are you absolutely sure you are attached to the non-intel controller ports? what if you move them around?
i haven't dl'd the turbo manual yet, but hopefuolly later i can dig into it some... i'd suggest you fool around on that "tools" menu to see what effect that has on the SI controller state.
or if you have ghosting skills, you can ghost to a pata drive, then boot to that, and turn the intel controoler to raid mode, then install your riad driver, then ghost back to the boot drive on the raid controller.
or find a way to get the raid driver installed on your current boot drive somehow, which i think evasive was hinting at.
