MSI desktop motherboard BIOS for MS-7599, version 2.1 of the board, in a 720 KB RAR. MS-7xxx is MSI's own numbering for its motherboards, printed on the PCB near the slots, which helps confirm the exact match. A firmware image like this is used to recover a board after a failed update or chip corruption, either through a programmer or the vendor flashing method.
