Boot from the XP CD... set your optical drive as a boot device in the BIOS (before your hard drive), insert the XP CD, and reboot. If you must install from DOS, don't run setup.exe... run winnt.exe. It's located in the i386 folder on your XP CD. Of course, if your XP CD says something like "Proprietary almost-XP CD: XP with ALL the cheese" on it, i.e., a restore CD, good luck in setting up the OS without the add-ons.
