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/sbin/prtconf -V
      or
/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" or "prtconf -V"
output. Find the revision number and compare with the revision on the
entries below that of the "flash-update-Ultra1-Modelxxx-latest" line

   Available Firmware Revisions
   ----------------------------

-09/140 Model 140: flash-update-Ultra1-Model140-latest
      Sun Ultra 1 SBus 3.35 Version 0 created 2004/04/19 12:15
      Sun Ultra Enterprise 1 SBus POST 3.10.6 10/18/1996 10:19 AM

-09/170 Model 170: flash-update-Ultra1-Model170-latest
      Sun Ultra 1 SBus 3.35 Version 0 created 2004/04/19 12:16
      Sun Ultra Enterprise 1 SBus POST 3.10.6 10/18/1996 10:19 AM

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" files from the directory containing the
   patch to the root directory as follows:

   # cp flash*latest  /
   # 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.
   Check that you have security-mode = none in the PROM setup.
   This is necessary because it is possible the upgrade process
   will corrupt the PROM password.

   ok printenv

   If you do, set the security mode to none

   ok setenv security-mode none

  d) Power off the system.

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

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

  f) 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 patch installation,
   write enable the Flash PROM by MOVING the J2003 jumper from pins 1+2
   to pins 2+3.

   **IMPORTANT NOTE**: If this jumper is NOT set to WRITE ENABLE, the
   Flash update will fail.

   (If you have difficulty locating J2003 then consult Figure 1-1 in the
   "Sun Flash PROM Guide for Workstations and Workgroup Servers -
   Standalone Version"

.

   If a plug-in card was removed to access J2003 in the step above
   then reinstall the card now.

  g) 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.

   ** NOTE **  If the flash update completes normally then the values
   contained within the system's Non-Volatile RAM (NVRAM) configuration
   variables will be retained.  However, if the update process is some-
   how interrrupted then it is possible that any non-default values
   contained in NVRAM will be lost.  For this reason it is recommended
   that you note down on paper the contents of any NVRAM configuration
   variable which has been customized so that they may be manually
   restored at a later time, if necessary.  (Use the PROM's "printenv"
   command to list the variables and their values.)

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

   CAUTION: Do not boot/run revisions lower than the latest unless you
      are absolutely sure that that is what you want to do!

   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.

  Note that the section "Restoring previous NVRAM environment settings..."
  up to the "Resetting ..." line will only be displayed on serial port A.
  If you are running from the keyboard/console devices then you will not
  see those lines displayed.

  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 the system begins to boot.

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 "Sun Flash PROM Guide for Workstations and Workgroup
Servers - Standalone Version".

  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.

9)  Restoring PROM security mode settings

If you wish to turn on security-mode=command or security-mode=full
in the PROM, ensure you set the password first. For example:

   ok  setenv password

   ok  setenv security-mode command

Failing to set the password before the security-mode can leave you
locked out of the system.

**WARNING:****WARNING:****WARNING:****WARNING:****WARNING:****WARNING:**

*  PLEASE READ THE INSTRUCTIONS CAREFULLY AND ENTIRELY.  PLEASE FOLLOW THE
INSTRUCTIONS EXACTLY AS THEY ARE STATED.

*  FAILURE TO FOLLOW INSTRUCTIONS COULD EITHER RESULT IN A DEFECTIVE BOARD OR
UNSUCCESSFUL FLASH PROM UPDATE.

*  THIS IS NOT A STANDARD PATCH in that it does not use the installpatch
and backoutpatch scripts.

*  THIS PATCH CANNOT BE INSTALLED ON AN ONLINE OPERATING SYSTEM BECAUSE
THE INSTALL INSTRUCTIONS REQUIRES THAT THE SYSTEM BE BROUGHT DOWN.
BE SURE TO SCHEDULE DOWN TIME TO INSTALL THIS PATCH.

*  INSTALLATION OF THIS PATCH REQUIRES A HARDWARE JUMPER CHANGE. IF YOU ARE
UNSURE ON HOW TO OPEN THE SYSTEM BOX, PLEASE ENSURE THAT A QUALIFIED
PERSON, WITH THE STATIC WRIST STRAP KIT NEEDED TO SERVICE ELECTRONIC
EQUIPMENT, IS AVAILABLE TO COMPLETE THIS ACTIVITY. FAILURE TO USE STATIC
PROTECTION KIT OR IMPROPER HANDLING COULD RESULT IN THE DAMAGE OF THE
SYSTEM BOARD.

*  PLEASE REVIEW NOT ONLY THIS README BUT ALSO ADDITIONAL DOCUMENTATION
GIVEN.
The file "802-3233-xx.ps" (where xx stands for the latest numeric
revision) is a PostScript copy of the "Sun Flash PROM Guide for Workstations
and Workgroup Servers - Standalone Version", which  provides the following;

(i) A board-level diagram that gives the approximate location of the
   hardware jumpers (that will need to be changed).

(ii) Emergency instructions in the unlikely event that the Flash
      update should fail.

Note, however, that The Flash PROM 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.
