I've downloaded the BIOS mod for the Asus P5E3. Flashed my Bios. Everything went well, tried several activation programs they all say that a SLIC 2.1 DELL QA09 bios is present. I install a dell OEM certificate and key.. And windows 7 x64 says it's not activated. I've tried different keys and certificates and it will not activate. When I check the Activation status with "SLIC toolkit v3.0" in the advanced tab under SLIC diagnostics it says SLIC status "invalidated" and by RSDT there is a red not equal sign (!=). By certificate and key it's a green sign with "cert. ok" What am I doing wrong?... or does this mean that the modded bios is not good? If anyone knows a solution please let me know..
