Please use code tags ( **\** button on the toolbar) when you post code or warning/error messages. The reason is that the forum software can interpret parts of your code as markup, leading to confusion, wasted time, and a reduced chance for you to get help with your problem. This will also make it easier to read your code and to copy it to the IDE or editor. If your browser doesn't show the posting toolbar then you can just manually add the code tags: `[code]``[color=blue]// your code is here[/color]``[/code]` Using code tags and other important information is explained in the [How to use this forum post](http://forum.arduino.cc/index.php/topic,148850.0.html). Please read it. You have Arduino Uno selected from the **Tools \> Board** menu but you say the target chip is ATmega8. The Arduino Uno is ATmega328P. Before running the Tools \> Burn Bootloader process you need to select the board that matches the configuration of your target chip. One possible option is to select **Tools \> Board \> Arduino NG** or older and then **Tools \> Processor \> ATmega8**. That requires a 16 MHz external clock. If I remember correctly, the Arduino AVR Boards package that comes with Arduino IDE 1.6.3 does not correctly support the ATmega8. You will need to update your Arduino IDE to a relatively recent version if you want to use that board selection. If you need a different hardware configuration I recommend MiniCore: > **[GitHub - MCUdude/MiniCore: Arduino hardware package for ATmega8, ATmega48,...](https://github.com/MCUdude/MiniCore)** > > Arduino hardware package for ATmega8, ATmega48, ATmega88, ATmega168, ATmega328 and ATmega328PB - GitHub - MCUdude/MiniCore: Arduino hardware package for ATmega8, ATmega48, ATmega88, ATmega168, ATme... which supports ATmega8 in all common hardware configurations. Now after all that I suspect this device signature 0xffffff indicates another problem as well but get started with the correct board selection first. ---

use this [arduinoisp](https://drive.google.com/file/d/1Kys4cWy_9f-7XupZiKvIQ7gcq5Rf9qdI/view?usp=sharing) code to arduino board and try again you will done. sorry for my english. ---
