BIOS dump for the Dell Latitude E7450 on the Compal ZBU11 board, number LA-A963P revision 1.0. Compal uses the LA-xxxxP pattern for its motherboard numbers, and ZBU11 is the project code printed alongside it. The 6.51 MB RAR holds the firmware image for restoring the SPI flash with a hardware programmer after a failed update or corrupted region. Confirm LA-A963P and Rev 1.0 on the PCB, back up the original contents including service tag data, and ensure the image size fits the chip you are writing.
