Firmware archive for the ASUS Z87-PLUS desktop motherboard, 10.6 MB ZIP. The name gives no BIOS version, so it is not clear whether the archive holds a stock release file, a dump from a working board, or several versions together. Open it and identify the contents before use. A BIOS image like this is typically written to the board's SPI flash with a programmer, or through ASUS's own flashing tools, to recover a board that no longer posts. Save the original chip contents first and make sure the image size equals 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.
