Hi all, My current set-up is MSI mobo and P4 3.0E with newly XP-installed harddrive. My question is if I run my old harddrive, which I used with ECS board, with my new MSI board, will the old OS and programs run without any errors? Or will the old drive and OS will corrupt? Or is it that if I stall MSI's drivers(like sound driver, I can't think of any other drivers for motherboard besides BIOS) on old HDD, I can run my old OS and programs without a problem? I am really waiting for the replies from you guys, thanks?
