Firmware image for the Toshiba Satellite C50 built on Compal board LA-B303P, supplied as a 4.19 MB ZIP. The LA- prefix is Compal's motherboard numbering, so Compal is the ODM for this Toshiba model. Technicians program such a dump into the SPI BIOS chip with a CH341A or similar tool to recover a board that will not post or has a corrupted BIOS. Confirm LA-B303P is printed on your PCB, read and save the original contents first, and make sure the image size equals the flash chip capacity.
