You definately need a driver disk to install XP (other than your restore CD). It is all correct as you say. One hard drive does not make a RAID - if you had 2 SATA drives in your PC then you could change the BIOS setting to enable RAID 0 or 1.
But for now forget all about RAID, its not important for what you have. You'll need to go the motherboards manufaturers website or your PC manufacturers website and get the SATA driver for installing XP.
