@dodosoft - I am using Fedora.
Mine installed pretty fine, and is booting up just fine (I use KDE), I’m using a 32GB SER9 and my Fedora is fully updated.
My bios version is “SERT103”, it came from factory with that BIOS (showing a time of 10/28/2024).
I Tried to update the BIOS using a supplied BIOS update from beelink in February, but it turned out it was the same build and apparently “the latest”.
… Unless they have produced another BIOS version for a different memory size (please tell me that’s not the case!) then maybe the new BIOS could be at fault here?
I can try to help you through some debugging steps if you’d like?
