NBRT with RAID Drivers

I used NBRT (v 4.1.0.15) to create CDs, for my two Win7 PCs and my WinXP PC.  The ones for the Win7 PCs appear to work fine.  The XP PC has RAID0.  When I ran the wizard, I added the XP RAID drivers by pointing to a folder that contains them.  But when I boot the XP (RAID0) PC, I can't find the C: drive (using command line).  Is there something else I need to do (perhaps while booting from the NBRT CD)?
