                     IMPORTANT

Versions of ULTRIX and UWS earlier than
4.3A do not support the R4000 series CPU
upgrade.

Enter this command to see which version of
software is on your system:
>> more /etc/motd

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













See the Guide to Installing ULTRIX for    
information on upgrading your system   
software.

After you successfully boot your software, 
begin the CPU upgrade instructions that
follow.

sion 4.3A or later):

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 command at       
    the console prompt to show the location       
    of your software, for example:  

    >>printenv

    3/rz0/vmunix ­a
    .
    .
    .


In this example the software is located  on a
hard disk that is set to  SCSI ID 0.  Slot 3 is
the location of the disk drive.

You will need this  information to boot your     
software after you complete the upgrade.
