Help with SATA

[ability]

Today I powered on my new pc and started setting things up, although, I believe that I did not set up my hard drives the way they are supposed to be. I have two 74MB raptors and would like to put them on raid 0. But I had nothing but trouble when i tried to active the raid option in bios, so i continued installing windows normally. I don't see my second drive in windows, only my C: drive, and I don't know if they are set up on raid properly either, any help on this would be greatly appreciated.
