Question : IDE / Sata Connections

I have an IDE connector type Hard Drive and Motherboard that has a single IDE output/input, the rest of connectors being SATA ( I have plenty of those).  As I have 2 IDE connections already taken by existing drivers, what do I need to connect another IDE device, Hard Drive. Is it possible to have more then 2 devices per IDE cable? If not, is there a converter or an add-on of some sort I need to get?

Answer : IDE / Sata Connections
