I am trying to simply extract the BIOS .HDR or .ROM file out of the .exe file. The old method of adding -writehdrfile after the bios exe name no longer works for sandy bridge based dell laptops. Does anyone know how to extract the BIOS? I tried Universal BIOS backup toolkit, but the MSRs I wanted to change weren't even referred to at all in the BIOS, making me think that the BIOS extracted from the ROM chip was incomplete. Any help would be appreciated.
