You need to build a new image of the XP installation disk that contains

Those can be downloaded here : http://h20000.www2.hp.com/...

Once you have downloaded the file, extract it somewhere on your PC and make note of the location.

Then you'll need to follow this procedure to add the drivers to your original XP setup disk.

You'll need a tool called nLite to do that. Don't worry about adding sp3, you can simply add the driver (that's when you'll need to point to the folder where you extracted the file above).

At the end of the process you will have a new iso file that you need to burn. I'm using the new install CD I created as I speak and it seems to work.

Hope this helps and that it'll work for you too.
