Hi Marcel, FC5_64 > Does anyone have the same board and got this to work ? I have ASUS A8N-VM motherboard with similar problem. At booting; ... ACPI:Unable to load the System Descrition Tables powernow-K8: MP system not suported by PSB BIOS Structure ..... Poweroff or 'shutdown -h now" won't power off the PC. I have been googling around and failed to find a solution. I suspect the problem accounting to BIOS. On the same PC runs WinXP on another HD and there is no problem on "power off" at exiting WinXP.
