BIOS image for the Toshiba U940 laptop built on Compal board LA-9161P, with VCUAA appearing as a code in the name. The LA-xxxxP numbering is Compal's scheme, so Compal designed this mainboard for Toshiba. The ZIP is meant for reprogramming the SPI flash on units with no POST, no display or corrupted firmware. Check the LA number on the PCB, read and store the original chip contents first, and make sure the image size equals the flash chip capacity before writing.
