Chapter 4: Recovering your system Entering the BIOS Setup BIOS (Basic Input and Output System) stores system hardware settings that are needed for system startup in the ASUS All-in-One 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. Quickly enter the BIOS To access the BIOS: • When your ASUS All-in-One PC is off, press the power button for at least four (4) seconds to access the BIOS directly. • Press the power button to turn on your ASUS All-in-One PC then press or during POST. NOTE: POST (Power-On Self-Test) is a series of software controlled diagnostic tests that run when you turn on your ASUS All-in-One PC. ASUS All-in-One PC ET223 and ET203 57
