Firmware archive for the MSI B150M MORTAR desktop motherboard, model code MS-7972. At 44.4 MB the RAR likely holds more than a single image, so inspect its contents after extracting. A technician typically uses such files to restore a corrupted BIOS by writing the image to the SPI chip with an external programmer. Before flashing, back up the existing chip and confirm the file size matches the flash capacity. MS-xxxx numbers are MSI's own board codes, so verify the code printed on the PCB.
