Yes, this is normal. In the BTS Drivers Packs there are a lot of .inf files which contains links to other windows drivers (like w2k, 98 and me). These drivers are already ripped out to save space. I tried several detections for this but I didn't get it working. However I could make a option to skip .com, .sys, .dos and .vxd files. I believe these files have nothing to do with windows xp (I think).
