Working BIOS for the MSI B150M MORTAR motherboard, board code MS-7972, stored in a 42.2 MB RAR archive marked as fully tested. MSI's MS-xxxx codes identify its own desktop boards, and this B150 chipset model supports Intel Skylake processors. The large archive size suggests it holds more than a single image, so check the contents. Use a programmer to read and save the current SPI chip before writing, and make sure the chosen image matches the flash capacity.
