Updating the BIOS on an old MSI motherboard where the download is a single executable.
I had an old motherboard I wanted to upgrade the BIOS on before turning it into the basis for a Plex media server. In particular, it was a MSI H61M-E33 (B3). The latest BIOS download was a ZIP file that contains a single executable file. That won't work for the M-Flash instructions that the website provides. Creating a bootable flash drive with DOS on it did the trick. I would think this method would work for any other BIOS upgrades that contain just the executable.
- Download rufus. Rufus is a utility to help create bootable USB drives.
- Insert your USB drive. Rufus will format this drive, erasing all data.
- Start up Roofus and choose the following options
- Your USB drive
- Boot FreeDOS
- Press START button.
- Once the process is complete, press CLOSE button.
- Copy the BIOS executable to the bootable USB drive.
- Reset to boot the USB drive.
- At the DOS prompt, run the executable and follow the prompts.
That took care of it for me.
