from where can i get them?.
P.S. : i looked at my boards chip it says its a ATmega328p. is it same as 16u2?
or i need to do something else for that?

The ATMega328p is the main microcontroller, the one your sketch gets uploaded to. It has nothing to do with DFU mode, all it knows is what comes down the serial line.

The 16u2 is used as a serial adapter under normal circumstances; it's the one located near the USB port.

The DFU drivers come from Atmel - It sounds like people normally pull them from Atmel's FLIP tool, which includes them.
