On mojave 10.14 the cold boot bug doesn't exist

 

This release allows cold booting on Big Sur for cards that use AMDRadeonX4030HWLibs.kext

 

side effect is screen will blink a few times

 

working on it - I'll update this post with latest release

Thanks

Successed test on my R7 250 (0x66101002) on Big Sur with full qe/ci and metal support.

However, the model recongnized as HD7xxxx, and there is no DP audio output.

This must be the best card ever made !!

 

Working on latest ventura 13.3

 

- enable amfi_get_out_of_my_way=1 in OC

- install 1st  https://github.com/dortania/OpenCore-Legacy-Patcher

- move the attached kexts to OC/kexts

- set fakeid as in picture

 

update:

this release as the coldboot bug (reboot from windows to fix)

 

found a random bug here:

without amfi_get_out_of_my_way=1  the driver won't load

 

i'm happy to see this work in ventura but firefox opengl crashing is annoying... - i'm more happy in big sur atm

this patch "unlocks metal"

 

undefined8 amdMtl_Bronze_asicIDToFamilyInfo(uint param_1)
..

returning 2 works fine

find {0x81, 0xff, 0x1f, 0x69, 0x00, 0x00, 0x7f, 0x29, 0x8d, 0x8f, 0x80, 0x98, 0xff, 0xff, 0x81, 0xf9, 0xcc, 0x00, 0x00, 0x00, 0x77, 0x3d};
rep {0x81, 0xff, 0x1f, 0x69, 0x00, 0x00, 0xeB, 0x60, 0x8d, 0x8f, 0x80, 0x98, 0xff, 0xff, 0x81, 0xf9, 0xcc, 0x00, 0x00, 0x00, 0x77, 0x3d};

 

there are others patches related to PEM init
