BIOS overview

BIOS setup is a hardware configuration program built into the 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 settings.
• When redefining the communication ports to prevent any conflicts.
• When modifying the power management configuration.
• When changing the password or making other changes to the security
setup.
• 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.
BIOS setup loads the configuration values in a battery-backed non-volatile
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 the BIOS Setup Utility, make sure that you have saved all
open files. The system reboots immediately after you close the Setup.
