Hi Klem, Thanks for your comments, but I need some clarifications. "Whole bios dump 8 MB contains in first 2 MB: Descriptor, GBE, ME. Other 6MB it is Bios region." Does it mean that the whole bios is just a SIMPLE concatenation of the first 2MB + 6 MB Asus stock Bios ? Or during normal flash, the 6 MB Bios will be splitted into multiple parts and written into several region inside the 8 MB. "Sensitive settings (SLIC, MAC adresse, Serial Number ...) siting in 6 MB Bios" . Is this 6MB Bios = 6 MB Asus stock Bios ? If this is the case, all G75VW should have same MAC adresse, SLIC or serial/ServiceTag number I don't really understand. Could you please give me more details or if you have some tutorial how to reconstruct the bios, I would be very happy. Thank you
