Try starting Win7 with AHCI selected in BIOS to see if it will start. RAID here is likely used generically as multi-mode since you don't have mirrored drives, correct?
If Win7 won't start you can actually change it to AHCI mode using this tutorial IF XP will install in AHCI with the drivers you found or you can find XP AHCI drivers, so both OS's will be uniform: AHCI : Enable in Windows 7 / Vista
