I guess its possible, but could you flash the bios region only using software option? i would really like to help if you could dump your own bios region + able to flash it. the .bin for this bios region is about 6MB (Bios only), it’s UEFI but not ami uefi. Here i provide a clean bios for 7020 but added NVME + Samsung AHCI + Rebar DXEs, with bios codename SHARKBAY (check cpuz > mainboard to see if your’s the same). i also left the setup.txt for you to find which option does corresponds to above 4g since i could find it on uefitool but not on the ifr.
I dont know what a “Bios region” is , but the Bios it self is updateable atleast.
Well if i can find a tutorial here i sure should be able to do so. Ill check out this , this should work out. Ill try this tomorow after i install Windows on the machine (currently running Unraid only)
Thanks ill check tomorow and try flash
Nope in the a.txt file i couldnt find anything that would or could be the “above 4g decode” setting.
