The Linux distros listed are probably the only ones that Dell officially supports on that model, but just about any distro should work. I'd suggest downloading a Knoppix LiveCD from http://iso.linuxquestions.org
or another download site. A LiveCD will let you boot Linux without installing anything and you can check to see if all of your hardware is detected. Then you can go on and install the distro of your choice. All you should need to do is insert the first install CD for the distro you want in the CD drive and reboot. If the system is set to boot from CD the install process will start and you're on your way.
