This chapter describes the Setup utility program that allows
you to enter system configuration information and control
special features of the system.
The chapter also contains information about updating
the BIOS in your system, setting mouse parameters for
MS-DOS, selecting video modes, and using the NEC
Bulletin Board Service. The chapter includes information
about network drivers and network interface board settings
for network-ready systems.
NOTE
Your system ships from the factory with
the correct system parameters for your configura-
tion. Unless you add optional hardware, you do not
need to run Setup to operate your system.
However, you might wish to run the Setup utility to
set features that customize your system, such as
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 Chapter 7).
