Thanks :-)

Finally it worked. The notebook is running and the BIOS is open. Thank you for your great support. I just sent you a donation via PayPal.

Thank you very much. I downloaded it and tried 2 times to program it. Unfortulately I had verification errors after a while, so the notebook was not running.
I will try again and let you know if if the BIOS works after a successful programming.
