A working DIY Mega2560 R3 is born

I just uploaded a simple skecth to my Mega processor. And it worked. I had some difficulties getting it working, I could not find all the sw and settings. So I list the links to them here to help people finding them.

I burnt them with AVR studio and AVRISP2, because that combination worked here.

I don't think we can all reach your C: drive, but thanks for the work you have put in.

No you wont but if you have a windows machine you can reach your own. I mean it is in Arduino directory already if you have installed it.

Thanks
