Digital Pin Locations
Here is a image that shows the locations of digital pins for the j19 p1 p2 and p3 pin headers.
ArduinoISP Connection Diagram
Here is a connection diagram for wiring up an arduino to be used as an AVR ISP in order to program the bootloader.
To program the standard Arduino Bootloader select:
- Tools->Board->Mega 2560
- Tools->Programme:ArduinoISP
- Tools->Burn Bootloader
These bootloaders will allow larger firmware sizes than the Arduino Mega standard one:

Example avrdude commands are documented here: Rambo_development
