BIOS dump for a C55-B laptop on the Compal LA-B303P board, labelled as working, with ZBWAA also appearing in the name, most likely the Compal project code. It comes as a 4.20 MB zip archive. The LA-xxxxP pattern is Compal numbering, and the same board can be used by more than one brand, so check the code printed on the PCB. Before writing the image to the SPI flash with a programmer such as a CH341A, read and save the original chip contents and confirm the image size matches the chip capacity.
