I have a computer that originally had windows XP home edition installed on it. I have windows vista home premium installed on it now. I want to put a new, faster CPU into it, so looking into that I found that I need to update the BIOS. When I found the software download for the motherboard that is in my computer, it does not offer anything for vista. It does have one for XP. My question is, can I go ahead and download the BIOS update for the XP? Or will that be a big mistake?
