Pro Mini 328 16MHz: Which bootloader bits?


I need to re-flash the bootloader into some Pro Mini 328 16MHz boards. Which bootloader bits do I need? This is for a product so I need to get it right.


The Arduino IDE knows. Just connect the ISP, select Arduino Pro Mini (as if you were going to upload a sketch) and select Tools->Burn Bootloader. If you need to know which file, look in boards.txt: Pro or Pro Mini (5V, 16 MHz)

Allow me to clarify: I am attempting to use AVR Studio 4 and an AVRISP MKII to program because I cannot get the arduino ide to program with the AVRISP. I have located the folder with the bootloader bits but I am not sure which ones to use.
