It sounds to me you need to install the SATA drivers during the install (F6 Floppy).
If you do not have a floppy drive you can try to slipstream your XP disc and your Sata drivers to CD.
Here is how using Nlite:

Also be sure your BIOS is set properly for your RAID configuration.
Can you give me the exact model of this board?
Thanks,
