M6700: Trouble installing High Sierra

[lamatta17]

Hi every body,

 

i have a Dell M6700 with AMD FirePro (ATI HD7870) and CPU i7, 3740QM, 2.7GHz.

i've tested everythink from this and other sites, to install High Sierra.

No luck. Boot from USB-Stick ends with a black screen after the apple.

Please give me a working EFI directory to try to install, so that i can optimize the system after installation.

Thanks

Hi Jake Lo,

 

thanks a lot for your Tipp.

Scusi for my long response time. I was ill.

This was the first procedure i have tried.

The M6700 there have a NVIDIA and a Intel VGA.

My aid have a AMD.

I think, this was the reason for the "black screen"

try lilu.kext and whatevergreen.kext you might have to add some boot flags for whatevergreen instructions would be on the source page readme.

OK, i have the Dell M6700 with AMD FirePro (ATI HD7870) AMD M6000 and CPU i7, 3740QM, 2.7GHz back.

The igpu was disabled by the AMD-Card. You can't see it in the BIOS and clover displays only one gpu, the AMD

i've install Mojave per UEFI and must boot with Lilu and WEG with radpg=15 flag.

 

My Problem is, i cant use the internal Display. Only the HDMI works.

Clover says the AMD is from Typ "Chutoro", with 5 Ports and connector 00000030

ROM name ist Cape Verde.rom

The M6700 have the int. Display, 1x VGA, 1x HDMI and 1x DP.

Please help me to switch to the int. Display.
