Firmware set for the Dell Latitude E6420 on Compal board LA-6592P, revision 2.0, including both the main BIOS and the EC BIOS in a 5.15 MB ZIP. LA-6592P is a different Compal board from LA-6591P, so check the PCB marking before use. Technicians use such images to reprogram the SPI flash and EC chip with a programmer after corruption or failed updates. Save the original contents first and confirm the image sizes match the flash chips on the board.
