The board number appears with the letter O where Quanta normally uses the digit zero, as in DA0X8P. At 11.7 MB it may contain a main BIOS image and possibly an EC dump. Check the board number on the PCB, read and save the original SPI contents, and confirm that each image size matches its chip before programming.
