What is UEFI BIOS
Note: The operating system settings might override any similar settings in 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 BIOS passwords, enter the correct passwords when prompted. You also can select No
or press Esc to skip the password prompt and enter the BIOS menu. However, you cannot change the
system configurations that are protected by passwords.

configurations might cause unexpected results.
