MSI desktop board MS-7687 BIOS, version 4.2, offered in both 2 MB and 4 MB variants inside one RAR archive. Two sizes exist because boards of this model may be fitted with different flash chip capacities. MS- numbers are MSI's own board codes. Read the marking on the BIOS chip to pick the correct image, since a file that does not match the chip size will not fit. Back up the original contents with a programmer before reflashing a board that no longer posts.
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.
