Question : Downdrage from Vista to XP on Satallite P200?

I bought a new Toshiba Satellite with Xp Home premium and its giving me fits on my SBS2003 server.

I want to downgrade this to xp pro, I bought a new XP pro, but the laptop does recognize the drives in the  bios.  

My question is, can this be done? Do I have to do it once Vista is running, like from my desktop?

I guess the drive is SATA, so you will need the sata controller driver to support it. During installation, press F6 to install driver so installation can pick up the drive and continue.
