Some progress today. Using the iMac 19,2 SMBIOS (which also uses the i3-8100) in combination with the framebuffer for the H370M-D3H the DVI port is now fully working with acceleration. The HDMI port is active and kinda works - but the screen flashes and has a red interference. Suggestions...

I tried iMac 18.3 SMBIOS and still no change. I'll try with that SMBIOS and with the different framebuffers again to test. Something I have found that may be relevant is when I select Multibeast > customise > graphics configuration > intel HD 630 (coffee lake) - Multibeast fails. Unfortunately...

I went with macmini smbios because I thought it closest to my hardware. I have attempted the framebuffer patching from the framebuffer patching guide with the results in my first post. I will try again following your suggestions. Thanks.

Hi attempted boot with Clover > options > graphics injector > injectIntel (unchecked) No change

Thanks for your reply. I checked and adjusted the BIOS gfx settings: peripherals > initial display output > IGFX chipset > > internal graphics > enabled > DVMT pre-allocated > 64M >DVMT total gfx-mem > 256M > super-io > disabled (serial ports) Still turns off display midway through boot. I...

Hi, I've been trying to fix this problem for some time of the screen turning off without any success yet. I would like to use the DVI video output. I understand that people with very similar setups have gotten the video working. The system is a Gigabyte B360M-D3H motherboard with Intel i3-8100...

Hi pastrychef, Yes entering "nvram -p" does show SystemAudioVolume so it appears nvram is working. Thanks for your help.

Hi pastrychef, I muted in system preferences and rebooted and the setting did stick. So this confirms NVRAM emulation is in fact working properly?

I did a fresh install and executed the 'HelloWorld' test and it seems that my board does not support native NVRAM. I then ran UEFI + Emulated NVRAM install in MultiBeast. I tested again and the 'HelloWorld' test still fails as it seems the TestVar still does not stick. Have I missed something...

Thanks, I saw that thread and was wondering about "SSDT-PMC.aml". I saw no official response to this suggestion so was unsure whether this was the way to go or not? Thanks

Hi, I'm installing Catalina on the System (Gigabyte B360M-D3H) in my profile. How do I determine whether the board supports native NVRAM or requires emulated NVRAM? Thanks.

After updating the bios yesterday, today I reset the bios settings to optimised defaults and redid the cofiguration which solved the boot problem and the install went smoothly. I was able to configure everything except CFG-Lock and Secure Boot Mode which I was unable to find in the Bios Settings.

Today I tested several different Motherboard BIOS. It was F12 and I tried all releases up to the latest F14c. None solved the problem. I checked the Firmware version for the 970 EVO ssd and it is the latest 2B2QEXE7. The ACPI errors here look to be the culprit. I have installed SSDT-EC.aml...

Hi, I installed SSDT-EC.aml -> volume/EFI/CLOVER/ACPI/patched on the USB Installer drive but it still stalls. I notice the line: "AppleNVMe Assert failed ..." Could this be the issue? Are there any other suggestions? Thanks.

Thanks Pilgrim, I will pursue this and report back.
