58 4 System BIOS 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 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 PhoenixBIOS Setup Utility, make sure that you have saved all open files. The system reboots immediately after you close the Setup. Note: PhoenixBIOS Setup Utility will be simply referred to as "Setup" or "Setup Utility" in this guide. The screenshots used in this guide display default system values. These values may not be the same those found in your system.

4 System BIOS

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
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
Phoenix
BIOS Setup Utility, make sure that you have
saved all open files. The system reboots immediately after you close the
Setup.
Note:
Phoenix
BIOS Setup Utility will be simply referred to as
"
Setup
"
or
"
Setup Utility
"
in this guide.
The screenshots used in this guide display default system values.
These values may not be the same those found in your system.
