    1.5 Installation Instructions
           Because you want to install only the patches for problems
           you have encountered, patch software is not installed by
           default.  After reading the descriptions of the bugs fixed
           in this patch (see Section 1.3), determine the patches that
           meet your specific needs.
    
           If, after reading Sections 1.1 and 1.2 of these release
           notes, you are unsure whether your hardware and software
           meet the requirements for installing a particular patch, run
           inst.  The inst program does not allow you to install
           patches that are incompatible with your hardware or
           software.
    
           Patch software is installed like any other Silicon Graphics
           software product.  Follow the instructions in your Software
           Installation Administrator's Guide to bring up the miniroot
           form of the software installation tools.
    
           Follow these steps to select a patch for installation:
    
    
             1.  At the Inst> prompt, type
    
                 install patchSGxxxxxxx
    
                 where xxxxxxx is the patch number.
    
             2.  Initiate the installation sequence. Type
    
                 Inst> go
    
             3.  You may find that two patches have been marked as
                 incompatible.  (The installation tools reject an
                 installation request if an incompatibility is
                 detected.)  If this occurs, you must deselect one of
                 the patches.
    
                 Inst> keep patchSGxxxxxxx
    
                 where xxxxxxx is the patch number.
    
             4.  After completing the installation process, exit the
                 inst program by typing
    
                 Inst> quit
    
    
    1.6 Patch Removal Instructions
           To remove a patch, use the versions remove command as you
           would for any other software subsystem.  The removal process
           reinstates the original version of software unless you have
           specifically removed the patch history from your system.
    
           versions remove patchSGxxxxxxx
    
           where xxxxxxx is the patch number.
    
           To keep a patch but increase your disk space, use the
           versions removehist command to remove the patch history.
    
           versions removehist patchSGxxxxxxx
    
           where xxxxxxx is the patch number.
    
    
    1.7 Known Problems
    
    1.7.1 Bug 284409 The fixes for bug 284409 require that
           patch #2400 (or later) also be installed. patch #2400 and
           patch #2054 (or later) may be installed in either order. If
           patch #2400 is not installed, then the complete fixes for
    
    
           bug# 284409 will not be present and there is the possibility
           that the kernel may panic when svr4net is enabled (rpcbind)
           and used under load.

    INST SUBSYSTEM CHECKSUMS

    These checksums help to provide a 'signature' for the patch inst image which can be used to authenticate other inst images. You can obtain this kind of output by running sum -r on the image (from the command line):
