BIOS dump for the Dell Latitude E6420 on Compal board LA-6594P, platform PAL50, Rev 1.0. Compal builds boards under LA-xxxxP numbers and labels them on the PCB. This image is used to recover a corrupted or locked BIOS by writing the SPI flash with an external programmer. Read out the original chip first and keep it safe, since the service tag and system data may live there, and verify the chip size before flashing.
