<< Solved >> Can't boot Catalina on igpu (HD630) with Opencore

[Pumpk1in]

Dear Hackintosh Wizards,

You will find my EFI folder attached.
I just lost one full day trying everything I could find on Google to make it work but I have to admit, i'll never fix that by myself...

The problem is quite simple : I have a black screen, AKA "no signal" if I try to boot on the igpu of the 10700k.
My motherboard is a Z490 Gaming plus from MSI.

I have a GTX 1070, so I disabled it with the ssdt method. I also tried with the -wegnoegpu boot flag and also tried the DeviceProperties method. So it should be disabeld on MacOS. I just want to keep the 1070 available on Windows.

Then I enabled the igpu, or actually, I tried.
You'll find this, which is, I suppose, OK for my system. (pciroot verified in Windows device manager)

<key>PciRoot(0x0)/Pci(0x2,0x0)</key>
            <dict>
                <key>AAPL,ig-platform-id</key>
                <data>
                BwCbPg==
                </data>
                <key>framebuffer-patch-enable</key>
                <data>
                AQAAAA==
                </data>
            </dict>

With or without that DeviceProperties, the system halt at the same point, right after the "gIOScreenLockState" thing.
So it seems that I missed something big. But I don't know what.

I tried with different SMBios, iMacPro, iMac19,1, iMac19,2

Here is the screenshot : sorry it is blurry as from a video as the screen goes black right after that.


My screen is plugged to the DP output of the 1070 and is also plugged to the hdmi port of the motherboard. I also tried the DP output of the mobo, as I read that only DP or only HDMI could work. But no luck here.
In the BIOS igpu is enabled with 64mb setting. I tried with primary boot device on PEG and primary boot on igpu, same result.

Note that, I can boot without problem on the Nvidia card If I remove the ig-platform-id thing and the ssdt patch.

Any idea ?

Thanks a lot !

try removing your nvidia card

also try a smbios to match your processor

Hi, I alreayd tried multiple SMbios. No luck

I could try without the Nvidia card but as I want to keep it, I don't understand the process ?

at least try and remove it physically from the computer to give yourself a chance of making your hackintosh work

what multiple smbios's have you tried?

 

[Pumpk1in]

I tried iMacPro(don't remember the number behind), iMac19,1, iMac19,2

I already have a "chance of making it work", as it work very well if I boot on the Nvidia card.
But without acceleration as we all know.

I'll try without the card, you're right, as this is the only thing I did not tried.

iMac20,1 may work

also make sure your bios settings are correct
Disable

• Fast Boot
• Secure Boot
• Serial/COM Port
• Parallel Port
• VT-d (can be enabled if you set DisableIoMapper to YES)
• CSM
• Thunderbolt(For initial install, as Thunderbolt can cause issues if not setup correctly)
• Intel SGX
• Intel Platform Trust
• CFG Lock (MSR 0xE2 write protection)(This must be off, if you can't find the option then enable both AppleCpuPmCfgLock and AppleXcpmCfgLock under Kernel -> Quirks. Your hack will not boot with CFG-Lock enabled

Enable

• VT-x
• Above 4G decoding
• Hyper-Threading
• Execute Disable Bit
• EHCI/XHCI Hand-off
• OS type: Windows 8.1/10 UEFI Mode
• DVMT Pre-Allocated(iGPU Memory): 64MB
• SATA Mode: AHCI

I changed to iMac20,1
All of those settings seems to be OK in my bios. I just had to disable CFG-lock but it boot with that thing enabled, when on the Nvidia card. So I don't know if it is really mandatory. I tried to boot again : nope

I'll try another boot after removing the card.

your verbose image in post 1 relates to a graphic issue, check DVMT in bios is set to 64MB

 

[Pumpk1in]

Yep it is already on 64
But I switched back to PEG as primary boot device and now, the screen stay on the last line instead of going black.
(no signal on the mobo outputs) So I took a picture :

Ok, so I tried without the 1070 in the PCI slot and the system did not boot.
So, no doubt my opencore config is the problem. But I don't know where to start.

To talk about this hackintosh, it is running since MacOS 10.11. I was under Clover. Then I upgraded to 10.12 and 10.13.
I decided to migrate to Opencore and stay under 10.13 and it was running perfectly since months. So I decided to upgrade to 10.15 and sacrify the 1070. With no luck.

EDIT:
Ok, I tried to use a DP cable.
I was using a DP > hdmi cable.
And it worked, sort of. I am able to see the login screen. But as soon as I enter my password, the computer reboots.
EDIT2:
Well, after adding <key>enable-hdmi20</key> I tried with an hdmi cable and same result.
I can get to the login screen, but is restart after login.

Any idea ?

Thanks.
