BIOS setup BIOS setup is a hardware configuration program built into your
system's Basic Input/Output System (BIOS). Since most systems are
already properly configured and optimized, there is no need to run this
utility. You will need to run this utility under the following conditions:
• When changing the system configuration
• When a configuration error is detected by the system and you are
prompted ("Run Setup" message) to make changes to the BIOS
setup
Note: If you repeatedly receive Run Setup messages, the battery
may be bad. In this case, the system cannot retain configuration
values in CMOS. Ask a qualified technician for assistance.
• When redefining the communication ports to prevent any conflicts
• When making changes to the Power Management configuration
• When changing the password or making other changes to the
security setup
BIOS setup loads the configuration values in a battery-backed
nonvolatile memory called CMOS RAM. This memory area is not part
of the system RAM which allows configuration data to be retained
when power is turned off.
Before you run BIOS setup, make sure that you have saved all open
files. The system reboots immediately after you close the setup.
