Hi guys, I've read all about the SLIC 2.1 loaders and bios mods but still have a question about my setup which I hope someone here can help me with: I have a shuttle barebones system. It has SLIC 2.0 BIOS, but obviously being barebones has no OEM cert. When I built this system I installed and activated a LEGIT copy of Vista HP x64 (OEM) Now I've dual booted with Win7. Currently using daz loader to activate. When booting I choose the "Windows without loader" when booting Vista since its already activated with a legit key. However I found a SLIC 2.1 bios mod on this forum for my system and would like to use it if possible for Win7 instead of the loader. But I'd like to know if this will cause problems with the Vista activation if it suddenly sees an OEM cert in the SLIC bios?
