BIOS firmware for the HP ZBook 17 G2 workstation laptop, board LA-B391P, stored in a 10.6 MB zip archive. LA-prefixed numbers belong to Compal, the ODM that built this board for HP. The name does not specify version or chip, so check the archive contents and file sizes. Repairers use such images to reprogram the SPI flash on units with corrupted firmware or after board swaps. Keep a backup of the original chip, since HP stores serial and system data in it, and confirm the image fits the chip size.
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.
