            6. Pull down the "Software" menu and select "Install New". 

            7. When prompted for the host from which to install, choose the 
               local machine and then "Continue". 

            8. In the "Select Media" menu, pull down the "Media Device" menu.  
               Select "Media Images", then choose "Continue". 

            9. When prompted for the "Image Directory", enter "/tmp/p535243c"
               (or the directory where you placed the P535243C patch file
               p535243c_vol.tar in step 2) and choose "OK."

           10. When prompted to select software to install, make sure that 
               the "P535243C" entry is highlighted.  Choose "Install". 
               Once installation is complete, select "OK".

           11. Installation of Escalation Supplement P535243C is now complete.
               To exit the Software Manager, select "Exit" from the "Host"
               menu. 

           12. Once the installation has completed, you can remove or
               archive the P535243C patch file p535243c_vol.tar, the
               media image files, and the containing directory created
               in step 2.

           13. There is no need to reboot the system after installing this
               package.  However, if your system is running any libraries
               or commands that are contained in this package, then these
               programs will continue to run with the old versions of these
               libraries or commands until the system is rebooted.

               Note that when all necessary patches have been installed, it
               is good practice to reboot the system at the earlier
               opportunity.  This will ensure that no programs continue to run
               with the old libraries or commands.
