Hello everyone, My laptop is Dell Studio 1537. I modded my bios to SLIC 2.1. Then, I use OpaTool 0.7 to install certificate & Windows 7 Ultimate key but failed, it still says that Windows is not activated. Please help me. Note: My OEMId table is "Dell M09". I read the topic "Win 7 & Server 08 R2 SLIC 2.1 Bin Collection" at here: http://forums.mydigitallife.net/threads/5952-Win-7-amp-Server-08-R2-SLIC-2.1-Bin-Collection. I don't understand about BIN file, I wonder that I missed the step to use Bin file? If yes, how to install Bin file? Thanks.
