As said in another post I had the problem of an intruder. I was also getting a readout when booting that said I had a bug in my bios. Well I could not figure it out and finally I cleaned my drive, set it back to zeros, then went in and cleared my bios. I then, had to use windows, and reset my bios to what it was, I then installed fc6. I know longer get the message of a bug in my virus also, I no longer get the message of SIOCGIFFLAGS no such device. I could not believe that was a bug since I have used fedora since its' start
I also had fc6 on Bresnan for several months before moving to qwest. No such problems before. Well I hope this helps someone out there.
