Haswell/Big Sur Boot Loop Help Needed

I'm working on getting Big Sur running on a Haswell system with the following specifications:

• Motherboard: GA-Z97X-UD3H
• CPU: Core i5-4690K/Haswell with Intel HD Graphics 4600 iGPU

I could not get any self-generated SMBIOS's to work, so I am using the ones found here: https://github.com/trick77/OpenCore-ga-z97x-ud5h

I followed the OpenCore install guide, and made it to the installer. First reboot during install went ok, and with about 20 minutes left, it rebooted...
