UEFI BIOS

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 

capabilities. 

⚠

Important

The term BIOS in this user guide refers to UEFI BIOS unless otherwise noted.

UEFI advantages

∙

Fast booting - UEFI can directly boot the operating system and save the BIOS self-

test process. It can also eliminate 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.

Incompatible UEFI cases

∙

32-bit Windows operating system

 - this motherboard supports only Windows 10/ 

Windows 11 64-bit operating system.

∙

Older graphics card

 - the system will detect your graphics card. If you use older 

graphics cards, it may display a warning message 

There is no GOP (Graphics Output 

protocol) support detected in this graphics card

.

⚠

Important

We recommend that you replace it with a graphics card supporting GOP/UEFI or use 

CPU with integrated graphics for having normal function.
