Burn bootloader with stk500

Hi all,

as i posted earlier, i am have problem with a programm loss and/or startup problems with the arduinoboard.

To protect the application loaded onto the atmega8, i thought to protect the application with a lockbit, and to set the brwonout option to 4V. After erasing the chip entriely, i wanted to burn a new bootloader on it. unfourtallay the burnbootloader does not work (programmer not responding). Burning the bootloader with a STK500 is not the probelm, but writing a new programm to the arduino board (programmer is not responding).

So my question is how to burn the arduinobootloader onto the atmega8 with the stk500 using highvoltage/parallel programming.
