I see what you mean about device mangler, but my AMD athlon has the same issue, shows in device manager with ! but since it won't work to update the driver, reinstall, I end up going into CMOS and having to enable it every time the system is reinstalled. Went from 98, ME to XP on that pc. I see where you are going with this but as I have the same issue, this is the only way to solve this (on mine anyway) and has worked for others. It's really just a pain in the rump but can be solved. If other suggestions work, that's great but as stated, it won't for some older machines as enable enhanced isn't automatically done and has to be enabled. (((IF that option is indeed included))).
