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.
