Working BIOS for the HP ProBook 470 G2, which uses the Compal-made motherboard LA-B181P. The 7.88 MB RAR holds a dump that you write with an SPI programmer to recover the board. Compal designs carry LA-xxxxP codes on the PCB; confirm the number, and the revision if one is shown, before you flash. Some HP boards need the serial number, model data and product ID re-entered after programming. Back up the original chip first and confirm that the image matches its capacity.
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.
