Working firmware dump for a Dell laptop built on the Compal LA-A911P motherboard, revision 1.0, supplied as a 4.57 MB RAR archive. Compal is the ODM behind LA-prefixed board numbers, and the revision printed beside the number on the PCB should match before you flash anything. Technicians use such a dump to recover a board with a corrupted BIOS chip by writing it with an SPI programmer. Read and keep a copy of the existing chip first, since it holds machine-specific data such as the service tag.
