Working BIOS image for the MSI Z77A-GD65 desktop motherboard, board MS-7751, with the vAB token pointing to its version marking. Supplied as an 18.5 MB RAR, so extract it and pick the file that matches the size of the SPI flash on the board. Use it to recover a board that fails to post after a corrupted update, writing it with an external programmer. Read and keep the original chip contents first, and check the PCB version matches before flashing.
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.
