4.1 Managing and updating your BIOS
BIOS (Basic Input and Output System) stores system settings such as storage device
conguration, overclocking settings, advanced power management, and boot device
conguration that are needed for system startup in the motherboard CMOS. In normal
circumstances, the default BIOS settings provide optimum performance in most operating
conditions. DO NOT change the default BIOS settings except in the following circumstances:
• An error message appears on the screen during the system startup and requests you
to run the BIOS setup.
• You have installed a new system component that requires further BIOS settings or
update.
• Incorrect BIOS settings may result to system instability or boot failure. We strongly
recommend that you change the BIOS settings with the help of trained service
personnel.
• Updating the BIOS is potentially risky. If there are no issues using the current BIOS
version, DO NOT manually update the BIOS. A failed BIOS update may result in
system boot failure.
