Unlocked BIOS dump for the HP 640 G3 notebook on motherboard 6050A2860101, MB revision A01. Boards numbered 6050Axxxxxxx follow the Inventec pattern used in many HP business laptops. An unlocked image is typically one with password or security locks removed, used to restore access to machines locked by a BIOS password. The 7.53 MB RAR is written to the SPI flash with a programmer; save the original chip first, since it holds unique serial and system data, and confirm the board number and A01 revision.
