Amazing discovery last night.. Vista64 died on me (some update failed).. so i though i'd install Windows 7. I installed ultimate RTM and skipped putting cdkey in I was going to try a loader. When it was installed i checked the bios with RW-Everything, noticed that slic had changed from 2.0 to 2.1 (hrm, now I'm wondering if its been updated for W7 as this laptop is in upgrade program) So I ran 7Loader 1.5 and told it I had slic in bios and installed ultimate certificate and latest dell key, and voila!... one ultimate install with no bios modding needed and no loader.
