BIOS firmware package for the Dell Latitude E5570, built around the Compal motherboard LA-C642P with the ADM80 project code noted in the name. The 15.8 MB RAR archive likely holds one or more SPI flash images rather than a single file, so open it and check sizes before use. LA-xxxxP numbering is the Compal pattern, so confirm the code silkscreened on the PCB matches. Read and save the original chip contents with a programmer such as a CH341A before writing anything, and make sure each image matches the capacity of the flash chip on the board..
