    Value added drivers for the AS4000 running Windows NT 3.51 can take 
    advantage of interrupts for the Correctable Error and the I2c Bus.
    These interrupts are made  visible to device drivers on the "Internal" 
    bus. A device driver may connect one of these interrupts via a call to
    HalGetInterruptVector().  The bus interrupt level/vector are defined 
    below for the Correctable Error, I2c Bus, and I2c Controller interrupts.  

    For example, to connect the I2c bus interrupt vector:

        HalGetInterruptVector(
            Internal,
            0,
            AS4000I2cBusInterruptVector,
            AS4000I2cBusInterruptVector,
            &Irql,
            &Affinity
            );

    See the Windows NT Network Developers CD for more information on
    the steps necessary to connect an interrupt service routine for
    kernel mode device drivers.
