BIOS for the ASRock FM2A55M-DGS desktop motherboard, version 1.06, sized for a 4MB flash chip. This micro-ATX board uses the AMD FM2 socket with the A55 chipset, and the dump can restore it after a failed update or corruption that prevents POST. The RAR archive is larger than the image itself, so it may include extra files worth reviewing. Write the BIOS with an external programmer, keep a backup of the existing chip, and confirm the extracted image is exactly 4MB to fit the 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.
