4-2 Configuring the System
Your NEC Direction SP B-Series computer system is made
up of many different components that work together to keep
the system operating normally. This chapter provides
information on the NEC CSD utilities available for your
system.
System BIOS and the Setup Utility
Configuration information is stored in a nonvolatile memory
chip, a device that retains its data when system power is
turned off. This chip is called a complementary metal-oxide
semiconductor (CMOS) chip, and it is 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.
The system BIOS (Basic Input/Output System) is a set of
configuration instructions burned into the CMOS chip. Your
system ships from the factory with the BIOS set correctly for
your configuration. Unless you add optional hardware, you
do not need to run the Setup utility to operate your system.
However, you might wish to run Setup to set features that
customize your system, such as to add or adjust security
features.
Setup Utility
The Setup utility program allows you to enter system
configuration information in the BIOS and control special
features of the system.
