  Log:
  When rebooting the machine jump to 0xf000:0xfff0 instead of 0xffff:0x0.
  
  While we end up the same place, we end up with two different CS register
  values after the jump and 0xf000 is compatible with the hardware reset
  value.
  
  This makes a difference if the BIOS does a near jump before a far jump.
