But there is no "Cancel" button.

Exactly. Feel like I'm going crazy! LOL

Let's abandon the A1/A2 experiment...

It was a little joke

In almost all cases, the TB monitor almost never shows anything, or even lights up. I don't know if what I did works on the old BIOS, but the most consistent way for me to cause it to happen was to enter BIOS setup with a standard monitor (I'm using an LG 27UK650 over HDMI) then plugging the Thunderbolt cable into the LG UltraFine 5K (already plugged into AC power), waiting for video loss, then holding down the case power button and quickly pressing it to power back on.

The video import sounds interesting, as I suspect the BIOS fails to initialize the monitor on it's own without dGPU. I've also been curious how it handles in an RX 6800 XT USB-C port, but I haven't been able to get one.

@Elias64Fr,

Have you noticed any Apple video drivers (PEI or DXE) that we could import into the Z390 Designare BIOS? If so, maybe they could provide better support for Thunderbolt monitors during early stages of boot?

I FIXED MY USB ISSUES!!!!

I now have full TB3 with Antelope and all working USB2/3 and Networking!!!!!!

I had to set ReleaseUSBOwnership in OCConfig to true!


The Antelope Remote Control Panel still disconnects from my main rig after 2 minutes. I am going to order more ram tonight to see if I can run more than 2x 8gb sticks.

Are the DIMMs in A1 and B1?

Because each DIMM exceeds 8GB, it may be necessary to configure the Memory section regardless of how many DIMMs there are.

Once my liquid cooler is replaced, I’ll continue the tests on my end.

They show up under BANK 0/ChannelA-DIMM0, and BANK 2/ChannelB-DIMM0.

I'll try mapping the memory.

Awesome! Finally it works...

Very good thinking.

But from iOS there is no timeout?

I tried this earlier today with two 16GB DIMMs. Alas, it did not work.

Correct, There is no Timeout on the iOS application. The other observation I had is this:

-Boot System with Antelope Launcher closed : Remote System connects and can be used normally with no timeouts
-Antelope Launcher is then Opened: Remote system will stay connected for 10seconds-2min and then timeout.

Ioregistry Explorer will then have:
IOThunderboltFamilyUserClient Red/Crossed out
Apple HPMUserClient Red/Crossed Out
Apple HPMUserClient Red/Crossed Out

@Elias64Fr,

Yes, there is 2 interesting graphic drivers : CoreEG2 and CoffelakeGraphics DXE drivers.
Both already imported on my custom firmware.

When I boot with "PCIe 0 Slot" on BIOS settings, theses drivers don't load on IGPU device.
When I boot with "IGFX" on BIOS settings, theses drivers don't load on IGPU device, another IntelGOP built-in driver has been loaded.
