MSI UEFI BIOS is compatible with UEFI (Unified Extensible Firmware Interface)
architecture. UEFI has many new functions and advantages that traditional BIOS
cannot achieve, and it will completely replace BIOS in the future. The MSI UEFI
BIOS uses UEFI as the default boot mode to take full advantage of the new chipset’s
capabilities. However, it still has a CSM (Compatibility Support Module) mode to be
compatible with older devices. That allows you to replace legacy devices with UEFI
compatible devices during the transition.

The term BIOS in this user guide refers to UEFI BIOS unless otherwise noted.

Fast booting - UEFI can directly boot the operating system and save the BIOS self-
test process. And also eliminates the time to switch to CSM mode during POST.
Supports for hard drive partitions larger than 2 TB.
Supports more than 4 primary partitions with a GUID Partition Table (GPT).
Supports unlimited number of partitions.
Supports full capabilities of new devices - new devices may not provide backward
compatibility.
Supports secure startup - UEFI can check the validity of the operating system to
ensure that no malware tampers with the startup process.
