BIOS Setup
System BIOS
BIOS (Basic Input and Output System) records hardware parameters of the system in the EFI on the
motherboard. Its major functions include conducting the Power-On Self-Test (POST) during system startup,
saving system parameters, loading the operating system etc. The BIOS includes a BIOS Setup program that
allows the user to modify basic system configuration settings or to activate certain system features. When the
power is turned off, the battery on the motherboard supplies the necessary power to the CMOS to keep the
configuration values in the CMOS.
To access the BIOS Setup program, press the <DEL> key during the POST when the power is turned on.
