You'll have to be a bit more specific:
Are you trying to create backup of your original XP install CD
OR
Are you trying to create a CD that'll install XP with all the subsequent Service Packs and Updates?
The former can probably be achieved through usual pirate methods. I can't help you, as I don't do piracy and in any case this forum prohibits discussing it even if I did know anything!
The latter requires you to create "slip-streamed" disk. I've seen it discussed on these forums, so do a search or Google for it.
