Been using nLite with windows XP for a little bit and really enjoying it so far. I am having a little problem with one installation I have made. I seem to be missing the BDA or Broadcast Driver Architecture subsystem.. I have searched the forum and can't find anything indicating what installs that? I have two questions. 1) What installs BDA? 2) Is there anyway to install BDA after installing XP without it?
