*  PLEASE REVIEW NOT ONLY THIS README BUT ALSO ADDITIONAL DOCUMENTATION GIVEN.
   The file "802-3233-15.ps" is a PostScript copy of the "Ultra 1 and
   Ultra 2 System Flash PROM Programming Guide" which  provides 

   (i) a board-level diagram that gives the approximate location of the 
       hardware jumpers (that will need to be changed), and
       
   (ii) it also contains emergency instructions in the unlikely event that
        the Flash update should fail.
       
   Note, however, that The Programming Guide was originally written for 
   a user who is running the Flash PROM update utility from a bootable
   CDROM, and thus it will not contain the proper boot commands for
   installation of this patch.  Also note that the instructions in
   the document for installing packages are not valid for this patch.

Patch Installation instructions (in detail):
============================================

The required steps are explained in greater detail below.

1)  Determine the System's Current Firmware Revisions
    -------------------------------------------------

    While the OS is running the following command may be used to
    determine the current system firmware revisions;

	/usr/platform/sun4u/sbin/prtdiag -v | grep OBP

    The firmware revisions may also be determined from the PROM monitor's
    "ok" prompt with the following command;

	.version

2)  Compare the current Flash Prom firmware revision with the available or 
    latest Flash Prom firmware revisions.
    
    Compare the output of the OBP line in the "prtdiag -v" output. Find the
    revision number and compare with the revision on the entries below that
    of the "flash-update-Ultra1-latest" line

3)  Is the UPGRADE NECESSARY?

    If the current Flash Prom revision matches the version numbers given under
    the flash-update-Ultra1-latest line, then STOP Here. This UPGRADE IS NOT
    NECESSARY.
   
    If the current Flash Prom firmware revision is lower than the latest
    firmware revision in this patch, then proceed to the next step.
   
4) Preparing the System
   ---------------------

  a) As root, copy the "flash-update-Ultra1-latest" file from the
     directory containing the patch to the root directory.  (Do not
     boot/run revisions lower than the latest unless you are absolutely
     sure that that is what you want to do!  Should you need to install
     an older revision than what is supplied in the "-latest" binary
     then copy the appropriate SUNW,501-2836-0x or SUNW,501-3082-0x file
     in lieu of "flash-update-Ultra1-latest" file.)
  
     # cp flash-update*  /
     # chmod 755 /flash-update*
     
     In order to boot the binary, it must be located within the root
     partition.  If it is not already located within the root partition
     then move it to /.  If the binary is already located elsewhere 
     within the root partition then note the exact filepath so that the
     binary can be booted later.

  b) As root, exit the OS such that the system returns to the PROM's "ok"
     prompt: 

     # halt

       ok
       
  c) Power off the system.

** WARNING **  Do not attempt to access any part of the system hardware
               with the system power still on!

  d) Remove the system top cover.  (If you're unsure how to do this then
     consult your system "Installation Guide" or "Service Manual".)

  e) Set J2003 to write enable at 2+3. Default is write protect at 1+2
  
     Locate jumper J2003.  NOTE that a plug-in card may be installed in
     the system which covers J2003 - if this is the case then you will
     have to remove the plug-in card in order to access J2003.

     Jumper J2003 provides a write enable/disable mechanism for the
     Flash PROM.  J2003 normally connects pins 1+2, which causes the
     Flash PROM to be write protected.  To enable pacth installation,
     write enable the Flash PROM by MOVING the J2003 jumper from pins 1+2 
     to pins 2+3.  If you have difficulty locating J2003 then consult
     Figure 1-1 in the "Ultra 1 and Ultra 2 System Flash PROM Programming
     Guide".
     
     **IMPORTANT NOTE**: If this jumper is NOT set to WRITE ENABLE, the 
     Flash update will fail.
     
     If a plug-in card was removed to access J2003 in the step above
     then reinstall the card now.

  f) Replace the system top cover.


5)  Running the Flash Update Utility
    --------------------------------

  a) Power on the system
 
     Wait for the PROM's banner to appear, and then
     
  b) use the Stop-A keys (or Break key, if running from a serial line) to
     abort the auto-boot sequence.

     ** IMPORTANT NOTE **  As a consequence of the upgrade, the system's
     Non-Volatile RAM (NVRAM) configuration variables MAY BE reset to
     their default values (except that the "diag-switch?" may be set to
     "true").  If you have any custom NVRAM CONFIGURATION SETTINGS, then
     you SHOULD NOTE THEM DOWN AT THIS TIME.  You should also note down
     the "diag-switch?" setting.  To do this, at the PROM's "ok" prompt
     type "printenv diag-switch?".

  c) The system should now display the PROM monitor's "ok" prompt.
     Now boot the Flash update utility as given below:

     ok boot disk /flash-update-Ultra1-latest

     NOTE: If your system's boot device is not "disk" then you will
           have to specify the appropriate devalias (e.g. disk2).
           If the binary is located in a location other than / then
           provide the entire filepath after the boot device.

     Answer the questions as prompted by the utility.

  ** IMPORTANT NOTE **  Because the NVRAM configuration variables may be
  modified during the reset process, the system may behave differently
  than it did before the firmware was upgraded.  The system may attempt
  to boot from a different device, and it is possible, depending on
  the individual system configuration, that the console input/output
  device assignment may have been modified such that output may no
  longer appear on a previously assigned output device.

  Once the PROM's banner reappears then use the Stop-A keys (or Break
  key, if running from a serial line) to abort the auto-boot sequence.
  If you noted any custom NVRAM settings earlier then this is the time
  to restore them.  You may also wish to check the "diag-switch?"
  configuration variable to see if it has been changed to "true".  To
  do this, at the PROM's "ok" prompt type "printenv diag-switch?".  If
  "diag-switch" was changed to "true" because of the firmware upgrade
  then set it back to "false" by typing "setenv diag-switch? false".

6)  Verifying successful Flash Prom Update

    Verify from the results of the .version command that the OBP
    version matches the OBP version given above under the
    flash-update-Ultra1-latest entry in Step 2.
   
7)  Restoring the system

    The system should be restored to the original set-up as follows:

    a) Turn the power to the system off.
    b) Remove the top cover and move jumper J2003 to pins 1+2.
    c) Replace the top cover.

    If any problems should be encountered during the firmware upgrade
    then consult the "Ultra 1 and Ultra 2 System Flash PROM Programming
    Guide".  

8)  Resume operations

    a) Turn on the system power and allow the system to boot the
       operating system.
       
    b) Once the system has rebooted you may wish to remove the Flash Update
       binaries and documents since they will no longer be needed.
       
       # rm /flash-update*

    c) Remember to remove the files from their original location if
       they were not extracted directly into the root directory.
