Dell OptiPlex 9020 MT

Haswell i7-4790

16 GB RAM

Monterey 12.6

MSI RX 6600 Mech dGPU in 16x slot

I used the OptiHack guide and files here to install. It ran really great except I had some graphics glitches with the iGPU with Brave Browser. I bought an MSI RX 6600 Mech to upgrade and fix the glitches in Brave.

Now I can't get past the Black Screen at boot. I've added -adgpmod=pikera too boot agrs, I also disable gpu and disable hdmi patches as explained here in the OptiHack guide. I've also tried booting with the AMD as primary display and Auto (which disables the iGPU) from BIOS. I have also tried disabling and enabling Legacy Boot options in the BIOS and I still can't get past the black screen.

I'm thinking maybe the DSDT files included with the OptiHack guide aren't quite right so I'm submitting the Send me extract from the machine. I'm not sure where to go from here. Hopefully a proper patch can fix it.
