Sorry that this isn't threaded as I subscribe to the digest only. We've actually worked with many support folks at Microsoft for over a year on a problem that covered this very issue. It arose because there is really no _good_ way to add new plug and play drivers to a standard build. The obvious solution would be to FIX sysprep so that it searches down a tree for new PnP drivers rather than having to explicitly define _each_ new driver directory (one cannot put all drivers in the same directory since some manufacturers may use the same name for an inf or driver file. Plus it becomes unmanageable). Since dev groups don't seem to talk to each other at MS, the search technology used elsewhere for PnP detection was not incorporated into sysprep. The most MS could do for us was to fix a couple of serious path length limitation bugs related to sysprep. (Sysprep is completely revamped in XP.) The other - less accceptable but still manageable - solution would be to allow users to manage their own .cab files and reference them in drvindex.inf. MS does not support this method and will not provide any information for doing so, even though they themselves do it for SP updates and obviously know how it can be done properly (and SP updates are more complex since it must also handle WFP). Nor do they allow modification of the original driver.cab file. (As an aside, there is a way to edit DosNet.inf to include a new .inf (to modify the DevicePath) and modify TxtSetup.INF (so the new .inf is executed) I don't know if MS now officially supports it, but they suggested it at one time. It didn't suit our needs since we are relying on clone/pnp rather than on unattended installs for our deployment methodology since it is much faster.) I'd be VERY interested if you can get this to work since nothing that MS has provided us indicates that it is feasible. jon ===== __________________________________________________ Do You Yahoo!?
