ASUS X750JB laptop BIOS for mainboard revision 2.0, an 8MB image packed in a RAR archive. The 8MB size corresponds to a 64Mbit SPI flash chip, which a technician can rewrite with an external programmer when the laptop fails to post or after a corrupted update. Make sure the board revision printed on the PCB is 2.0 before using it. Read and store the original chip contents first, since serial number and LAN MAC details may need to be transferred back after flashing.
