BIOS firmware for an FM2A55M-HD+ desktop motherboard, version P1.20, supplied as a 4.44 MB RAR archive. The board name and version style follow ASRock naming for AMD socket FM2 boards with the A55 chipset, although the brand is not stated in the file name. A file like this is used to reflash a corrupted BIOS chip with an SPI programmer or to restore a board after a failed update. Back up the existing chip contents first and make sure the image size equals the capacity of the flash chip fitted on the board.
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.
