 ## Versions of the Bootloader
 There are different versions of the bootloader - both in order to work on different hardware and because it has changed over time.

 This setup has other implications. When the Duemilanove is connected to either a computer running Mac OS X or Linux, it resets each time a connection is made to it from software (via USB). For the following half-second or so, the bootloader is running on the Duemilanove. While it is programmed to ignore malformed data (i.e. anything besides an upload of new code), it will intercept the first few bytes of data sent to the board after a connection is opened. If a sketch running on the board receives one-time configuration or other data when it first starts, make sure that the software with which it communicates waits a second after opening the connection and before sending this data.
 
-The Duemilanove contains a trace that can be cut to disable the auto-reset. The pads on either side of the trace can be soldered together to re-enable it. It's labeled "RESET-EN". You may also be able to disable the auto-reset by connecting a 110 ohm resistor from 5V to the reset line; see [this forum thread](http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1213719666/all) for details.

 The ATmega8U2 firmware source code is available [in the Arduino repository](http://github.com/arduino/Arduino/tree/master/hardware/arduino/firmwares/). The ATmega8U2 is loaded with a DFU bootloader, which can be activated by:
 
 * On Rev1 boards: connecting the solder jumper on the back of the board (near the map of Italy) and then resetting the 8U2.
-* On Rev2 or later boards: there is a resistor that pulling the 8U2/16U2 HWB line to ground, making it easier to put into DFU mode. You can then use [Atmel's FLIP software](http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3886) (Windows) or the [DFU programmer](http://dfu-programmer.sourceforge.net/) (Mac OS X and Linux) to load a new firmware.

 ### Automatic (Software) Reset
 
 Rather then requiring a physical press of the reset button before an upload, the Arduino MEGA ADK is designed in a way that allows it to be reset by software running on a connected computer. One of the hardware flow control lines (DTR) of the ATmega8U2 is connected to the reset line of the ATmega2560 via a 100 nanofarad capacitor. When this line is asserted (taken low), the reset line drops long enough to reset the chip. The Arduino software uses this capability to allow you to upload code by simply pressing the upload button in the Arduino environment. This means that the bootloader can have a shorter timeout, as the lowering of DTR can be well-coordinated with the start of the upload.
 
 This setup has other implications. When the MEGA ADK is connected to either a computer running Mac OS X or Linux, it resets each time a connection is made to it from software (via USB). For the following half-second or so, the bootloader is running on the MEGA ADK. While it is programmed to ignore malformed data (i.e. anything besides an upload of new code), it will intercept the first few bytes of data sent to the board after a connection is opened. If a sketch running on the board receives one-time configuration or other data when it first starts, make sure that the software with which it communicates waits a second after opening the connection and before sending this data.

If you ever accidentally remove files used by the explore sketches, you can copy them over from the SDcontent directory found in the robot library. Alternatively you can [download the files here](/en/uploads/Guide/sdContent.zip).
