According to DEC, you will need PSI V4.0 before you can install VMS V4.4.
The last I heard from DEC was that PSI V4 was in SDC and should be out the
first part of August.  

PSI V4 has some enhancements beyond support under VMS V4.4, including:
(From the "VAX PSI Information Sheet" the PSI group was handing out at DECUS)

  o Ability to connect one VAX PSI node to more than one type of
    network simultaneously.  (e.g. TELENET and TYMENET and private net)
  o DCE support.  Allows you to run X.25 back-to-back, without a
    "network".  Conforms to ISO 8208
  o CCITT 1984 support except for "multi-link recommendations" and
    "extended packet sizes and level-2 windows" on KMS/KMV devices.
  o Both PSI and PSI ACCESS can reside on a node, thereby granting access from
    the PSI node to networks connected to another PSI ACCESS node.
  o Interactive tracing and other debugging aids.
  o Some new networks: DATAPAK, DATEX-P, INFONET, TELEPAC.
  o New processor support: 8200, etc...
    BI-bus machines only supported with the DMB32 combo device.
    VAXstation I support dropped.
