Module Name:

    pciintrf.h

Abstract:

    Contains interface GUIDs and structures for non-wdm modules that
    interface directly with the PCI driver via the PNP QUERY_INTERFACE
    mechanism.

Routine Description:

    Controls the enabling and disabling of native mode PCI IDE controllers
    IoSpaceEnable bits which on some controllers (currently Intel ICH3)
    will mask off interrupt generation and this prevent the system from 
    crashing...
    
    This should be called during AddDevice and the calling it modifies 
    PCIs behaviour to not enable IO space during START_DEVICE for the device.
    This function the allows the requester to enable IO space when appropriate.
   
    
Arguments:

    Context - Context from the PCI_NATIVE_IDE_INTERFACE
    
    Enable - If TRUE then set the IoSpaceEnable bit in the command register,
             otherwise disable it.


Return Value:

    None - if this operation fails we have aleady bugchecked in the PCI driver
