BIOS firmware package for the ASRock B550 Phantom Gaming 4 AM4 motherboard, version L2.14 according to the name. The 28.2 MB RAR archive likely holds the update image and may include extra files, so inspect the contents before use. A technician can apply it through the board's built-in flashing utility or, on a bricked board, write it to the SPI chip with a programmer after confirming the image size matches the chip. Always back up the original chip contents first, as the dump holds board-specific data.
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.
