this list is of os's is not just a list of os's which fully function, but also os's which partially work to lesser or greater degree, and some os's work well still or used to work..but are incurrent disrepair and need work, are simply mentioned, referred to, or individual work has been done concerning them with the n8x0 ...
keep all that in mind.
there is a folder (somewhere around here) with I believe...browser bookmarks for easy reference instead of hunting for hours on end...
