Re-write Arduino bootloader
If you couldn't load the bootloader via the Arduino IDE with the parallel programmer from the Arduino
website. Then you can used the following method to Re-write the bootloader on your chip.

FT232RL BitBang Mode AVR-Writer
FT232RL is an USB-Serial bridge on an Arduino Dicimila/NG/Duemilanove PCB. It has the function to
manipulate each signal pin directly. It's called BitBang Mode.
If we use "avrdude-serjtag" we can burn the bootloader by Diecimila itself.
This section describe the method on Windows-XP.
Attention!!!
If you want use "avrdude-serjtag" on Linux or Mac OS, you must remake ( patch, reconfigure and
recompile) it.
There are useful projects. avrdude by FT245R/FT232R(Linux) and BitBang Mode AVR-Writer on
Mac (Translated to English by Google.) These projects made a way to BitBang Mode AVR-Writer on
Linux and Mac !!!
Of course, if you use Windows in Vmware on your Linux or Mac OS, you can run
"avrdude-serjtag(windows version)".

Modify the Diecimila
There are four pads written as X3 near FT232RL on a Diecimila PCB. (These pads are connected to the
control pins of FT232RL.).Remove the solder of these pads and insert a pin-header. And soldering
it.Connect the pins of X3 and the pins of ICSP by wires. Please see the photograph below. (click to
