ASUS P8H77-M PRO desktop BIOS, supplied as a BIN image inside a ZIP of about 4 MB. The name also carries CM6870 and 0708; the latter looks like the firmware version, but neither token is explained, so check the contents before flashing. The board uses the Intel H77 chipset. A raw BIN image is meant for writing directly to the SPI flash with a programmer when the board will not POST. Read and save the existing chip first and make sure the image size matches the flash capacity.
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.
