       INTRODUCTION:

            This DigiWARE 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:

            The driver package now supports 64-bit platforms.

       BUG FIXES:

            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.

            DPA loopback testing functionality has now been fixed.

            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.

       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:

                 PHKL_16209

            Neither ISA nor EISA adapters are now supported.

            Only four adapters may be configured per system.

       HISTORY:

            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.
