ammoune78 Posted June 25, 2023 Share Posted June 25, 2023 (edited) Hi, i have this laptop HP Pavilion 15" P208NK, that have this hardware: i7-5500U, Intel HD 5500 Graphics, Nvidia "GTX 840M" that i want to disable, so i can boot catalina. This is my current owned laptop, i don't know what things needed, but i'm managing now to disable this GFX0 "GTX840M" because until now, the laptop can't boot. Using OpenCore, i can't see someting, and it keeps rebooting, while using Clover at least, i can see the first lines of the verbose until it KP on \_SB.PCI0.RP05.PXSX. I'm attaching the extracted tables from Clover, so if anyone can help me fixing GPU disabling issue! Thanks Pavilion P208NK ACPI.zip Edited June 25, 2023 by ammoune78 Link to comment Share on other sites More sharing options...

I've tried that ssdt, but i'm not sure if i done it the right way! But are the HD 5500 needing graphics patch from the Properties for stolen-mem or something else? Because what i've seen in the last clover verbose, is that the iGPU past with error and then KP at the GFX0 path which is \_SB.PCI0.RP05.PXSX using that SSDT patch. Do i need to patch the Intel Brdwl Framebuffer? Link to comment Share on other sites More sharing options...
ammoune78 Posted June 28, 2023 Author Share Posted June 28, 2023 Problem solved, but using a weg arg in the igpu property! And my problem was in security=>SecureBootModel=Default, while the only working option is Disabled. If i set it to Default, it doesn't boot macOS at all.I'll make two guides for my Desktop and later this Laptop, to keep a trace on how did they worked and then upload them to My GitHub repository and share it!Sent from my Redmi Note 9S using Tapatalk Link to comment Share on other sites More sharing options...
