upgrade.

Enter this command to see which version of
software is on your system:

If you do not have ULTRIX and UWS Ver­
sion 4.3A or later, you must upgrade your
software before you continue.











See the Guide to  Installing ULTRIX for in­
formation on upgrading your system     soft­

1.  Enter this command at the superuser        
     prompt (#) to shut down the software:

   # /etc/shutdown ­h now

2.  If you have just installed a new version   
     of software, enter the printenv com­       
     mand at the console prompt to show the                  
     location of your software.  For example:
