Thanks a lot HardRom - you encourage me to make a second try with my M2N-SLI deluxe - coz first one failed when I tried hazard`s 10.6.2 - I was unable to boot DVD disk because my SATA DVD drive was connected to JMicron SATA port (no matter what mode it use). When I reconnected it to one of nvidia`s SATA port (as you did) everything works! Great job!
