OK... I didt it. The modded bios was flashed correctly. Thanx for that. My only question is about the fact that the bios menus are the same as before. That is, no options to modify video dedicated memory and 7 x64 can still use only 3 of 4 GB of ram installed. Is that normal or, maybe, the modded bios was not really flashed? Thanx in advance for your help.
