Hi folks! Ok, this may wander a bit as I'm not exactly sure how the installation of Windows goes once you've slipstreamed the driver packs into them. The key problem is oempnpdriverspath, which in Windows XP can't be longer than 4096 bytes. Due to the excellent work of Bâshrat there are too many drivers. As when you run SMS OSD, you install Windows as per normal then install sysprep. You use an image generation CD which SMS provides which runs sysprep with the -reseal option and then you boot from to create the WIM image SMS uses to deploy Windows XP. Of course, you can give SMS a sysprep.inf file which has oempnpdriverspath defined in it. The problem I face is on this part as Microsoft says this: Specfically, the problem is that it adds %SystemDrive% to every entry in oempnpdriverspath. This will easily overflow the 4096 bytes I've got. From looking at the option 1 slipstream method, the winnt.sif file is used from the oempnpdriverspath. I've caught some hints that this isn't subject to the 4096 byte rule? Is that true? So what I want to know is - how can I get my OSD WIM images to use the driver packs? 1. If I use an option 1 slipstream method, and then image that for SMS deployment, will that allow me to use all of the available drivers (assuming I don't delete them)? 2. Can I somehow stop sysprep from adding %SystemDrive% to everything? 3. Can I put a reference elsewhere (winnt.sif?) that will pick-up the drivers instead? I hope I'm missing something obvious, so if someone can set me straight then that'd be super! Thanks! Lights
