MSI B450M PRO-M2 MAX BIOS archive, board code MS-7B84, packed as a 26.4 MB RAR. This is an AMD B450 chipset micro-ATX board; the name lists no firmware version, so inspect the contents to see which release and whether a raw dump or a vendor update file is included. A clean image is used to revive a board bricked by a failed flash by writing the SPI chip with an external programmer. Verify the MS-7B84 code printed on the PCB, keep a backup of the existing chip, and confirm the image size fits the flash.
