OK I understand you now....but I was thinking of another scenario......I was debating whether or not to put DOS on my other partition.....There are still alot of things I like to do using DOS. How would dual booting work with that? Should I install DOS first then Knoppix? And I would have to edit lilo also.....how would I go about inserting a reference to DOS so I could boot it? I dont really understand the MBR and how it works.
