Currently running an Abit ip35pro with mod bios and asus cert. Have downloaded bios mod to update to 2.1. My plan is to update my bios so I can then install and run Win7. My guess is when I update the bios, I will lose my asus activation on Vista64 and will have to reactivate with a Dell cert and key for Vista. At that point, my current Vista64 will be ok. Then I can install on a separate drive, Windows 7 and activate it by using the new Dell key for Win7. Is this correct or have I missed something? Thanks,
