Firmware archive for the ASUS B85-PRO GAMER desktop motherboard, containing both BIOS and EC images in a 4.57 MB RAR file. The EC firmware runs the embedded controller, so having it alongside the BIOS is useful when a board stays dead even after a BIOS reflash. Extract the files and write each to its matching chip with a programmer. Read and store the original chip contents first and confirm each image size fits the target flash 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.
