KazuDante Posted September 3, 2023 Author Share Posted September 3, 2023 that config was janked , found it at random and it was from a diff laptop that had a dgpu i think an rx470 (something like that ) and it worked on big sur but what it did was i guess spoofed my native kbl to a skylake and spoofed it to use kbl drivers , using same config on ventura and up does not work . So now im going back to trying to make it work properly . this is my laptop https://support.hp.com/ee-en/document/c05392764 Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted September 3, 2023 Moderators Share Posted September 3, 2023 Is your display 4K? Can you set DVMT to 128MB? I remember there's a setting in my HP Elitebook with HD520, I can set it but mine is only 1080p display. Under Built-In Device Options in the BIOS set Video memory size 128MB if you can, make sure to disable framebuffer-stolenmem and framebuffer-fbmem in config file Link to comment Share on other sites More sharing options...
KazuDante Posted September 3, 2023 Author Share Posted September 3, 2023 sadly for me my bios is locked , cant change anything important . also tried to re-direct con2 to con0 and still blackscreen with backlight on , even tho i added backlight-register-alternative-fix thats meant for kbl. i seriously dont understand why this is so difficult when other HD620 users are already up and running fine Link to comment Share on other sites More sharing options...
KazuDante Posted September 9, 2023 Author Share Posted September 9, 2023 (edited) went back to win11 to check on something , does this mean that my laptop's DVMT is preset to 128MB and not 32-64-96 ? if so should i remove fbmem and stolen-mem ?

KazuDante Posted September 10, 2023 Author Share Posted September 10, 2023 @Hervé thank you , seems like i might be getting closer , i removed fbmem and only set stolen-mem , set it to about 30mb. rebooted , reset nvram but still got to backlight and black screen. many attempts at adding other tweaks like backlight fix backlight-alternatie-fix ... nothing still a blackscreen with backlight on . Then i looked at hackintosh tool since my only need is internal display i only set con0 in config but tried something ( just testing ) i also set the connectors always connected to change the flags , copied over reaults of the alldat to con0. when rebooted and test ( after reseting vnram ) verbose loaded as normal until it gotten to the IGPU part then about less then 20 lines after the backlight dimmed slightly as if it was about to ouput a display . so thats a step foward. Now even after reading busID patching im still confused . what i want to test out is to re-route for example con2'ouput to con0 so im asking whats need to be swapped to do that ?

Administrators Hervé Posted September 10, 2023 Administrators Share Posted September 10, 2023 You cannot "re-route" the output of one connector to another. Connectors correspond to physical video output ports. You can only patch the attributes/settings of connectors, that's all. Why don't try booting your macOS installation, without the framebuffer memory patches, from a USB key ? All you need to do is install/copy your bootloader and existing bootloader's settings on the key, then adjust the config on it to remove stolenmem/fbmem patches.

KazuDante Posted September 10, 2023 Author Share Posted September 10, 2023 @Hervé Mac is already installed on the laptop , i am trying to get graphic acceleration working so that the UI can run smoothly, that is my only issue for months Link to comment Share on other sites More sharing options...

KazuDante Posted September 10, 2023 Author Share Posted September 10, 2023 @Hervé my bad i misread it , thats what ive been doing to test configurations to find what would get acceleration working , i had already tried a minimal setup with no fbmem and no stolenmem , just the unified , at one point even tried just the AAPL-ig-platform of 00001659 then 09001659 , all those always end with a blacks screen with backlight on Link to comment Share on other sites More sharing options...
