BIOS (Basic Input and Output System) stores system hardware settings that are needed for 

system startup in the PC. 
In normal circumstances, the default BIOS settings apply to most conditions to ensure optimal 

performance. Do not change the default BIOS settings except in the following circumstances: 
•  An error message appears on the screen during the system bootup and requests you to run 

the BIOS Setup.

•  You have installed a new system component that requires further BIOS settings or update.

WARNING!  Inappropriate BIOS settings may result to instability or boot failure. We strongly 

recommend that you change the BIOS settings only with the help of a trained service personnel.
