When installing a PGX Frame Buffer (PN 370-2256) in an Ultra 5 or Ultra 10
you will need to follow these steps to have it to work properly.

1. Turn the power off and install the PGX Frame Buffer into a PCI slot on
   the PCI riser card.
   
   **** Remember to use proper static protection when installing ****
   **** boards or devices in the system.                         ****

2. Turn the power back on. Once the video comes back hold down the stop key
   and the letter A key and the same time. This will stop the system from
   booting and allow you to issue the commands needed for the PGX Frame
   Buffer to work properly. At the OK prompt issue the show-devs command. 
   This shows the devices in the system and their respective paths. You
   will need to look for a line that looks like the example below.

   Example:

     OK show-devs


     /pci@1f,0/pci@1/SUNW,m64B@1
                               /\ 
                               ||
                      PCI SLOT (1,2,3,4)

   The last number will depend on what slot you installed the PGX
   Frame Buffer into on the PCI riser card.

3. You will now need to create an nvalias for the PGX Frame Buffer
   using the nvalias command. Example shown below.

   Example:

     OK nvalias screen1 /pci@1f,0/pci@1/SUNW,m64B@1
                ------- ---------------------------  
                  /\               /\ 
                  ||               ||
                  ||     (path from show-dev command)
                  ||
      (screen1 is used for example only)
      
      The name of the nvalias can be any name you want is to be.
      
      *****Caution, be careful not to duplicate a name already used.******
      
      You can see what has been used by using the devalias command at the
      OK prompt. This will display the aliases already in use.

      After creating the nvalias. Issue the devalias command at the OK prompt
      to verify that the nvalias you just created is present and has the
      correct path.

4.  Now that the nvalias has been created, you will now need to set the
    output-device to look at the new nvalias instead of the default setting.
    The default nvalias is screen, which points to the onboard video.
    You do this by using the setenv command. Example shown below.

    Example:

      OK setenv output-device screen1
     
    The system will echo what you set the environment variable to.

      output-device =       screen1

5.  You are now all set to issue the reset command at the OK prompt.
    
    OK reset
    
    While the system is rebooting, change the monitor from the onboard video
    to the PGX Frame Buffer. When the system initializes the video, it will
    initialize the PGX Frame Buffer and not the onboard video. If the OS is
    already installed, will need to do a stop A after the video initializes
    and issue the boot -r command to add the drivers for the PGX Frame Buffer. 
    This is not an issue if you are doing a new install of the OS on the
    system. During installation, it will install the drivers necessary for
    the devices in the system.

*****IMPORTANT NOTE*****

If a Stop N or L1 N is done after the above commands have been issued, you
will have to perform the steps listed above once again to have the system
use the PGX Frame Buffer instead of the onboard video. A stop N or L1 N,
will set the nvram back to it's default settings, and should only be used
when it is absolutely necessary.
