Intel HD 630 Black Screen

[naquaada]

Hello,

 

I have a Asus Prime 270-K with an Intel i7 7700. The SMBIOS in OpenCore is set to iMacPro1,1.

Sonoma is working well, the CPU name is shown. But I have a few remaining problems.

 

- No NVME devices listed, NVME SSDs are shown as SATA

- Black Screen after Sleep

- Only HDMI is working

 

I searched lots of topics, but the most of them are very old. So many infos but nothing worked.

I'm also afraid that the lots of patches I added are resulting in conflicts.

 

After patching the framebuffer I got heavy graphics errors, but two different screens on DVI and HDMI.

The DVI screen is in 4:3 format. It is the mainboards primary port, because the image on the HDMI screen

is stretched. The last port is VGA. The video mem size ist set to 128 MB.

 

I added my EFI folder. Any help is appreciated.

 

Greets, naquaada.

With IGPU need to use iMac18,1 or iMac18,3 smbios. Use iMacPro1,1 or MacPro7,1 only with AMD GPU for good hardware accel h264/hevc

I can only boot with the model types iMacPro1,1. I tested iMac17.1, iMac18.1, iMac18,2 and iMac 18,3.

It's immediately stopping at the black Apple stop sign screen.

 

Can you check the config file? I guess the problem is wrong configuration. The boot-args are

-v dart=0 darkwake=0 forceRenderStandby=0 igfxmpc=1 igfxonln=1 alcid=52 watchdog=0 agdpmod=vit9696 keepsyms=1 swd_panic=1

I guess there also too much entries. Alcid=52 is the correct layout id for this board.

What about the csr-active-config? I have FF0F0000 now.

And why are NVME devices listed as SATA? I never found infos about that.
