load the Wiring's bootloader using Arduino as ISP

Hi all!
I'm building my own Wiring development board. Now i want to uploade into the AtMega128 the Wiring bootloader usinf the Arduino ISP.

In fact i have builded a new arduino board only to use as ISP.

I think that this programmer burns any Atmega from Arduino, it must be capable that burns other uP.

So the code for the AVRdude is this?

avrdude -c stk500V1 -p m128 -P com1 -b 19200 -D -V -U flash:w:WiringBootV1.hex -u -q

Where goes the fuses...i forget that detail!!.

Some other way to do this? build a fake Arduino CPU profile to burn it the bootloader?

Best Regards
Frank

The upload operation looks nice, i upload the HEX file without any error, but some is realy wrong with my uP or PCB, because i cant see any signal or voltage at the 16Mhz cristal. My CPU is an 128L..yeap is not so correct but is what i can found.

The LED conected at the PG0 keep always ON. The serial buffers and power reg looks nice, GND and VCC are all conected so i think is something wrong with the fuses SETUP.

I must keep reading about AVRDUDE FUSES to found where go them! :o
