BIOS image for the HP ProBook 430 G2 built on Compal board LA-B171P, packed as a 3.86 MB rar. The LA- prefix followed by a four-digit code and P is the Compal numbering scheme, so Compal is the board maker behind this HP model. Technicians write the dump to the SPI flash with a programmer to repair corrupted firmware or no-boot faults. Confirm the LA number on the PCB matches exactly, read and keep the original chip, and check that the file size suits the flash part.
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 @biosfilebins. Enginerys does not host this file.
