       INTRODUCTION:

            This Digi software package includes device drivers  for  PCI
            adapters in the EPC/X, C/X, Xem and Xr product families.  It
            supports up to four adapters,  and  includes  all  necessary
            driver  binaries,  firmware  images,  configuration scripts,
            etc.  It may be installed with the standard  HP-UX  software
            installation utility ``swinstall''.

       SUPPORTED PRODUCTS:

            PCI Xr, PCI Xr/920, PCI Xem, PCI EPC/X, PCI C/X

       ENHANCEMENTS:

            Added support for HP-UX 11.11.

       BUG FIXES:

            Fixed a driver panic on smp machines.

            Fixed a driver panic that occurred when em ports are defined
            but no ports are detected at boot time.

            Fixed a driver bug that caused writes on non-blocking  ports
            to fail.

       KNOWN LIMITATIONS:

            The following patches may be required if you have  a  multi-
            processing environment.  Contact HP technical support if you
            need help determining whether these patches are necessary on
            your machine:

                 PHNE_20008

                 PHKL_16209

            Neither ISA nor EISA adapters are now supported.


       HP-UX 11.00 and 11.11  - 1 -                 Release Notes









            Only four adapters may be configured per system.

       HISTORY:

            1.2.0:

                 Added support for 64-bit platforms

                 The package, on some platforms, would build an  invalid
                 kernel  image  which  would  result  in an inability to
                 boot.   The  inconsistent  build  procedure  has   been
                 corrected

                 Fixed DPA loopback testing functionality

                 The driver would sometimes unexpectedly shift into  HP-
                 UX's   ``block   I/O   mode'',  resulting  in  spurious
                 character  transmission  upon  data  reception.    This
                 behavior is now corrected.

            1.1.0:

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

                 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.
