    ACPI Issue!

    We're migration to Windows 2000 at my office and after doing about 30 of these, I forgot to turn ACPI on in th BIOS on my latest machine. So Windows saw it as a Standard PC and not an ACPI PC. Does anyone how to change that besides doing a reinstall?

    Thanks for the help!

    Well Tech net says not....

    Q24236 How to Upgrade Windows 2000 to Use an ACPI HAL looked very promising until I read it.....

    You cannot change between Standard and ACPI HALs because of the different way an ACPI and a non-ACPI BIOS enumerate hardware. The copy of the hardware tree, which is kept in the registry, is stored differently for each type of HAL. If you change the HAL without running Setup again, Windows may not be able to find hardware components needed to start the computer.
    Mmmmm, 'ollocks!....

    Is this true? I can say I've tried it with xp & there you can just (mostly) change it & it seems to work. Sooooooo???

    These are fresh clean installs?? So try one & see, looks like you are watching setup 30 times otherwise....

    Try turning on ACPI in the bios, then changing to ACPI hal in device manager. The run the sysprep utility and reboot. All hardware will be redetected and I believe this will work.

    Lemme know!

    If your going to try the advice above, get the updated version of sysprep
