Windows XP on but I do not have any of the drivers for it. It is a Gigabyte GA-EP45-UD3P and when I got the board it did not have a driver disk with it. It works fine running Windows7. But with XP I will need all the drivers including the sata drivers to put on a floppy for XP or it will not install. Is there anyone out there that can give me links for the drivers for this motherboard?
