BIOS firmware for an MSI laptop with a Core i7 processor and GTX 1050 graphics, board MS-16J91 version 1.0, in a 4.46 MB RAR. The U61 Part token is unclear from the name alone. MS-16J9x numbers follow MSI's internal board numbering. Technicians write such an image to the SPI BIOS chip with a programmer to recover a board that does not post or has a corrupted firmware region. Back up the original contents first and verify that the PCB reads MS-16J91 and the image size matches the flash chip.
