Problems with hard drives and re-installing XP

[Devastat1on]

OK, i'm pretty sure you guys have probably heard this question: I want to re-install XP, I have a RAID 0 setup, it's a Dell XPS Gen3. So I go to the resource CD and get the driver and then reboot to CD....the screen comes up and i hit F6, select S to put in the files...they seem to load up there is IASTOR.cat, oem, sys, etc. and then it asked if there is anything else, I just hit ENTER to start the XP setup and then it says it still does not recognize the hard drives......I know the hard drives are there and works, but this F6 didn't work like I read it might....now, do i need something else other than these files??? I am pretty new at this stuff, so any help would be appreciated! Thank you
