Vista install

A question from a newbie so please bear with me. Currently running a pc with 2 scsi 80gb drives in raid 0 config using Sil 3112 sataraid controller, C drive on this config and running xp pro. Have a 3rd ide 80gb drive hooked in as well (x drive).

Went to install vista home premium on C drive, vista asks for the sataraid contoller driver to be installed, point vista to the folder where the drive is located but won't read it.

Question; can I format x drive and install vista on that, which doesn't seem a problem during the setup phase. After doing that how do I get rid of xp pro off c drive and then renaming x drive as c, which i guess is the common drive for the os.

Like I said, I am a newbie. If there is a simpler way to achieve this install then I would greatly appreciate the advice.
