BIOS archive for the ASUS N53J laptop, main board N53JN revision 2.0, in a 1.58 MB rar. ASUS prints the board name and revision on the PCB, usually near the memory slots or the edge of the board. Check these before using the image. The file is meant for SPI programming to fix a corrupted BIOS or a board that will not boot. Make a backup of the existing chip, and confirm the image size fits the installed flash part.
