In order to fix the DP black screen on Radeon RX Vega 64
I am testing with different values for Board ID and ProductName.
iMac17,1: 'Mac-B809C3757DA9BB8D' - does NOT work
iMac16,2: 'Mac-FFE5EF870D7BA81A' - works (ProductName however causes KP)
iMac16,1: 'Mac-A369DDC4E67F1C45' - works
iMac15,2: 'Mac-FA842E06C61E91C5' - does NOT work
iMac15,1: 'Mac-42FD25EABCABB274' - need to test
iMac 14,2: 'Mac-27ADBB7B4CEE8E61' - works
With the correct Board ID and ProductName it boots into High Sierra with DP and HDMI
Conclusion: the Board-ID affects how graphics behave and boot
Even with the correct Board-ID a ProductName can cause KP.
I think this is because Mac 'boots' or 'does not boot' based on certain hardware that is compatible with that version of the graphic card and OS.
