I had installed Vista on my ASUS P6T Deluxe V2 home built with an SLIC BIOS activation using: SLIC Tool v188.8.131.52 ASUS BIOS rom file Asus SLIC BIN file ASUS SLP file ASUS.XRM-MS file The Vista activation was good and held up to updates and SP1 installation. I have since uninstalled Vista. I didn't like it well enough to keep it. Now I'd like to give Win7 a try. Will this present BIOS configuration work for the activation of Windows 7 also, or do I need to start over again to be able to do an OEM activation?
