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 the CMOS RAM. Ask a qualified technician
for assistance.
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 the Aptio Setup Utility, make sure that you have saved
all open files. The system reboots immediately after you close the
Setup.
Notes: Aptio Setup Utility will be simply referred to as " Setup "
or " Setup utility " in this guide.
