Does atmega 128 work with arduiino language, just reduced number of GPIO's compare to the 1280 or?
Its possible to connnect a usb to serial cable to the ICP header for communication or?
I got a board with just icp header and an atmega 128 which i would like to program by using the ardiuino IDE.
I will use STK500 to upload the bootloader to the board.

im interested in this too. anyone?
thank you

yupp its implemented in the new version of arduino enviroment
If you have an ISP programmer to connect to the 6 pin connector you need neither a bootloader nor a serial line nor USB nor whatever.
Just change the entry in your boards.txt file and that's it...
All this USB/bootloader schnick-schnack is meant to obsolete an ISP programmer (which BTW is a excellent idea, but should not hinder you in your work by becomming a philosophy)
i have this board here:
and i WANT to burn the arduino bootoader onto it and use it as i do with my duemillanove. burning the bootloader and the programms via ISP is ok for me. still possible?

So if you do want :
And of course you can! As with the "2009" there is nothing on a Mega board but a voltage regulator and a serial adapter.
Any USB/TTL break-out board (5 through 15 Euro) will work, also the 5V supplied by USB. Lookout what comes out for auto rest! Some have DTR some already a "reset pulse". In case of a level DTR, you need a cap to reset (around 10nF... 100 nF is still fine though oversized..)
