In need of Setup Diagram of Moth.Board for XPS 720

Help! I just got this XPS 720 tower Second hand, its got the processor, about a gig of Ram, a Nvidia graphics card with a TV out, and 2 HD connections,, a soundblaster sound card, and 2 seagate SATA HDD's 1) 250GB and 1) 500GB, and a SATA CD/Rom. I want to put Windows XP Professional on it. My old computer is a Dell Diminsion 2400, so I am new to these SATA connections, and RAID configurations.  I have made many attempts to get the system up and running, to no avail, now I cant even get it to start booting up.  Is there any way I could get a diagram showing me PRECISELY how to hook everything up to the motherboard, (someithing like.... "Plug the data connection of you SATA optical CD Rom drive into SATA 4 connection on your Motherboard.." I dont normally need my hand held, but this stuff is frustrating as heck, cause I cant get it going.  Please help. Thanks!!
