How to Update the BIOS on an MSI B550M Pro-VDH Wi-Fi Motherboard

Updating the BIOS on your MSI B550M Pro-VDH Wi-Fi motherboard is a critical process that can improve system stability, compatibility with newer hardware, and even unlock performance enhancements. It’s generally recommended to update your BIOS if you are experiencing issues or need to support a new CPU or other components. The process involves downloading the latest BIOS version from MSI’s website, preparing a USB drive, and then using either the M-FLASH utility within the BIOS or the BIOS Flashback feature (if applicable) to flash the new BIOS. Always ensure you have a stable power supply during the entire process to prevent potential damage to your motherboard. Let’s delve deeper into each step.

Preparing for the BIOS Update

Before diving into the actual flashing process, careful preparation is paramount. This stage involves gathering the necessary resources and ensuring your system is ready for the update. Skipping this step can lead to frustrating errors or, worse, a bricked motherboard.

Identifying Your Current BIOS Version

Knowing your current BIOS version is crucial for determining if an update is necessary and for tracking changes after the update. There are several ways to find this information:

During Boot-Up: As your computer starts, you’ll often see a brief screen displaying the BIOS version. This is the quickest way to check. Pay close attention during the POST (Power-On Self-Test) screen.
System Information (Windows): In Windows, you can type “System Information” in the search bar and open the app. Look for the “BIOS Version/Date” entry.
MSI Center Software: If you have MSI Center installed, it often displays system information, including the BIOS version.

Downloading the Latest BIOS from MSI

Once you know your current BIOS version, head to the MSI website. Navigate to the support page for the B550M Pro-VDH Wi-Fi motherboard.

Search for your Motherboard: Use the search bar and type “B550M Pro-VDH Wi-Fi” to find your specific motherboard model.
Navigate to the Support Section: Look for a “Support” or “Download” tab.
Find the BIOS Section: Within the support section, you’ll find a “BIOS” category.
Download the Latest Version: Download the latest available BIOS file. MSI typically provides release notes detailing the changes and improvements in each version. Read these notes carefully to understand if the update addresses your specific needs or concerns.
Extract the BIOS File: The downloaded file is usually a compressed archive (ZIP or RAR). Extract the contents to a known location on your computer. You will find the actual BIOS file with a filename extension such as .ROM or .CAP.

Preparing the USB Drive

The next step involves preparing a USB drive that will be used to flash the BIOS.

USB Drive Requirements: You’ll need a USB 2.0 drive formatted with the FAT32 file system. While some newer BIOS versions may support USB 3.0 drives, USB 2.0 offers better compatibility and reduces the risk of errors.
Format the USB Drive: If your USB drive is not already formatted as FAT32, format it. Be aware that formatting will erase all data on the drive, so back up anything important first. In Windows, you can right-click on the drive in File Explorer, select “Format,” and choose FAT32 as the file system.
Copy the BIOS File: Copy the extracted BIOS file (the .ROM or .CAP file) to the root directory of the USB drive. Avoid creating any folders on the USB drive; the BIOS file should be directly accessible in the drive’s root directory.

Updating the BIOS Using M-FLASH

The M-FLASH utility is integrated into the BIOS and provides a straightforward method for updating the BIOS.

Enter the BIOS Setup: Restart your computer and press the Delete key (or the appropriate key for your system, usually displayed during boot-up) to enter the BIOS setup.
Navigate to M-FLASH: Within the BIOS, use the arrow keys to navigate to the “M-FLASH” option. This is often found under the “Utilities” or “Tools” section.
Select M-FLASH: Select the “M-FLASH” option and press Enter. The system will restart and enter the M-FLASH utility.
Select the BIOS File: In M-FLASH, the utility will display a list of available storage devices. Select your USB drive. The utility will then display the BIOS file that you copied earlier. Select the BIOS file.
Confirm the Update: The utility will ask you to confirm that you want to flash the BIOS with the selected file. Double-check that you have selected the correct BIOS file for your motherboard. Confirm the update.
BIOS Flashing Process: The BIOS flashing process will begin. Do not interrupt the process. Do not turn off the computer during this time. A power outage or interruption during the flashing process can brick your motherboard.
System Restart: Once the flashing process is complete, the system will automatically restart.
Load Defaults: After the restart, enter the BIOS setup again and load default settings. This ensures that the new BIOS settings are properly applied. You can then customize the BIOS settings as needed.

Updating the BIOS Using BIOS Flashback (If Applicable)

Some MSI motherboards feature BIOS Flashback, which allows you to update the BIOS even without a CPU, RAM, or GPU installed. This is especially useful if your system is not booting due to a corrupted BIOS. The B550M Pro-VDH Wi-Fi, fortunately, does support BIOS Flashback.

Prepare the USB Drive: Follow the same steps as described above for preparing the USB drive, ensuring it is formatted as FAT32 and contains the BIOS file in the root directory.
Rename the BIOS File: This is crucial for BIOS Flashback to work. Rename the BIOS file to MSI.ROM.
Insert the USB Drive: Locate the BIOS Flashback port on the rear I/O panel of your motherboard. Insert the USB drive into this port. This port is usually labeled and may be a different color.
Press the Flashback Button: Locate the BIOS Flashback button on the rear I/O panel. Press and hold the button. The LED next to the button will start flashing. Release the button.
Wait for the Flashing Process to Complete: The LED will continue flashing, indicating that the BIOS is being flashed. The flashing process can take several minutes. Do not interrupt the process. Do not turn off the computer during this time.
LED Behavior: When the flashing process is complete, the LED will either turn off or stop flashing. This indicates that the BIOS update is finished.
Power On the System: You can now power on your system. The new BIOS should be loaded. Enter the BIOS setup and load default settings.

Post-Update Verification

After updating the BIOS, it’s essential to verify that the update was successful and that your system is functioning correctly.

Check the BIOS Version: Enter the BIOS setup and verify that the BIOS version displayed matches the version you just flashed.
Test System Stability: Run some stress tests or use your computer as you normally would to check for any stability issues.
Monitor Temperatures: Keep an eye on your CPU and GPU temperatures to ensure they are within acceptable ranges.
