Ok, I think I must to connect the 16MHz oscillator to my board in order to raise it from the dead. And then I will set the fuses for using 8 MHz internal oscillator such as I could remove 16 MHz oscillator, right?
If you want to use the internal oscillator, yes. In that case, set the board for a Lilypad, and "flash bootloader" -then the fuses are set for 8 MHz internal osc.
