BORD

The BORD (BOaRD) tag is an 8-bit unsigned integer that contains the Board ID of the device that the firmware image is supposed to be ran on. It allows Apple to make sure you are not running another device's firmware files on an incompatible device, probably to prevent using old exploits. What is odd about this tag is that the same values have been used many times.
