BIOS image for the MSI Z170A GAMING M3 desktop motherboard, board number MS-7978, packed in a RAR archive. A file like this is used to recover a board with corrupted firmware by writing the SPI flash with an external programmer such as a CH341A, or via MSI flashback where supported. Read and save the existing chip contents first, keeping the original MAC and serial data, and make sure the image size equals the capacity of the flash chip fitted on your board.
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.
