Do manufacturers like dell, acer, and lenovo eventually include these SLIC 2.1 strings in their downloadable bioses? If I were a legitamate lenovo customer with the SLIC 2.1 string in my bios, and download & update to the latest bios from the lenovo website, what would happen to my SLIC string and activated win7? How is that different from using a modded bios and updating to a newer bios? Do you keep having to use modded bioses? If so, how do legit corp people with preinstalled/valided win7s upgrade their bios?
