BIOS settings

Disable secure boot

Set Graphics to Hybrid mode

Patching DRM

Use iMac20,2 SMBios for full DRM while WX card is active

2 GPU Modes, you can choose UMA config (turns DGPU off, use with unsupported Nvidia DGPU or to save power) or Hybrid+Mux which is the new mode that has everything that Discrete mode plus IGPU for compute and Intel quicksync..

** WX-4170 GPU now works in Catalina/Big Sur/Monterey/Ventura thanks to @EdwardGeo!! ** - Will need to flash the included rom to your card.

I use SSDT-xNVME.aml to completely disable my windows NVME drive that is not compatible with OSX and causes kernel panics if mounted read/write and also randomly at boot. I find it's more reliable than just not mounting the volume editing fstab. It needs to be enabled in the ACPI section in config.plist and adjusted to your non-compatible NVME drive path.

ACPI DMAC and DMAR tables have been updated in OC-VTD version to allow AppleVTD to load and have better Thunderbolt 3 support for devices like Apple's thunderbolt to ethernet adapter and (not tested yet) some audio interfaces. ** Bios VT-d option needs to be enabled for this feature.

For Thunderbolt 3 with most current HP firmware flashed, there's a Bios glitch that doesn't allow us to select "No Security" as an option. To fix it, you need to switch Thunderbolt to "Legacy Mode" in Bios/Advanced/Ports. then reboot, then go back to Bios/Advanced/Ports and under Thunderbolt security the option -No Security- appears, select it and reboot. Now go back to Bios Setup again, and in Bios/Advanced/Ports/Thunderbolt, switch the "Legacy" option back to "Native+Low power" You now have working TB3 ports with hot plug across all OS's

PolarisZBook_WX4170 is custom plist kext to inject power play tables and device properties to the AMD Video driver for better power management.
