BIOS dump for the Dell Latitude 7490 on Compal mainboard LA-F322P, archived in RAR with the Management Engine region cleaned. LA-xxxxP is Compal's board-numbering pattern, so the code printed on the PCB must match. A cleaned ME is useful when the laptop boots with errors, shuts off after a set period or shows ME firmware failure. Write it with an SPI programmer after dumping the original chip, since service tag and other system data live there and may need restoring.
