Why is my Raid array not showing up with Windows Xp Pro Reinstall

I recently Reformatted my main hard drive with windows xp pro due to previous problems with some software issues. During reinsatll I installed the drivers for RAID  and ATA during installation allw went well. when I got Windows loaded the drives which were set up from before as a Stripped 2+0 setup and unchanged during this process do not show up in the drives area under My Computer. All my data is on hese two drives so any help trying to fix this issue would be appreciated. They show up in the raid utility during bootup but do not show up in main boot screen where cdroms and master slave drives are listed during the POST boot process and do not show up once boot is complete however they do show up under system device manager but no drive assignments are listed.
OH My raid controller is onboard Promise one on a Gigabyte MB.

thanks for any help you can shed on this problem.
