BIOS dump for the Dell Latitude E6420, labelled PAL50 with Compal board LA-6591P, provided as a 4.96 MB RAR. PAL50 is the Compal project code shown in the name, and LA-xxxxP is the Compal board numbering style. The image is used to reprogram the SPI flash with a hardware programmer when the laptop fails to post or the BIOS is corrupted. Confirm the board number on the PCB is LA-6591P, make a backup of the existing chip, and check the image size against the flash capacity.
