  31 /*  FUNCTION
  32         This is the old function for adding devices to the system. It
  33         is recommended that you use the AddBootNode() function.
  34
  35         Unlike AddBootNode() you will have to add a BootNode to the
  36         system yourself.
  37
  38     INPUTS
  39         bootPri     -   The priority of the device (-128 --> 127).
  40         flags       -   Flags (ADNF_STARTPROC etc)
  41         deviceNode  -   The device to add to the system.
  42
  43     RESULT
  44         non-zero if everything succeeded, zero on failure.
  45
  46     NOTES
  47         It is much better to use AddBootNode() as it will also
  48         construct the BootNode structure, and add it to the system.
  49
  50     EXAMPLE
  51         //  Add a bootable disk to the system. This will start a
  52         //  file handler process immediately.
  53
  54         if( AddDosNode( 0, ADNF_STARTPROC, MakeDosNode( paramPacket )))
  55         {
  56             // AddDosNode() ok
  57         }
