And yes they were in the drivers folder on the WinPE disc. While looking at the device manager using devmanview there is a section that says ".inf File" and it list oem146.inf So i'm not for sure if that means that is the .inf file it used which I'm assuming it is what it means. If so, there is nothing in the driver package that I have found by this name. All the drivers were labeled as L1....x32 or x64.inf files. So that is interesting.
Windows renames the INF file. It is 146 because it is (probably) the 147th INF file that was injected into the WIM. If you use DISM's /GET-DRIVERS on the mounted image, you can view all the injected drivers, which shows the oem# as well as the original filename and other information. Since you have over 30-40 things in there, you'll probably have to > text file to be able to see them all.
