3.1 Knowing BIOS
The new ASUS UEFI BIOS is a Uni ed Extensible Interface that complies with UEFI
architecture, offering a user-friendly interface that goes beyond the traditional keyboard-
only BIOS controls to enable a more exible and convenient mouse input. You can easily
navigate the new UEFI BIOS with the same smoothness as your operating system. The
term BIOS in this user manual refers to UEFI BIOS unless otherwise speci ed.
BIOS (Basic Input and Output System) stores system hardware settings such as storage
device con guration, overclocking settings, advanced power management, and boot
device con guration that are needed for system startup in the motherboard CMOS. 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.
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
.
When downloading or updating the BIOS le, rename it as
Z270SG.CAP
for this
motherboard.
