BIOS archive for the ASRock B560M-HDV desktop motherboard, sized for a 16MB flash chip. The RAR is 17.1 MB, so it may include extra files beside the image; extract it and pick the file of exactly 16 MB for the SPI chip. Technicians use such dumps to recover boards with corrupted firmware using a CH341A or similar programmer. Back up the original chip first, since it holds board-specific data such as the MAC address.
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.
