    I am working on Intel ICH6300 Watchdog timer. Watchdog timer by itself
    presents itself as a PCI function, but it does not have the interrupt
    line/pin register. Datasheet says it is hard coded to IRQ 10. I have written
    a WDM PCI driver for it. But how to I register the hard coded IRQ with the
    WDM framework, since the resource list does not have an entry for it.

    How did you claim this device in your INF file? Didn't the operating
    system already claim it in machine.inf?

    You can try adding a LogConfig section in your INF file.

    I found that even though there is a machine.inf file, there was no driver
    loaded for it. That's what it looked like. I disabled the device and it did
    not cause any problems to the system. I used the device properties window,
    and updated the driver for it by using a new inf file.I will look into the
    LogConfig section of the inf file. Thanks for the information.
