[En-Nut-Discussion] Lock bits reset

[Radek Podgorny]

Thanks for the advice... I think this is the real problem here (disabled 
internal clock). I was going to try the method you've described in the FAQ 
but I failed to find the pin for that XTAL1. Is it available somewhere on the 
Ethernut board? I hope it is, cause i really dont want to connect anything to 
those tiny pins on the processor itself... :-(

Thanks...
Radek
