Gigabyte Z390 M Gaming build with working NVRAM

[Valensing]

@pastrychef
I disabled Cfg Lock in bios but is not needed for OpenCore
You can enable NvRam in config.plist "AppleCpuPmCfgLock" && "AppleXcpmCfgLock"

I don't need "DisableIoMapper" for ignore vt-d, so you can remove dart=0 for clover I thinks

I test SSDT-SBUS-MCHC.aml but sleep not work

I consider those two quirks as workarounds. I don't have to use workarounds if MSR is unlocked.

I have never needed to disable VT-x or VT-d in BIOS or config.plist on any of my hacks.

I think think any real recent Macs have MCHC.

SSDT-SBUS-MCHC.aml and sleep work with AppleCpuPmCfgLock, AppleXcpmCfgLock
But just now no real Cfg ahah

With latest update (10.15.5) i have a black screen after booting.
macOS is clearly booted because i can hear sounds in background but monitor is off. Until this update i didn't have issues with monitor.

I'm using OC 0.5.8 with iMac19,1 sysdef and onboard gpu (latest oc efi from first post and with connectors patch).
System spec:
Gigabyte Z390M Gaming (F9g bios)
i5 9600k
Corsair Venegance LPX 16Gb (2x8Gb) 3000Mhz
Samsung 860 EVO 500Gb
Monitor is Dell U2212HM and is connected to DVI port.

Efi is attached to post.

Please try this config.plist.

Remember to set IGPU RAM to at least 64MB in BIOS.

Still no luck. BIOS settings:
DVMT Pre-allocated: 256MB
DVMT Total gfx mem: 256MB
Aperture size 256MB
Above 4G decoding enabled

Hmm... Can you try redoing the port patches using Hackintool?

With 32MB i get kernel panic.

I can, but first I would need to restore pre-updated version to enable screen sharing, then update again and connect with VNC to redo patches.

@pastrychef: it's minor problem, I think, but really frustrating... after upgrading "our" mainboard to version 9G (I was at older version till this time, updated because you recommended that) BIOS it's switching ... to French language every time I shut down the computer
Gigabyte support only gave me one solution: to remove battery from the main board and reset BIOS... Of course, it didn't helped at all. Any clue what might causing this? Did you encounter similar problem?
