I got Hazzard 10.6.6i installed on GA-EP45-DS3 and everything works. Had little trouble with k.panic till I figure what I do wrong.Now its very stable and no k.p.Audio is external M-audio profire 610.Graphics GT-220 nvidia.8gb ram .I upgraded cubase 5 to cubase 6 to use it in 64bit mode but performance is very bad.Cubase 32bit works better.Still i have some problems when I want to change resolution.It stays blue and I have to push button to shut down and my bootloader is not full screen.Is it graphics or my monitor?
