Heya guys, I've flashed my BIOS with the posted P5B SLIC 1.2 modded BIOS, everything went ok. The post on this forum says it's a DELL. Now I added the dell certificate, but EVERY single product key I'm trying is invalid? This is Windows 7 Ultimate. If I check the status with OpaTool, I get "product key not found" in all three windows. If I try to add a key, I get "The Software Licensing service reported that the product key is invalid". What to do?? Thanks!
