Working BIOS dump for the C55-B laptop, based on the Compal board LA-B303P with the ZBWAA platform code, in a 4.20 MB ZIP. The working status suggests it was used successfully on a real board, which is useful when the original firmware is corrupt. Compal uses the LA-xxxxP numbering, so read the board number on the PCB to confirm a match. Back up the existing SPI chip with a programmer before writing, and check that the image size matches the flash capacity.
