So you installed everything (all components) and it works fine? Shutdown should work once you have installed the netkas 9.2.0 kernel. If the netkas kernel is better in any way than the vanilla, use it (thats what I'm using). If it doesn't do anything for you, then you might as well use the vanilla kernel. If you get good benchmarks without AHCI mode, then thats great (I'm assuming that you installed the SATA driver then right?). That will shave a few seconds of your boot time, and you will be able to use both OS X and Windows in harmony without changing AHCI settings (cause XP doesn't support AHCI)
Yes like u said the shutdown issue is gone forevere, and i'm using ahci(no ,I haven't any win at the moment..), unfortunately the sleep isn't working anymore , so I'll take few mins for trying the vanilla one.About no ahci , do u think I could miss some performance on cpying large files ?
