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/sbin/prtconf -V
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 "prtconf -V" output. Find
the revision number and compare with the revision on the entries below
that of the "flash-update-Ultra510-latest" line;
Available Firmware Revisions
----------------------------

POST: 3.1.0

POST: 3.1.0
LATEST flash-update-Ultra510-18; flash-update-Ultra510-latest
All Models
OBP: 3.31 Version 0 created 2001/07/25 20:36
POST: 3.1.0
3) Is the UPGRADE NECESSARY?
If the current Flash PROM revision matches the version numbers
given under
the flash-update-Ultra510-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 latest "flash-update" file 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.
** CAUTION ** 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 unsure how to do this then
consult your system "Installation Guide" or "Service Manual".)
e) Set JP2 to write enable at 2+3. Default is write protect at 1+2
Locate jumper JP2.
Jumper JP2 provides a write enable/disable mechanism for the
Flash PROM. JP2 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 JP2 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 JP2 then consult Figure 1-3 in the
"Sun Flash PROM Guide for Workstations and Workgroup Servers -
Standalone Version").
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.
** 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-Ultra510-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.
