BIOS archive for the Dell Latitude 7310, built on Compal motherboard LA-J261P, with the token JRPNN53 in the name. That token is probably a service tag or serial reference, but this is not certain. Dell Latitude boards from Compal carry LA-xxxxP numbers on the PCB, and their SPI flash can be read and rewritten with a programmer to clear corruption or recover from a failed update. A dump tied to one unit may carry that unit's identity data. Verify the board number and keep a backup of the original chip.
