    TITLE: Ascentia 950N, ProStation, Token Ring

    SUMMARY

       The Ascentia 950N may not recognize a Token Ring adaptor.

       This issue affects all Ascentia 950N systems.

    ISSUE

       When a Hypertec HyperRing Blue Classic 16/4 Token Ring adaptor is
       installed in a ProStation, the Ascentia 950N may not recognize the
       adaptor.

    BACKGROUND

       An I/O address conflict exists between the Ascentia 950N and the
       Token Ring adaptor.

    ACTION

       To resolve the issue, implement both of the following changes:

       1. Set the memory address on the Token Ring adaptor to  D0000,
          D4000, D8000 or DC000,

          and

       2. Enter System Setup on the Ascentia 950N (by pressing +)
          and change the I/O address of the Ascentia's built-in audio to
          anything OTHER THAN 220.
