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.
