Hi Haza,
Thanks for the link to the article, I tried using the EFI from the article, but it still hangs on this lineHi Haza,
It should technically work (as we have sort of solved the AMD IGPU issue only very recently - check the 5800H threads here). I also have a build for my Atari VCS which uses a dual core AMD Ryzen APU which has successfully booted Big Sur and it has a Vega64 SSDT inside you could try. > https://www.tonymacx86.com/threads/guide-atari-vcs-2020-console.309903/
I put opencore 0.7.1 and also put the R7 240 card, but it still hangs on this lineOpenCore 0.7.1 or newer is required. Also you won't be able to install with the integrated Vega GPU on that CPU. You'll need a dedicated GPU.
yes, I did everything according to different instructions and reinstalled the patch several times, but it still hangs on this line, I can throw off the config.Did you setup the patches / quirk correctly? https://github.com/AMD-OSX/AMD_Vanilla#read-me-first
Using my EFI you need to manually enable the SSDT-Vega64 in ACPI and change the AMD GPU device properties to your R7 240. May also need the radpg=15 in the boot-arg.I put opencore 0.7.1 and also put the R7 240 card, but it still hangs on this line
And can you throw off these files for correction, I just don't have that much knowledge of opencore)Using my EFI you need to manually enable the SSDT-Vega64 in ACPI and change the AMD GPU device properties to your R7 240. May also need the radpg=15 in the boot-arg.
And if you run the installation on Vega 3 ? Will I need to make changes ?Using my EFI you need to manually enable the SSDT-Vega64 in ACPI and change the AMD GPU device properties to your R7 240. May also need the radpg=15 in the boot-arg.
I could help with this (if you aren't that experienced with OC). What is your device-id for the R7? You can find it typically under Windows Device Manager or Linux under Settings/Display/Property > Hardware IDs.And can you throw off these files for correction, I just don't have that much knowledge of opencore)
Not possible. It's a different set of ids. On AMD setups you must account for the correct installed card.And if you run the installation on Vega 3 ? Will I need to make changes ?
Thanks here is the id PCI \VEN_1002&DEV_6610&SUBSYS_04621043&REV_00I could help with this (if you aren't that experienced with OC). What is your device-id for the R7? You can find it typically under Windows Device Manager or Linux under Settings/Display/Property > Hardware IDs.

Thank you so much, I'll try it nowAlright @Haza
I have created an EFI for your chipset - hopefully it should work for Big Sur.
We don't need to enable the Vega64 SSDT as I am using a new alternative setting
and the card is set to your Vega 64 so it should work.
Thanks he stopped hanging on this line, but he now stops at memory panic.Alright @Haza

okeyAlright @Haza, I've checked the file made some more changes.
See if this works. >
