Vital:

What on the Open Core website isn’t correct for my motherboard. In my case, I need this value: 00009B3E instead of 07009B3E, otherwise it’s a black screen

But that’s a very specific case. If I would connect my display through the DP, maybe the old value would work.

  • 0x07009B3E — or BwCbPg== — original
  • 0x00009B3E — or AACbPg== — fixed
