Hello @Feartech I installed Big Sur release in my system (z97-hd3) using a USB pen drive and it went smoothly. The only issue so far is that the USB 3.1 ASmedia 2142 controller pcie card is not loaded and the USB 3.1 external disk is not recognized as such when connected. Attached are some pictures, ioreg, and my efi folder (excluding themes and docfolders). It seems that Apple has replaced Asmedia2142 by Asmedia3142 in some lines of the AppleUSBXHCIPCI kext plug-in located in IOUSBHOSTFAMILY. Maybe it's the reason why you've a problem with your card. Any tips will be highly appreciated.
