Look at an Arduino board. They have a 6 pin header connected to certain pins on the processor for ISP.

Do that. LOOK AT WHERE THE 6 PIN HEADER IS CONNECTED. THAT is how you do generic ISP.

If it was once in an arduino, connect the RX, TX, V+, and GND pins from the chip to the same pins on the arduino board. You plug the board into the computer and upload a program just like you usually would.
