UEFI BIOS

This section introduces what is UEFI BIOS and the operations you can perform in UEFI BIOS.

What is UEFI BIOS

UEFI BIOS is the first program that the computer runs when the computer is turned on. UEFI BIOS initializes
the hardware components and loads the operating system and other programs. Your computer comes with a
setup program with which you can change UEFI BIOS settings.

Note: If you have set the supervisor password, enter the correct password when prompted. You also can
press Enter to skip the password prompt and enter the UEFI BIOS menu. However, you cannot change the
system configurations that are protected by the supervisor password.
