I am using Vlite to try and slipstream the drivers for my hard drive controllers in to Server 2008. I made one copy with Vlite and when I ran it it did not work (hard drives weren't detected). When I inspected the contents of the disk I couldn't find the driver files any where. I tried making another copy and still had no luck. Any idea what the problem might be, or any other ways to get the drivers on the ISO?
