Let's try the attached BIOS parameter file (from Elias) as follows:
  • Copy the uncompressed file to a FAT32 partition or any EFI partition. A USB flash disk can be used.
  • Insert the USB flash disk and go to BIOS Setup --> Save & Exit
  • Select the last option on the page, to Load Profile
  • Select the sub-option to Load Profile from Disk
  • All FAT32 and EFI partitions will be shown; select one (don't worry if you don't know which is the right one; just click on each of them until you find the file BIOS-4-setting
  • Select BIOS-4-setting
  • When file has been loaded, click Save & Exit
  • Now check if Ethernet and WiFi are working
    • Please report if Ethernet is okay or not okay
    • Please report if WiFi if okay or not okay
No Ethernet
No Wifi

FYI- I just tried booting into latest Big Sur public beta, same exact behavior on network interfaces, with the exception of the thunderbolt ethernet adapter that works.

  • Do you have the Fenvi FV-T919?
  • If so, which slot is it in? Is it in the short PCIe x1 slot?
Yes, Fenvi T919 in slot PCIEX1_2
Yep, last stable IntelMausiEthernet 1.0.6
And disableIOmapper = false ??

It's seems to be related to DMAR ACPI table or something like that...

Enabling VTD, ethernet and wifi stay disconnected. No wifi kexts.

Ok, I post my reply with my phone because I have no more ethernet/wifi with vtd enabled. Finally, my orion32+ works on z390 F9i original firmware, with vtd enabled.

Yes, that’s where I have it. Was the modified BIOS you’re running intentionally changed to allow for the Fenvi card to work? Or is that a behavior you’re seeing as a result of the previous work?

@CaseySJ I don't have any audio devices or that BIOS you're testing, but I decided to see what happened if I enabled Vt-D on my build. I was turning it off with DisableIoMapper and leaving it on in the BIOS.

With it fully enabled, both built in ethernet ports break as well as my Fenvi Wi-Fi. The Aquantia 10Gbps NIC in my Z390 doesn't break though.

The 2 built in ethernet ports stay at "not connected", and they swap positions every few seconds if I watch the list of interfaces in network settings.
On my Gigabyte Z490 Vision D with ...
  • Big Sur 11.5 Beta 3
  • Fenvi FV-T919 in PCIe x1 slot
  • Vt-d enabled (AppleVTD)
  • Standard Gigabyte F5 BIOS
  • DisableIoMapper turned off
  • "dart=0" removed from boot-args
... I observe the following behavior:
  • Apple Thunderbolt-to-Gigabit Ethernet adapter works
  • Fenvi WiFi does not detect any SSIDs and does not connect
    • Driven by AirPortBrcmNIC.kext (native)
    • The crossed-out symbol appears on the icon in menu bar after several failed connection attempts
    • No connection is established
  • Built-in Intel i219 Ethernet port:
    • Driven by IntelMausi.kext; the (non-native) kext is loaded and attached
    • The port tries to establish an Ethernet connection
    • The yellow and orange LEDs on the Ethernet port blink momentarily and then turn off; then cycle again
    • No connection is established
  • Built-in Intel i225-V Ethernet port (2.5Gbps)
    • Driven by AppleInteli210Ethernet.kext (native)
    • The port works perfectly
This message posted from Z490 Vision D with Vt-d enabled and Intel i225-V connected.

It would be interesting to, prior save your BIOS profil on disk drive (EFI drive or other FAT32 drive) to recover all BIOSs setting at the end, then :
  1. make a NVRAM reset, then cold boot and verify if network back to life
  2. If not, make a Clear CMOS (shorting few second on mother board the following shunt indicated by red arrow), then cold boot and verify if network back to life

@yosoyoco,

Have you tried these suggestions?
