1. I tried today Catalina and OpenCore. This bootloader destroyed my nvram, now even if I reset nvram in clover, delete nvram on efi partition, my system boot with arguments from OC. I see Open Core in boot menu in bios. I didn’t install it on zbook. I install it on another laptop to prevent something like this ((((( need your help to restore nvram
1. I found solution to restore NVRAM
Actualy the problem was - the long migration of clover EFIs through different Hackintoshes, and thats why i was used emulated nvram. But when i booted OpenCore even with different OS, the OpenCore chanced real Variables and here somehow conflict begins, as laptop always was using emulated nvram.
The only method worked for me is this:
1. Delete nvram.plist
2. Terminal "sudo nvram -c"
3. Delete "EmuVariableUefi.efi"
4. Delete RC Scripts (location on img)
5. Replace (if used) "OsxAptioFixDrv.efi" by "AptioMemoryFix.efi"
6. Restart by
Hard Power Off
7. Clean NVRAM by pressing F11 in clover
8. Reset using Clover Icon
9. Press
F2 to generate bootlog in EFI>CLOVER>misc (To be sure nvram is not reading from plist)
10. Boot OSX and restart once more time.
11. Native NVRAM is working. No more emulations
@theroadw
How is your progress with WX4170?
2. I`ve looked G3 and G5 locigboard on the web and found 3 soldered simple hotplug detect mux chips "
PI3WVR12412". But its unnusual, as laptop has 4 outputs. So i think that signal to eDP from dGPU is tunneling by pci lanes. I don't have any other explanations.
But if we look closer on CPU balls. We will find Digital Display Interface Pins. And CPU has 3 DDI ports. So possibly DDI are connected to ports, But how
edp is connected? eDP directly connected to display.
