What is M-Flash and How to Use It?
If you have a MSI motherboard, you may have heard of a feature called M-Flash. But what is it exactly and how can you use it to update or backup your BIOS? In this article, we will explain what M-Flash is, why you should use it, and how to use it step by step.
Introduction
The BIOS (Basic Input/Output System) is a small piece of software that controls the basic functions of your motherboard, such as booting, memory, CPU, and hardware settings. The ME (Management Engine) is another component that provides security and power management features for your system.

Both the BIOS and ME are stored in a chip on your motherboard, and they can be updated by flashing new versions of them. Flashing means overwriting the existing data with new data. Updating your BIOS and ME can improve your system performance, stability, security, and compatibility.
What is M-Flash?
M-Flash is a technology developed by MSI that allows you to conveniently flash, or update, your BIOS and ME from the BIOS setup utility. You don't need to use any external software or bootable media to do this. You just need a USB flash drive with the latest BIOS and ME files on it.

Why use M-Flash?
M-Flash has several advantages over other methods of updating your BIOS and ME. Here are some of them:
It is easy and fast. You don't need to download or install any software or create any bootable media. You just need to copy the files to a USB flash drive and follow a few simple steps.
It is safe and reliable. You don't need to worry about any power outage or interruption during the update process. M-Flash has a built-in recovery mechanism that can restore your BIOS and ME in case of any failure.
It is versatile and flexible. You can use M-Flash to update both your BIOS and ME at the same time, or separately. You can also use M-Flash to backup your current BIOS and ME to a USB flash drive, or restore them from a USB flash drive.
How to use M-Flash to update BIOS and ME
In this section, we will show you how to use M-Flash to update both your BIOS and ME at the same time. If you want to update them separately, you can follow the same steps but choose only one file to update.
Step 1: Prepare a USB flash drive
You will need a USB flash drive with at least 16 GB of free space. Format it as FAT32 using your computer. Make sure there are no other files on it.
Step 2: Download the latest BIOS and ME files
Go to the MSI website (https:// msi.com) and find your motherboard model. Download the latest BIOS and ME files for your motherboard and save them to your computer. Make sure they are compatible with your current BIOS and ME versions. You can check your current BIOS and ME versions by entering the BIOS setup utility and looking at the information on the top left corner of the screen.
Step 3: Copy the files to the USB flash drive
Connect your USB flash drive to your computer and copy the BIOS and ME files to it. Do not rename or unzip the files. Safely eject the USB flash drive from your computer.
Step 4: Enter the BIOS setup utility
Shut down your computer and connect the USB flash drive to one of the USB ports on your motherboard. Turn on your computer and press the Delete key repeatedly to enter the BIOS setup utility. You may need to press a different key depending on your motherboard model. Refer to your motherboard manual for more details.
Step 5: Select M-Flash from the Advanced menu
In the BIOS setup utility, use the arrow keys to navigate to the Advanced menu and press Enter. Then, select M-Flash and press Enter again. You will see a warning message that says "All data on hard disk drives will be destroyed while updating BIOS/ME. Are you sure you want to continue?" Press Yes to proceed.
Step 6: Choose the USB flash drive and the file to update
You will see a list of available devices and files on the screen. Use the arrow keys to select your USB flash drive and press Enter. Then, select the file that matches your BIOS or ME update and press Enter again. For example, if you want to update both your BIOS and ME, select the file that has both BIOS and ME in its name.
Step 7: Confirm and start the update process
You will see a confirmation message that says "Are you sure you want to update this file?" Press Yes to start the update process. Do not turn off your computer or remove the USB flash drive during this process. You will see a progress bar on the screen that shows how much of the update has been completed.
Step 8: Wait for the update to finish and reboot the system
When the update is finished, you will see a message that says "Update Success! It will auto reboot after 5 seconds." Wait for your system to reboot automatically. Do not press any key or turn off your computer manually. After rebooting, you will see a message that says "BIOS/ME Update Complete! Press F1 to Run SETUP." Press F1 to enter the BIOS setup utility again and check if your BIOS and ME versions have been updated successfully.
How to use M-Flash to backup and restore BIOS
In this section, we will show you how to use M-Flash to backup your current BIOS to a USB flash drive, or restore it from a USB flash drive. This can be useful if you want to revert to a previous BIOS version or recover from a failed BIOS update.

Step 5: Confirm and start the backup or restore process
If you choose Save Current BIOS To File, you will see a message that says "Please input file name (Max length is 8):". Type a name for your backup file and press Enter. Then, you will see a confirmation message that says "Are you sure you want to save this file?" Press Yes to start the backup process.
