Firmware archive for the HP ZBook 17 G2 mobile workstation, labelled for motherboard LA-B391P, which uses Compal numbering. Packed as a 6.67 MB RAR, it should contain a BIOS image intended for the SPI flash on that board. Typical use is reprogramming a dead or bricked chip with an external programmer and clip. Before writing, make a backup of the existing chip, check that the image size matches the flash capacity, and verify the board number silkscreened on the PCB really reads LA-B391P.
