BIOS image for the MSI MS-16U51 notebook board, version 1.0, delivered as an 11.7 MB RAR archive. MSI uses MS-prefixed numbers for its own board designs, and the same code is usually printed on the PCB. Technicians flash such an image onto the SPI chip with a programmer when a board stays dead or loops after a failed update. Back up the original chip, make sure the extracted image is the same size as the flash, and confirm the board number before writing.
