Black screen after verbose

Hey there, everyone!

I've been working hard on installing Mac OS Big Sur on my Dell Precision 5510 laptop, and I've made some progress! I managed to get Big Sur up and running, although I have no graphics acceleration. When I set the platform ID to 00001219, my laptop's screen goes black, but interestingly, when I connect an external monitor, everything works fine on the external monitor, including graphics acceleration.

I've tried various platform IDs for Skylake, but unfortunately, some attempts resulted in freezes or reboots after the verbose log. I also experimented with different SMbios settings, but haven't had any luck so far.

If any of you have encountered a similar situation or have any advice to share, I'd greatly appreciate it! Thanks in advance for your help and support! 😊

Here are my laptop specifications, in case anyone has some insights or suggestions:

  • Dell Precision 5510 Laptop
  • Intel Core i5-6300HQ
  • 16GB DDR4 RAM @ 2133MHz
  • 256GB SSD Storage M.2
  • Intel HD Graphics 530
  • 15.6" HD Display with 1920x1080 resolution

Edit 1: I wonder If I can in any way patch the framebuffer from HDMI to the laptop display?
