BIOS image for the HP 440 G2 notebook using the Compal LA-B181P motherboard, marked M73, packed as a 4.71 MB ZIP. Unlike the full DMI variant, the name does not say whether identification data is included, so check serial and model fields after flashing. Compal uses the LA-xxxxP pattern for its board codes; confirm it on the PCB. Read and save the original flash content with an SPI programmer before writing, and ensure the dump size equals the chip size or it will not fit.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
