As of now it boots Linux and MS-DOS.

It was originally called "FreeMWare" (a similar pun to XFree86's X386 mockery), but now it's the much more catchy "plex86", a nicer-looking pun.

What is it with that Kevin guy and puns? I mean, think about it, bochs, freemware, plex86?

(oh, and it's NOT an emulator! virtualization, people, it's native execution, is it that hard to comprehend? if I hear one more clueless slashbot ask about the difference between bochs and plex86, I'll shoot them)
