Depends on your definition of "DOS" - do you want a MS-DOS-compatible system, or just one with the same appearance, or just any "disk operating system"? – grawity May 31 '10 at 18:31

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. See the FAQ for guidance on how to improve it.

Well, it's (arguably) 32bit, but definitely not 64bit... – sleske Jul 19 '10 at 7:57
