hi everyone, I'm new to this forum, I have a problem to configure Wisky lake UHD 620, 0x3EA0 I'm using Opencore ... I'm running different tests but nothing always shows me 7 MB the bios has no configuration, memory and video .. .
the settings I put are these:

PciRoot(0x0)/Pci(0x2,0x0)
AAPL,ig-platform-id Data 1234568
device-id Data A53E0000
framebuffer-patch-enable Data 01000000
framebuffer-stolenmem Data 00003001
framebuffer-fbmem. Data 00009000

I see this writing before catalina starts:

[IGPU] Graphics driver failed to load: could not register with Framebuffer driver!

Catalina works but I always see 7MB so without acceleration :cry:

I don't know what else to try, could any of you give me some advice? I'm going crazy :banghead:

Thank you

Try:

ig-platform-id = 00009b3e
device-id = 9b3e0000

i tried it gives me black screen... :cry:

on the WhateverGreen website I recommend this
For UHD620 (Whiskey Lake) fake device-id A53E0000 for IGPU.
WhiskeyLake

I use 3e9b0000 with my i5-8265u with UHD 620... Not sure why it's not working for you... But I did not use "stolenmem". I set 64MB to DVMT-prealloc in BIOS.

Hi everyone, today I ran some tests (I am attaching the images to make me understand better)

with this setting I no longer see the word

"[IGPU] Graphics driver failed to load: could not register with Framebuffer driver!"

the message is different only that I get the black screen, and I managed to make the screeshot because I have memorized the movements of the mouse and keyboard ...

in the third screenshot the video card is not really detected in fact I have a black screen .... could someone give me some indication?

thank you

I also tried:

ig-platform-id = 00009b3e
device-id = 9b3e0000

I get the same result

as your nvidia is not supported on Catalina, assuming you are using your intel graphics?

if so then please update your hardware profile:
