When done bootloading, the status bar will be updated with the message "Done burning bootloader." Your chip is now ready to be programmer using the Arduino software! Congrats! Power cycle your Arduino and your new Atmega chip will be running a simple LED blink program with pin 13 (if this is not the case, try programming it with one). If this is working, it was most definitely a success.

>**NOTE:** On occasion, the process of bootloading an Atmega chip with the AVR ISP mkII will take an extraordinarily long period of time. Usually it should only take a couple minutes and in fact, the AVRtinyISP finishes much quicker. However, there are times where after 5-10 minutes it still appears to be bootloading. I found this to be an odd hiccup (perhaps it is triple checking the data flow) and after giving it ample time, 10 minutes or so, I usually unplug the programmer only to find the burning process to be a success and has ended long ago. I by no means endorse this method and you take all responsibility in whatever may happen to your chip, but in my experience it has been fairly harmless though you should proceed with caution. It is very possible that you may damage your chip in the process.
