed by Setup.
n
to change certain system operating parameters, such as boot device sequence and
keyboard parameters.
