Modified BIOS dump for the Dell Latitude 5490 with board LA-F401P, a 16 MB binary marked as working with the Management Engine region cleared. LA- numbers follow Compal's board scheme, Compal being the ODM behind this design. The image suits a 16 MB SPI flash and is written with a programmer such as a CH341A after reading and saving the original chip contents, which hold the service tag and board-specific data. A cleared ME region helps recover boards with corrupted ME firmware, though settings may need reconfiguring afterwards.
