Symptoms:
        PHKL_5291:
        During normal O/S execution, Chassis displays are
        interfering with RS232 operations.  This behavior is
        not present in 9.03 or 9.05, and interfers with
        manufacturing's  testing of the Gecko Box. Since Geckos
        are also being  shipped with Chassis  Display output
        enable, this problem  will interfere with any customer device
        attached to this port.

        It is also believed that other PCX-L based workstations
        could be affected by this problem.

Defect Description:
        PHKL_5291:
        As a result of the KRUFT merge, the code that controls
        chassis display allows put chassis for both 700 and 800.

        It can be reproduced by attaching a RS_232 monitor to the
        RS_232 port, and looking for chassis display output during
        a fully booted kernel.

        4. Move to the /tmp directory and unshar the patch:

                cd /tmp
                sh PHKL_5291

        5. Run swinstall to install the patch:

                swinstall -x autoreboot=true -x match_target=true
                        -s /tmp/PHKL_5291.depot

        By default swinstall will archive the original software in
        /var/adm/sw/patch/PHKL_5291.  If you do not wish to retain a
        copy of the original software, you can create an empty file
        named /var/adm/sw/patch/PATCH_NOSAVE.

        Warning: If this file exists when a patch is installed, the
                 patch cannot be deinstalled.  Please be careful
                 when using this feature.

        It is recommended that you move the PHKL_5291.text file to
        /var/adm/sw/patch for future reference.

        To put this patch on a magnetic tape and install from the
        tape drive, use the command:

                swpackage -s /tmp/PHKL_5291.depot -x
                        target_type=tape -d /dev/rmt/0m PHKL_5291
