BIOS firmware for the ASRock H55M-LE desktop motherboard, version 1.80, stored in a 956 KB ZIP archive. It may be the vendor update file or a raw dump, so check whether the image inside is the full size of the flash chip before programming it directly. Technicians use such files to recover a board that will not POST after a failed update, by flashing the SPI chip with an external programmer. Back up the original contents first and confirm the board model matches exactly.
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.
