You will have to have an external USB floppy drive if you do not have an internal. You will have to determine from IBM website which driver you need. If you have the technical skills, you can slip stream the drivers into your XP OS disk. You should also check to ensure that IBM has drivers for all your other hardware, like Video, Audio, chipset, wired and wireless network interface etc.
