installing sata drivers through ris

I am a system admin running 2003 server and pushing images out to clients everything goes well until I get a sata hd machine and I dont know how to have them install. I looked at microsoft website and seen the article about installing textmode drivers and followed it and still seems to not work. Can someone break this down to simple terms for me or show me the setup that I am to put in the sif file to make these systems work.
