    TITLE: Ungermann Bass NIUpc/EOTP Cards, Pentiums

    SUMMARY

       The Ungermann Bass NIUpc/EOTP Ethernet card will not function
       properly in faster Pentium systems (generally 133Mhz and above).

       This issue affects the following systems: 501895, 501860, 501956,
       501972, and 501981.

    ISSUE

       The Ungermann Bass NIUpc/EOTP card may not support faster systems,
       and Ungermann Bass has no plans to provide support for faster
       Pentium systems.  The system reports the failure symptom as:

          "NIU Diagnostic error #FF".

    BACKGROUND

       Ungermann Bass stopped making network cards several years ago, and
       they no longer provide any support for this card.  Ungermann Bass
       has confirmed that the same problem exists in faster systems from
       several manufacturers, and they have no work-around or resolution
       for it.

    ACTION

       Replace the Ungermann Bass NIUpc/EOTP with an Ethernet card that
       supports faster Pentium systems.

       Pentium is a registered trademark of Intel Corporation.
