Possible to enable ACPI in Windows Server 2003

    Hi,

    I (quite stupidly) installed Windows Server 2003 that had ACPI disabled
    in the BIOS. I was wondering if, with Windows Server 2003, is there any
    way to enable ACPI after the installation.

    I've tried just enabling ACPI in the BIOS, and I see ACPI appear in the
    boot display with IRQ 9, but Windows doesn't seem to notice this.

    I know that with other Windows versions, this was not possible, but I
    just was wondering/hoping that there might be some way to do this in
    Windows Server 2003, rather than having to do a complete new
    installation.

    Thanks in advance,
    Jim

    Hi,

    No one has responded to my post, but just for the record, and in case
    anyone ever runs across this in the future...

    I think that I was able to accomplish this (convert non-ACPI Win2K3 to
    ACPI Win2K3) tonight.

    I did a bit of searching, and found the MS article at:

    http://support.microsoft.com/kb/q237556/

    About 1/3 down that page, it says:

    The optimum method to change from an ACPI HAL to a Standard HAL is to
    re-install Windows 2000 as an upgrade:

    1. Start Windows 2000 Setup as an upgrade.
    2. To automatically disable ACPI support and allow Windows 2000 to
    detect automatically or manually change and install the correct
    (Standard HAL) computer type that your computer supports, use either of
    the following methods:

    • To Auto detect the computer type:
    Press F7 when Setup generates the following informational message:
    Press F6 if you need to install a third party SCSI or RAID driver.
    NOTE: You do not receive a visual indicator that auto detection is
    taking place when you press F7; proceed normally with setup until it is
    completed.

    • To Manually Select your computer type:
    Press F5, and then manually choose the correct Standard computer type by
    using the following list:
    i386 source File Computer Type
    *hal.dll Compaq SystemPro Multiprocessor or 100% Compatible
    *halapic.dll MPS Uniprocessor PC
    *halapic.dll MPS Multiprocessor PC
    *hal.dll Standard PC
    *halborg.dll SGI mp


    The above excerpt talks about changing an ACPI HAL to a Standard HAL,
    but I had already imaged my system partition, so I figured that I'd give
    it a try, since I could simply restore my non-ACPI system if this
    procedure failed.

    So anyway, I first rebooted the system and enabled ACPI in the BIOS. I
    then did as the above excerpt suggested, using the "Manual" method,
    pressing F5 after booting from the Win2K3 CD. When the Win2K3 installer
    prompted for the configuration, I chose "ACPI Uniprocessor PC", and let
    it do it's thing.

    Once that was done, it rebooted the system, and I checked "Computer"
    under Device Manager, and that is now showing as "ACPI Uniprocessor PC",
    and now, when I shutdown, the system powers down completely instead of
    stopping at the screen telling you that it's safe to power down the
    system.
