BIOS dump for the ASUS U36SD laptop mainboard, revision 2.1, in a 1.50 MB RAR archive. The stated revision lets the image be matched to the right PCB before writing. A technician uses this file to restore the SPI flash with a programmer after a failed update, corrupted settings or a no-POST condition. Before programming, read and save the existing chip, compare the rev 2.1 marking printed on the board, and verify that the extracted image size equals the flash chip capacity to avoid write errors.
