Tru64 UNIX Version 5.1B-4

This kit provides patches to upgrade your Version 5.1B Tru64 UNIX 
operating system to Version 5.1B-4.

This release is a minor update to Version 5.1B and does not require 
the update installation procedure of the operating system.  As a 
result, this release preserves total binary compatibility with 
previous releases of Tru64 UNIX and does not require ISV application 
recertification or recompilation.

Before installing the patches for your operating system, familiarize 
yourself with the following documentation:

o Patch Kit Installation Instructions

  You can access this guide in PDF, HTML, and TXT formats from the 
  top-level directory of this kit.

o Patch Summary and Release Notes

  You can access this manual in PDF, HTML, and TXT formats from the
  ./TRU64_UNIX_5.1B directory.

We recommend that you print these documents before beginning the 
installation.

In addition to these documents, HP also recommends that you review
the information in the "Technical Updates for the Version 5.1B and 
Higher Operating System and Patches" document, which is available 
on the Tru64 UNIX online documentation web site:
