Does the first hazars_7_activator from august 2009 modyfi bios with slic 2.1 at the same way that the newest 7-loader 1.6 does?? I have the first on my desktop and the second on my laptop. Both system so far run fine. What is different with them?? Except from the oem brands and different keys?? And of course the first was only for ultimate.
No loader will modify the bios, they emulate the bios by loading the Slic table into memory. As you say one of the main differences is to activate more versions of Win 7. Daz has made changes to activate a greater percentage of machines and has added encryption to his loader. I think Hazar has dropped support for his loader to concentrate on his Remove-WAT method. There are two other loaders of note by HotCarl and Omdhar worth looking at. But if you are activated and running fine on both machines I would leave well alone.
