Firmware image for the HP ProBook 430 G2 notebook, Compal board LA-B171P with project code ZPM30, delivered as a ZIP archive of about 4.65 MB containing a ROM file. Compal uses the LA-xxxxP numbering for its motherboards, and this one was built for HP. The dump is meant for restoring a corrupted BIOS by writing the SPI flash with an external programmer such as a CH341A. Before writing, verify the board number on the PCB, back up the existing chip contents, and make sure the file size matches the flash chip 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.
