@weekendiac, I have 1909 fully updated.

 

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Thanks a lot! I'll give it a try Smile
Let me know also if you manage to make your Vega 64 work correctly, i suppose that its architecture is similar to my Vega 56.

@vumad, yeah you must deinstall 1909 and go back to 1903.

Just look for solutions „as explained.“

@weekendiac, I have the iso from 1803. Will that work? Or do I need to find a different ISO.

@vumad, hey I’d already copied the link for you.

But for your pleasure; the details:

If you need to do a clean install of Windows 10 1903 V1, a manual update to .295 can be done by downloading:

  • August 13, 2019—KB4512508 (OS Build 18362.295) which can be found Microsoft Update Catalog
  • "2019-08 Cumulative Update for Windows 10 Version 1903 for x64-based Systems (KB4512508)
  • Be careful one is for SERVER, that is not the one that will work with Bootcamp...

@anonymousse, If you want to boot again with your dGPU activated, just change the startup.nsh as follows:

echo -off

fs0:

#\EFI\Boot\apple_set_os.efi

stall 1000000

#mm 00010122 2 ;PCI :BA10 -n

#mm 00010124 2 ;PCI :BA20 -n

#mm 00010126 2 ;PCI :DC10 -n

#mm 7C2 ;IO :1 -n

#mm 7D4 ;IO :28 -n

#mm 7C2 ;IO :2 -n

#mm 7D4 ;IO :10 -n

#mm 7C2 ;IO :2 -n

#mm 7D4 ;IO :40 -n

#mm 7C2 ;IO :1 -n

#mm 7D4 ;IO :50 -n

#mm 7C2 ;IO :0 -n

#mm 7D4 ;IO :50 -n

if not %lasterror% == 0 then

reset -w

endif

\EFI\Microsoft\Boot\bootmgfw.efi

@goalque,

Posted by: @weekendiac

where can I search the correct mm commands for the AMD Radeon Vega 64 ?

And could you please be so kind to explain the different mm rows and their functions?

So I had understood that :

rows 5-7 are for cards which needs bigger memory

rows 8-13 to change the gmux state (whatever that in detail means)

rows 14-17 to power off the dGPU.

Although I am happy with my RX 580 , I must change the script, to get my Vega 64 run and eliminate error 12.

Meanwhile I tried everything, getting my Vega 64 (not) to work. No success!

I think, only the correct mm commands would open the door 

Does anybody knows how to discover these values?

Hi, and thanks again!
I made a clean install of windows 1903 and I am actually stucked with this message when I try to boot with your code to activate the eGpu :
"set os vendor to apple inc .."
Do you have an idea to fix this? I suppose that the apple_set_os.efi does not work properly... I tryed with with the update of the 16th february of this script.

@anonymousse, dones it work under MacOS? 

If you are in doubt of the changes that I had made in the startup.nsh, just use the original of goalque. For me the modifications are fine (with my RX 580), even if the eGPU is unplugged. 
And for me the apple_set_os.efi works great.
