I've got to agree with diolma 'cos since getting an external router all those pesky idiots trying to access my bios have also disappeared. The one I've got only cost about 50 which is about $30-35, or there abouts, and really isn't too much to spend to give you confidence that you won't get corrupted. You should also be able to plug your 24/7 connection into the router and still be able to unplug the conection to your machine. Whenever I come offline I always pull the plug which is just a case of having been corrupted myself too many times. Catlin
