the raid controller detects the IDE-HDD by itself so you don't have to do anything. The point is, that you won't see any entry in the BIOS, but you can see the message from the raid controller during the boot sequence (at least it was the case with my system). So don't bother about BIOS entries. The only problem is that you cannot connect more than 2 IDE devices with the controller (only one DVD-drive and one HDD or similar constellations)
