Dell Vista or XP oem and after market Motherboard in 630.
If you upgrade motherboards in the 630. And then do a clean install. Is there going to be a problem with Vista/XP? I ask because dell's XP/Vista oem will automatically install the keys when its see's a dell bios mobo.
So what happens down the road when people start buying new mobos. Will they all have to buy the os again.
If you install the os on the new non dell board, It will ask for a key.
It would be a pain in the rear to reinstall the old mobo to reformat the hd and clean install. Then put the newer mobo back in.
And before you say use ghost or something else to make a backup image. What if your hd fries or something.
