If so, reformat the hard drive and install it. But first make sure that you put your modem or Ethernet 9X driver on a floppy or Zip disk (Kudos if you got a CDR/CDRW drive to burn them to) before reformatting the system. Make sure that you also partition part of the hard drive for Linux.
Take the XP install disk and store it in a safe, dry place, you might need it to upgrade to a future version of Winders. :)
