Software Notes and Recommendations
----------------------------------

SLS ptf7610d should only be installed on:

        UnixWare 7 Release 7.1.1
        Unixware 7 NonStop Clusters Release 7.1.1

This SLS will not install on top the Data Center Feature Supplement (DCAP).
It is not necessary as these problems do not exist in the st01 driver 
included in DCAP.


Installation Instructions
-------------------------

1. Download the ptf7610d.Z file to the /tmp directory on your machine.

2. As root, uncompress the file and add the package to your system
   using these commands:

        $ su
        Password: <type your root password>

        # pkgadd -d /tmp/ptf7610d

that is, without displaying the release notes and asking for
