Hi Felix, I bought a laptop of the company Tuxedo where I can disable IME. The options were really tricky. Difficult. I will check again, if they enabled it again. Hopefully not. I didn´t install any proprietary in the beginning. But I don´t know, and that´s why my question, if on my laptop is something installed beforehand. I don´t have enough knowledge about boot process etc. I assume Shepherd is the Guix init system like systemd in other linux distros. Is that right? What is Grub? Is EFI a part of Grub? I guess Guix community replaced "EFI" with "grubx64.efi" that´s why we can find this file in the boot/EFI folder. > Booring often requires proprietary firmware blobs What do you mean by "Booring" I don´t understand this word?
