BIOS firmware package for the MSI Z68MA-G45 desktop motherboard, revision B3, carrying MSI's own board code MS-7676. MS-numbers are MSI's internal model identifiers and are printed on the PCB, usually between the slots, so confirm both the code and the B3 marking before using the image. The RAR archive, 13.0 MB, should be unpacked and the contents checked before flashing. Technicians typically write such an image to the SPI BIOS chip with a hardware programmer when a board will not post, after first saving a backup of the original chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
