I have the same situation with you, I want to mod my 4930g's bios slic(original) from 2.0 to 2.1 in order to perfectly activate win7. Now what method do you have? If you have any good news, please inform me.
Could you please upload your RW report so I can check it? The mod should be okay since w7 is already succeed activated on bobamerez system... What type of lappy when you first buy it.. is it Non OS or came with vista?
