[Solved] Sierra under HP Z620 any help possible ?

[Milsabor]

Hello everybody

has been a week i am trying to install Sierra under my workstation HP Z620...with no success :'(
It is shipped with 2 Intel Xeon E5-2690 and a Nvidia Geforce 1080 Ti + 64 Gb of Ram and a Samsung SSD Evo 850 1Tb

I have tried to configure the Bios as some describe it on the forum for a Z800 ou Z820...in EFI mode without USB3
I am in the first part of the install : booting on the 16Gb USB key..... and trying to play with the flag options etc....

But or i am stuck over there on the Apple logo or when i use the -v it tells me :

Waiting on <dict...
Ethernet [IntelMausi....

Does anyone have the same workstation as mine and can give me the Bios Options and FLAGS he used please ??

Thank you very much

I make a clean and perfect fixed DSDT for my Z620, can't boot into HighSierra Public Beta. Neigther from a USB-Installer or a internal SSD with preextracted HS Beta
@Milsabor: do you have HighSierra running? Can i get a copy of your DSDT?
thx
