                                 July 26, 1999

       This DigiWARE software package includes device drivers for EPC/X,
       C/X,  Xem  and  Xr  product  families  in  both  EISA and PCI bus
       architectures.

       Description:

            This device driver supports up to four  adapters  in  either
            EISA  or  PCI  bus  slots in HP-UX systems running operating
            system versions 10.10, 10.20, and 11.x.

            This software package  includes  the  device  driver  binary
            images,  Digi  firmware  images,  configuration scripts, and
            support utilities.

            The  package  may  be  installed  with  the  standard  HP-UX
            software installation utility, swinstall.

       Enhancements:

            New in 1.1.0:

                 A binary image supporting HP-UX 11.x has been added  to
                 the  device  driver  package.   This  package is 32-bit
                 ONLY.

       Bug Fixes:

            New in 1.1.0:

                 Added a driver dependency to allow operation on systems
                 in  which the HP-UX Workstation I/O kernel code is not,
                 by default, included in the kernel.

       Known Bugs:

            The bug described below is  installation  related.   If  the
            device  driver installs and your kernel rebuilds and reboots
            successfully, this bug is nnnnooootttt a concern.  As of the  writing
            of  this  document, no bugs have been reported regarding the
            operation of the driver once installed.


       HP-UX 10.10, 10.20, & 11.x    - 1 -                 Release Notes









            At least one instance has been reported of  interoperability
            problems  between  the  Digi  driver  software  and  certain
            platforms with certain revisions of  the  operating  system.
            Digi  is continuing to investigate this and similar reports,
            so we currently do not have a definitive operability matrix.
            The symptom associated with this class of failure:

                 Failures during the ``re-link the kernel''  portion  of
                 configuration  which  indicate that ``the linked output
                 may not run on a PA x.x system''.

            If you are experiencing  behavior  such  as  that  described
            above,    please    contact   a   Digi   technical   support
            representative.

       Design Limitations:

            The  Digi  device  driver  currently  only  supports  32-bit
            versions of the operating system.

            ISA adapters are not supported, including  ISA  adapters  in
            EISA bus slots.

            Only four adapters may be configured per system.

            Xem adapters installed with  this  device  driver  currently
            only  support  the  use  of  PORTS/8em  and  PORTS/16em  EBI
            modules.
