Try high fuse set to 0xd9 (Atmega32). This sets the boot flash section
to the default. high fuse 0xdf leads to a too small boot section
size, and effectivly disables flash write operations (a !e should
work however).

Lock fuses leave as they are set from the factory. Always. Never ever
change them.
