BIOS for the MSI ZH77A-G43 desktop motherboard, model code MS-7758, labelled as an 8 MB image inside a 15.4 MB RAR archive. The archive is larger than one image, so it likely holds several files; inspect it before flashing. MS-7xxx is MSI's own board numbering. An 8 MB dump fits a 64 Mbit SPI chip and can be written with a programmer to recover a board with bad firmware. Back up the original chip and confirm the MS-7758 code on the PCB first.
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.
