# Size of boot loader section.
#   You may need to adjust this for:
#   atmega8 and 88 with 512 word boot section it shall be 0x01C00.
#   atmega8 and 88 with 1024 word boot section its probably  0x01800 (I have not tested this)
#   atmega168 with 512 word boot section it shall be 0x03C00
#   atmega168 with 1024 word boot section its probably  0x03800 (I have not tested this)
# This must match the fuse bits you set, see avrdude_usb_atmega168.txt
