I recall dual booting BeOS circa 1999/2000, on my 486dx2-66.
It was shockingly performant, especially with anything graphical.
The difficulty was no apps.
Brings back fond memories, nonetheless.
I really do need to play with Haiku more.
Now just combine it with Cosmoe[1] so you can run it from Linux too.
"Be" .... now that's a blast from the past! :-D
If only for the UI. Back then, all bring white and beige and Windows blue screenofdesthblye. Be OS was pure joy, if only to play around with. Many third-party developers (remember sharewsre) took s liking to the Be aesthetic and ran away with it.
