beside raid mode, ahci mode also needs additional driver installed. i have try serveral ways to intergrate sata driver, such as unattend.txt modification as you or use of winnt.sif (http://unattended.msfn.org/unattended.xp/view/web/36/), but only end up with many useless disks. i only succeed by using nlite. first, get the driver you want and exact into .ini file if necessarily (execute .exe with command line -a -pc:\folder). and use driver intergration of nlite and choose the .ini file, check txt mode not pnp. burn it and install, that's what i do.
