BIOS firmware for an N53SV mainboard, revision 2.2, the ASUS N53 series design, though the brand is not written in the name. Packed as a RAR of about 1.46 MB, so check what the archive holds and whether the image inside matches the SPI chip capacity on your board. The revision number printed on the PCB should read 2.2 before you rely on this dump. Technicians write such files with an external programmer after a failed update. Always back up the existing chip first.
