1. Patch SG0000736 Release Note

       This release note describes patch SG0000736 to IRIX 5.3.

       This patch contains a bug fix for all systems that use the
       WD93 SCSI controller (all systems other than Challenge and
       Onyx). It also includes support for the Adtron SDDS PC card
       reader/writer.  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 bug in IRIX 5.3.
       The bug number from Silicon Graphics bug tracking system is
       included for reference.

          o Bug  #261358: This bug could in some circumstances
            cause incorrect information from the SCSI request sense
            command to be returned, due to a cache flushing bug.
            One case where this could occur is in reading tapes in
            variable block mode, when a short read occurs at a
            filemark.  The result was that extra garbage data could
            be read before the filemark status was reported.

          o Add support for PCMCIA devices.  (Bug #292017)

       This patch release includes these subsystems:

          o patchSG0000736.eoe1_sw.unix
       The system must be rebooted before the patch takes effect.

       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.

This information can be used to determine without any doubt whether or not a patch will install on a given system. Just run "versions -n &ltsubsys>" on each of the following subsystems from a command shell on the target system:

SubSystem	Min Value	Max Value
eoe1.sw.unix	1021572036	1029999900

If the version number of the specific subsystem is within the range of the numbers shown above, then the patch will install, otherwise the patch will not install.

NOTE: BE SURE TO CHECK ALL SUBSYSTEMS! Not having base subsystems will also prevent a patch from installing.

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):

41469      2   patchSG0000736
01978    367   patchSG0000736.eoe1_sw
21451      4   patchSG0000736.idb

The following lists the files which get installed from each subsystem in the patch:
