BIOS firmware for the ASUS TUF Gaming X570-Plus (Wi-Fi) motherboard, stored in an 18.2 MB RAR archive. The name gives no version, revision or tested status, so check what the archive holds before relying on it. X570 boards use a large SPI flash, and a dump like this is typically programmed with an external programmer after a failed update or corrupted firmware. ASUS retail capsule files differ from raw chip images, so confirm which one you have, back up the original chip, and check the image size against the chip capacity.
