Modified firmware for the ASUS X55VD that disables the onboard RAM, with no board revision stated in the name. Used when soldered memory is defective, it lets the laptop start using the expansion slot only, after a working SO-DIMM is installed. Program it to the SPI flash with a hardware programmer. Because the revision is not given, compare the board marking on your PCB with the file contents carefully, read and keep the original chip, and confirm the chip capacity matches the image before writing.
