    ACPI Upgrade Workaround...

    Guys, I have a simple way to upgrade XP to Vista. Parallels is working on the fix, but until then here is all you need to do:

    1) Make sure you are using build 3150
    2) Set your Parallels OS to Vista
    3) Boot up to your XP SP2 OS
    4) From a CMD prompt, rename C:\Windows\System32\hal.dll to hal_std.dll
    5) From a CMD prompt, copy C:\Windows\ServicePackFiles\i386\halacpi.dll to C:\Windows\System32\hal.dll
    6) Uninstall Parallels Tools
    7) Reboot (XP may ask you to activate again - no need if you are upgrading to Vista)
    8) Let changes detect and complete (but cancel Found New Hardware), Reboot (again)
    8) Run Vista Setup/Upgrade Program
    9) Install Parallels Tools after Vista Upgrade is complete
    10) Kick-back and enjoy the wanna-be Mac OS called "Vista"
