Please note: When dealing with 3.5" drives there are TWO different controllers! The Apple 3.5" drive controller and the SuperDrive controller. The initial shipments of the SuperDrive controller are/were titled the 'Apple 3.5" drive controller, this was renamed to the SuperDrive controller to avoid confusion with the earlier product and for people to see that it is indeed a new product. One that has an IWM (342-0041) chip in the middle of the card and is labeled "Liron" on the back side. This is the original 3.5" card, also known as the Apple SmartPort card, it is the //c SmartPort on a card and can control external SmartPort hard disks as well. It does not contain firmware for 5.25" drives. The other has a lot of surface mount chips on it, and an LED on the top edge. This is the SuperDrive Controller Card.
