I can give a try too

Can you verify under MaciASL, if you have DMAR table appearing
I also have the network errors and for me the DMAR table appears under MaciASL. Nothing is entered in the config.plist under "ACPI - Delete".

...as a quick note, on my ASUS Prime X299 Deluxe, the Thunderbolt-to-Gigabit Ethernet adapter works great. AVB included! It is connected to a Gigabyte Titan Ridge card. With unmodified firmware.

With BIOS modified firmware, I have tried booting to Windows, from cold boot and thunderbolt eGPU plugged before :
  • During post boot (prior OpenCore picker), eGPU discrete card (RX580) fans have increased speed ... good sign !
  • Few time after Windows desktop appearing, eGPU fans has shortly speedly spinned and then stopped
  • eGPU is connected and ready to go :)
Bad news are :
  • when I have both thunderbolt Ethernet and eGPU devices connected (Port 1 and 2) before boot, due to a lack of memory ressources : both can't connect under Windows (only one device at same time works)
  • Hot plug doesn't work (maybe something to do on SSDT... this may solve previous point)
  • From a warm boot and eGPU already plugged, Opencore doesn't boot, I have black screen with a white cursor > System seem to be stucked

@maschinenwart

On your ASUS board, have you enabled AppleVTD ? Which macOS version have you installed ?

@maschinenwart @yosoyoco

if someone have some times, could you extract from Hackintool / Logs / Systems, all lines related to "IO80211Family". If there is too much lines .. 20 first lines would be sufficient

Yes, it is enabled...

Catalina V. 10.15.7 (19H1217)

...the Log from Z390
Apple Thunderbolt-to-Gigabit Ethernet adapter has always worked in Catalina even without Vt-d. It fails, however, under Big Sur unless Vt-d is enabled.

That would be great. Will send the new BIOS to you.

IDK if this helps, but VTD seems to be working for me with both i211, i219, and WiFi/Bluetooth working and connecting in Mojave.
EDIT: @CaseySJ should I hunt for a special revision or batch number on my Z390? Would you like a copy of my BIOS, BIOS setup file, and OC070 bundle? LMK...
Good to know everything works in Mojave! This could be an option for Antelope Audio users if we cannot solve the Ethernet and WiFi problems under Big Sur with AppleVTD.

I wonder if everything will also work under Catalina with AppleVTD enabled.

hi, I have a problem, my Fenvi card prevents the computer's boot. When I remove it the boot goes well but when it is plugged in the computer lights up and comes off at the end of 1-2s. I do not understand why ... Thank for your help
Hello @SCaRL3T,

Some questions and suggestions:
  • Which version of BIOS is installed?
  • Which slot is the Fenvi plugged into?
  • Have you tried moving Fenvi to another slot?
  • Have you tried CMOS Reset?
  • What other PCIe cards are installed?
  • How many NVMe SSDs are installed?
  • What are the makes/models of all NVMe SSDs?
