I know this has probably been asked a lot of times before but i cant seem to find any helpful info. I have a GA-K8VT800 Pro board and have 2 hard drives, one sata one pata. I am running xp pro on the sata drive and when I installed the OS I had to install sata drivers with floppy disk. Now when I try to install vista onto the same drive, it firstly asks me for a cd/dvd rom driver. I mean.. wouldn't it already have a driver if it's reading from that drive? and also do I need to install any sata drivers? Thanks for your help
