Surface pro working sort of.....

Recommended Posts

So I managed to get open core up and running on my surface pro 6 

Currently using clover and it works but with the inevitable switch to open core and Big Sur i want to get ahead. 

I followed the guide form dortania and it seems that everything is working minus a few things :

Cant get the UHD 620 to work only shows 19 mb 

And battery indicator is not working at all. 

 

I am linking to the EFi folder I have used if anyone can share some insights.

Thanks in advance

So I followed a guide with clover and the steps are . 

Boot until you get to the desktop with 0x12345678 . 

Once you reach the desktop just rebuild cache and graphics should work. Natively. 

 

Let me get home and I'll try without a graphics patch with opencore .

Here is the link to the EFI folder that works with graphics acceleration in clover @MaLd0n

I am very new to opencore so can you just take a look and see what do I need to do . 

 

I think this might be related to this:

 

 

Upgrading from 10.14.6 to 10.15.1, the DVMT MinStolenMemory Patch was changed as below, so I tried to change it in Kernel and Kext Patches page in Clover Configurator. (Also pay attention that the MatchOS should be 10.15.x)

macOS 10.15 (19A602) DVMT MinStolenMemory Patch by FireWolfKabyLake:Find: 0F82A703 0000Repl: EB04A703 0000

And in the 10.15.4 update, DVMT MinStolenMemory Patch is changed again:

Name: com.apple.driver.AppleIntelKBLGraphicsFramebufferFind: 0F828F03 0000Repl: EB048F03 0000Comment: Disable minStolenSize less or equal fStolenMemorySize assertion, 10.15 (based on Austere.J patch by PMheart)

the original one on 10.14.4 and 10.14.6 is:

Find: 764648FF 05

Repl: EB4648FF 05

So I tried . 2 things 

Uploaded images

The first one got to a black screen with backlight working. 

 

The second one KP on com.apple.driver.AppleIntelKBLGraphicsFramebuffer

 

Can this be related to the patch I mentioned above ? 

 

More info on the log of open core don't know if I'm doing this right:
