  *      If you have strange problems with nVidia chipset systems please
  *      see the SI support documentation and update your system BIOS
  *      if neccessary

+ *  The Dell DRAC4 has some interesting features including effectively hot
+ *  unplugging/replugging the virtual CD interface when the DRAC is reset.
