I am using Big Sur 11.1 with bios 1.3.1 and open core 0.6.4 with UEFI booting.
have used slipanot EFI with little modification, remove edid patch and add -igfxmpc in boot argument and latest version of WG kext. for combo jack to work add alcdelay=1000 and alcverbs=1 to boot argument.
slipanot Can you please tell the process of installing Big Sur. I tried to install Big Sur with your EFI, After selecting usb and select INSTALL FROM BIG SUR , I can see some text then a minute or two Screen goes black. Which version of BIOS you used and what are your settings. can you please...
Thanks @hut2016 for SSDT-PNLF.aml. I had also same problem after using your SSDT-PNLF.aml, I can adjust brightness.
Brightness is not saved upon reboot.
I have EmuVariableUefi-64.efi and install rc scripts.
any suggestions for this problem and others.
