I have updated my MP1,1 with Vista64 from Bootcamp2.1 drivers to Bootcamp 3.0 drivers by using the Bootcamp64.msi installer on the SL disk. I get a blue screen of death when the final drivers install after the desktop has come up. I have set graphics drivers to basic in safe mode which did not help. My system config is in my signature. Other than that I have my SATA driver set to AHCI. Of course that may be what 3.0 is messing up trying to force it back to legacy. I have no idea how I would prevent Bootcamp 3.0 to do this. For the time being I have gone back to a restoration point that I set before starting 3.0. Good ideas would be appreciated!
