Each nation has its own agreement with the USA that defines these things, it’s weird. I think it’s in Wisconsin where tribe members retain hunting and fishing rights to a lake sold as a private lake, when cops showed up, they had to let them fish and hunt or the land would be returned to the tribe. As per the agreement from long ago.
I’ve had luck with puppy Linux on 32-bit machines. I also got arch32 working on a few. Arch is a steepper learning curve as the arch-install script doesn’t work on 32. Related there’s quite a group keeping parabola working on all manner of systems including 32, if libre is more your style.
