This will sound as an newbie question and it is, I'm sorry for that. As I'm "new" to the Win7 scene in light of activation, loaders etc. I'm trying to find what my perfect way of activating Windows 7 is on my machines. All my machines are HP (dc7100, dc7900) and installation of Windows7 was easy. I tested the activation with 7loader en RemoveWAT 1.4 and no problems there. Because I read about modded Bios, SLIC in Bios I looked to find understandable info on what is what. I hope that someone here can explain to me what is mentioned with Bios 2.1 and SLIC in Bios. Thanks in advance (please be gentile )
