I'm wondering if anyone has tried the Sysprep solution that I outlined above? I would like to know if this works for anyone other than me. Maybe I didn't document it correctly? This has nothing to do with Microsoft doc 309283. It has everything to do with IRQ's as I previously stated. If you don't have the correct HAL on the machine you will never be able to properly deploy an image on a machine that has this hardware. Also, this Microsoft doc is not entirely correct when it talks about what HAL can be depoyed on what type of machine. What they are doing is covering their a**. You can really screw things up by changing the HAL to something that the hardware doesn't like. Just like modifying the registry. Microsoft shows you how to do, gives you the tools to do it, but will not be held resonsable when you screw it up. The same goes here. You either have to start with the correct HAL or change it to the correct HAL with Sysprep. Modifying the IRQ that the driver uses doesn't really help you create an image that works on all your target hardware. If you want to create an image that can be deployed on 99% of Dells, HP's, IBM, white box, desktop, notebook's you need to start with an "Advanced Configuration and Power Interface (ACPI)" and then change it, when needed, to an uplevel HAL like the "ACPI Uniprocessor PC".
