No the dell disk is just the same as a retail disk with the exception of some code to check the dell bios. no extra software. that is only on the factory restore partition   You can  use a retail disk but you cannot use the Dell key.
I would like to a clean install on my mini and would like to know how i should go about doing it. My problem is that i am unaware if the dell xp cd has all the same bloat ware on it and if so can i use my windows full xp installer cd with my mini serial number?
