Ok, thanks for that clarification Regarding the UIU, i'm not sure wether they have edited the inf files or not. Almost all of their (i don't really mean theirs) drivers are put in the root folder at this location: C:\Windows\inf\UIU Then there are about 50 subfolders with only a few drivers in them each. The folders are named A0100,A0101 etc trickling down to B_25699. The reason I think they have edited the inf files is cause some of them, located in the root, points to some of these subfolders, ex: [sourceDisksNames.x86] 1 = %DiskId%,,,.\B_14575 [sourceDisksNames.ia64] 1 = %DiskID%,,,.\B_14575 PS. If I would to exceed the byte limit by doing some drastic "foldering", maybe regedit would let me know ? Thanks for answering
