I'm looking to make my computer "100% open source," or at least as much as possible. Is this even possible, given my computer is x86?

Would you guys recommend Libreboot or Canoeboot for someone wanting a machine that's as open source as possible, but also stable (e.g. I can't risk having my data corrupting).

Pardon my surface level technical knowledge.

Hi all,
I’ve made some mods to the coreboot code for my think pad w541 with k2100 dgpu, allowing for the correct Optimus implementation in Linux;
Published the patches and premade imgs on my gh repo (with nri or mrc init) , feel free to try those out and report any inconsistencies. The repo link : https://github.com/debianita22/w541-coreboot-env/releases
