Raw 8.00 MB BIOS dump for a laptop motherboard numbered LA-B303P, with ZBWAA as the project code printed alongside it. The LA- prefix follows Compal numbering, and Compal builds boards for several notebook brands, so the laptop maker is not stated here. The size suits a 64 Mbit SPI flash chip and can be written with a hardware programmer when a board will not post or shows a corrupted BIOS. Check the PCB silkscreen matches LA-B303P and keep a backup of the original chip before writing anything.
