[En-Nut-Discussion] Lock bits reset

[Harald Kipp]

No, JTAG is not required. On Windows, easiest way is AVRStudio.

Also uisp (Linux and Windows) can do that, you may check
the man page.

Be aware, that you may risk to disable the crystal clock
with wrong fuse settings. In that case check

P.S. There had been an answer posted from a non-subscriber
email address, but I'm afraid I accidently discarded it
instead of hitting confirm. Sorry about that.
