1. Patch SG0001149 Release Note

       This release note describes patch SG0001149 to IRIX 5.3.

       This patch contains bug fixes for XS, XS-24, XZ, Elan, and
       Extreme graphics.  The software cannot be installed on other
       configurations.

       This patch contains bug fixes for IRIX 5.3.  The software
       cannot be installed on other configurations.

       This patch contains fixes for the following bugs in IRIX
       5.3.  Bug numbers from Silicon Graphics bug tracking system
       are included for reference.

          o Once zdraw(TRUE) is called, zdraw(FALSE) doesn't
            properly disable zdraw which makes it impossible to use
            the zbuffer (Bug #257615).

          o Enabling and disabling zdraw corrupts the stencil state
            (Bug #269309).

          o Turning on stenciling breaks the IrisGL zdraw command
            (which allows drawing color data to the zbuffer). (Bug
            #341199)

       This patch release includes these subsystems:

       Because you want to install only the patches for problems
       you have encountered, patch software is not installed by
       default. After reading the descriptions of the bugs fixed in
       this patch (see Section 1.3), determine the patches that
       meet your specific needs.

       If, after reading Sections 1.1 and 1.2 of these release
       notes, you are unsure whether your hardware and software
       meet the requirements for installing a particular patch, run
       inst.


       Patch software is installed like any other Silicon Graphics
       software product.  Follow the instructions in your Software
       Installation Administrator's Guide to bring up the miniroot
       form of the software installation tools.

       Follow these steps to select a patch for installation:

         1.  At the Inst&gtprompt, type

             install patchSGxxxxxxx

             where xxxxxxx is the patch number.

         2.  Select the desired patches for installation.

         3.  Initiate the installation sequence. Type

             Inst> go

         4.  You may find that two patches have been marked as
             incompatible.  If this occurs, you must deselect one
             of the patches.

             Inst> keep patchSGxxxxxxx

             where xxxxxxx is the patch number.

         5.  After completing the installation process, exit the
             inst program by typing

             Inst> quit

       To remove a patch, use the versions remove command as you
       would for any other software subsystem.  The removal process
       reinstates the original version of software unless you have
       specifically removed the patch history from your system.

       versions remove patchSGxxxxxxx

       where xxxxxxx is the patch number.

       To keep a patch but increase your disk space, use the
       versions removehist command to remove the patch history.

       versions removehist patchSGxxxxxxx

       where xxxxxxx is the patch number.

No Requirements Information Available.

These checksums help to provide a 'signature' for the patch inst image which can be used to authenticate other inst images. You can obtain this kind of output by running sum -r on the image (from the command line):

05663      1   patchSG0001149
51858    606   patchSG0001149.eoe1_sw
