UEFI BIOS

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’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. 

⚠

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. 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.

Incompatible UEFI cases

∙

32-bit Windows operating system 

- this motherboard supports only Windows 10 

64-bit operating system.

∙

Older graphics card

 - the system will detect your graphics card. When display a 

warning message 

There is no GOP (Graphics Output protocol) support detected in 

this graphics card

.

⚠

Important

We recommend that you to use a GOP/ UEFI compatible graphics card.
