Is it possible to update with QFlash ?

Wonderful relay race!

After flashing the BIOS, please configure BIOS parameters again:

• Start with F7 (Load Optimized Defaults)
• Remember also to disable CFG-Lock from Boot section and to enable Vt-d
• Also please uncheck the current Thunderbolt SSDT in ACPI section of config.plist and add/enable the new one attached.

Then perform a cold boot (shutdown computer, pull power cable or flip PSU power switch for 15 seconds). When system restarts:

• Check if Ethernet and WiFi are okay
• Check if Antelope interface is still okay
• In IORegistryExplorer, click on NHI0 (under RP05) and post a screenshot

Of course! That's the only way... Nice and easy.

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.

Oh snap! So Audio passes through without issues!?!?

D'oh! I thought I need to set the number of threads inside of the CpuTSCSync kext, and in trying to find the value in PlistEditPro, I caused all kexts to now show as folders.
I tried rebuilding Launch Services, but I think the command is for Sierra, because it didn't take. Does anyone have a Terminal Command solution for this?

• Is this for the Z390 Designare?
• Do you have a bootable backup? If so, simply grab the working EFI folder from there.

I have the Fenvi installed in a PCIe x1 slot (short slot). Is it the same for you?

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?

Do I risk screwing up the backup by mounting it on an online system with this "kexts as folders" problem? I wanted to ask before I attach backup SSDs...

This is exactly what we're trying to find out with @yosoyoco. On the same Z390 Designare, enabling Vt-d has disabled his Ethernet and WiFi. On my Z390 Designare with the new BIOS, enabling Vt-d does not affect Ethernet or WiFi.

The BIOS was not explicitly modified to allow for the Fenvi card to work. Instead, it was modified to include:

• Apple Thunderbolt PEI/DXE drivers
• AppleVTD DXE driver
