Hi all. I'm going to be replacing a faulty motherboard with a identical model and revision. My old faulty motherboard originally had an modded BIOS that included the Dell v2.1 SLIC. And it worked great for Windows 7. I have been running Windows 8 Pro for a while now and was wondering if there is any advantage to flashing the BIOS of my replacement motherboard with the Dell v2.2 SLIC instead of v2.1? IF I decided to go back to Windows 7 would I still be able activate it against the Dell v2.2 SLIC / are the SLP OEM keys the same? Sorry if this has been asked before, I tried searching but could not seem to find a clear cut answer. Many thanks.
