BIOS archive for the Dell Latitude E5540 with Compal board LA-A101P, revision 1.0 (A00), labelled working. It covers three chips named U1, U2 and U7, which suggests split BIOS images plus possibly EC or other firmware for separate flash devices. Compal uses the LA-xxxxP pattern for its laptop boards. Identify each chip location on the PCB, read and back up the originals, and confirm each image matches the capacity of its target chip before programming with an SPI programmer.
