Revision History 69

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.

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 1164-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.

We recommend that you replace it with a graphics card supporting GOP/UEFI or use CPU with integrated graphics for having normal function.

How to find the BIOS version?

After entering the BIOS, find the BIOS version in the information box.

BIOS Setup

The default settings offer optimal performance for system stability in normal conditions. You should always keep the default settings to avoid possible system damage or failure booting unless you are familiar with BIOS.

- The BIOS setup screens, options, and settings in this manual are for reference only and may vary from the motherboard you purchased. Please refer to the actual BIOS version of your system for detailed screens, settings and options.

- In Advanced mode, you can find BIOS item descriptions at the bottom of the BIOS screen for information on the purpose and function of each BIOS setting. BIOS items are continuously updated for better system performance. Therefore, the description may differ slightly from the latest BIOS and should be for reference only.

Updating BIOS

Updating BIOS with M-FLASH

Before starting the M-Flash process, make sure you have:

- A USB flash drive with a capacity of 32GB or less that is formatted to FAT32.

M-Flash only supports FAT32 format, and the USB flash drive should not exceed 32GB.

- A computer with internet access.

Please follow the steps below to update BIOS:

1. Download the latest BIOS file from the MSI website that matches your motherboard model, and save it to the USB flash drive.
2. If your motherboard has a Multi-BIOS switch, switch to the target BIOS ROM.
3. Insert the USB flash drive into your motherboard's USB port.

4. Enter flash mode by either:

5. Rebooting and pressing Ctrl + F5 during POST, then clicking Yes to reboot the system.

6. Rebooting and pressing Del during POST to enter BIOS, then clicking the M-FLASH button and clicking Yes to reboot.

7. Select a BIOS file from the M-FLASH File menu and press Enter.

8. When prompted by a File Check message, click Yes to start the BIOS update.

Once the update reaches 100%, the system will reboot automatically.

Updating the BIOS with MSI Center

2. Rename the BIOS file to MSI.ROM, and save it to the root directory of a USB flash device.
3. Connect the power supply to CPU_PWR1 and ATX_PWR1. (You don't need to install the CPU and memory.)
4. Plug the USB flash device with the MSI.ROM file into the Flash BIOS Port on the rear I/O panel.
5. Press the Flash BIOS Button to start flashing the BIOS. The LED will start flashing to indicate the process has begun.
