Updating/adding drivers to ghost image?

[HungryHippos]

Hi everyone

I have a question with regards to adding drivers into ghost image files

At work we use similar model machines, mostly Dell boxes. When we get a new model in I would like to be able to "slipstream" the drivers into my images.

I can use Ghost viewer to add files to the image but is it possible to add the relevant drivers in such a way that Vista will use them when it tries to install devices?

I have tried to slipstream in drivers via vLite but it gives me unsigned driver prompts near the end of the installation which I want to avoid

Thanks,
