BIOS protection jumper [JP16]
This jumper protects the BIOS memory from being overwritten. It is a safety mechanism
to avoid accidental or malicious BIOS flashing. If the jumper is positioned so that it
covers pins 2 and 3, the BIOS will not allow any flash utilities to overwrite it. If the BIOS
needs flashing, the pins must be covering pins 1 and 2 (see image below).
