hi there i tried boot loading my Maga 2560 to day and after about a 1min it comes up with this;
avrdude: verification error, first mismatch at byte 0x1e000
0xff != 0x0d
avrdude: verification error; content mismatch
any ideas?

What do you mean by "bootloading".

i had a similar issue, and following the instructions to do a 'loop back test' linky sorted it, dont know how or why 
I think 0x1e000 is the first flash address in the boot area if the boot area is set to 16kB. Perhaps
the bootloader partition fuses are set wrongly? Are you set to the right board type BTW -
installing a bootloader using Arduino-as-ISP requires the board type set to the chip to
be bootloaded, not the Arduino running the ArduinoISP sketch.
