Patch Installation Instructions:
For Solaris 2.0-2.6 releases, refer to the file and/or
the README within the patch for instructions on using the generic
'installpatch' and 'backoutpatch' scripts provided with each patch.
For Solaris 7-9 releases, refer to the man pages for instructions
on using 'patchadd' and 'patchrm' scripts provided with Solaris.
Any other special or non-generic installation instructions should be
described below as special instructions.  The following example
installs a patch to a standalone machine:
       example# patchadd /var/spool/patch/104945-02
The following example removes a patch from a standalone system:
       example# patchrm 104945-02
For additional examples please see the appropriate man pages.

Special Install Instructions:
When installing on a system that requires this patch, one of two workarounds
must be used to install Solaris:
1) Use a USB keyboard during installation.  This will work for most, but not
all systems, needing this patch.
2) Use a serial console during installation.  The steps for doing this are
shown in detail below.
3) Patch a net installation image and install over the network.
After using either method 1 or 2 to start installing Solaris 8, choose to do
a manual reboot when installation is complete.  This will give you the
chance to install the patch manually before rebooting.
Copy the patch directory onto a floppy as a tar or cpio file previous to
your installation, or use a seperate computer to do this once installation
is done.  You can then extract the contents of the patch to the /tmp
directory from the command line and run patchadd on it.  Note that you need
to apply it using an option you probably have not used previously:
patchadd -R /a 112352-01
The '-R /a' option is needed because your hard disk is mounted as /a during
the installation process and is still mounted there when it is completed.
You can now shutdown the system using 'init 0' and switch to your normal
keyboard.  If you were using method 2, a serial console, you can just use
'init 6' to reboot the system - since no switching of keyboards is required.
                       How to install via a Serial Console
When in the Device Configuration Assistant (DCA) you eventually end up at
the "Boot Solaris" screen.  The title is in the red line at the top of the
At the bottom is a green line showing the function key options you can use.
Use the <F4> key to enter the "Boot Tasks" screen.  On that screen use the
down cursor key to highlight "View/Edit Property Settings" and hit the Space
bar to select it.  You can then hit the <F2> key to execute that function.
You should now see a list of properties that can be set during installation.
These are the same as the eeprom properties you would set in Solaris (man
eeprom).  Use the up and down cursor keys or page-up/page-down to navigate
the list.  Select a property be hitting the Space Bar.  You will then use
the <F3> key to change the property.
Here is a list of the properties we need to change, what they default to,
and what they need to be changed to:
Property Name	Default Value	New Value
output-device	screen		ttya
input-device	keyboard	ttya
You might also need to add a property to this list.  Use <F4> to create a
new property 'ttya-ignore-cd'.  Set it's value to true.  This is only needed
if your cable does not supply CD and DSR correctly.  The symptom of this is
that the install appears to "hang" with no console output.
Be sure to use a Null Modem cable between the COM port of the PC and the
terminal or other system you are using.  Note that these examples are for
the COM1 serial port, known as ttya to Solaris.  For COM2 you would use the
ttyb port, etc.
The baud rate for a serial console defaults to 9600, 8-bits, no parity, and
1 stop bit.  You can change this be creating a property for the port you are
using.  Here is an example for setting COM1 to 38400 baud:
<F4> (create property)
Do a man of the eeprom command (or look at http:/ for the man
page on the eeprom command) to see an explanation of this property.
Anything faster than 38400 risks dropping characters, so it is not
recommended that you go any faster than that for doing an installation.
When you have the properties set up the way you wish, hit the <F2> key to go
back to the "Boot Tasks" screen.  From there you hit <F3> to get back to the
"Boot Solaris" screen.  It will reload the various drivers using during the
boot process to insure your new property values are honored.
At this point you should be using the serial console and have the "Boot
Solaris" screen showing on your serial device screen.  To enter a function
key value, use the Escape key and the number for the function you wish to
use.  For example, to enter the equivalent of <F2>, enter: <Esc><2>
Do not configure the video card for your system during installation.  Exit
out of the kdmconfig program without testing the selection it gives you to
install in the text-only mode using your serial console.  Now proceed as you
would to install any system.
After you have completed the installation, be sure you don't leave the
serial port configured as the console device, unless that is what you want it
to be of course.  To use the normal keyboard you need to set input-device to
be the keyboard and output-device to be the console.  It is recommended that
you use the eeprom command to do this once the system is up and then reboot
the system.
