Need help with Hard drive connection

My hard drive crashed and I installed a new drive as primary. What I would like to do is install the old drive as secondary. My controller cable under the old setting (with one hard drive) was set as hard drive to cd-Rom. And second controller cable as mother board to floppy only. How do I set up my system with two hard drives and two other drives (meaning cd & floppy)?
Plz help.
