       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
       _i_n_s_t.  The _i_n_s_t program does not allow you to install
       patches that are incompatible with your hardware or
       software.

       Patch software is installed like any other Silicon Graphics
       software product.  Follow the instructions in your _S_o_f_t_w_a_r_e
       _I_n_s_t_a_l_l_a_t_i_o_n _A_d_m_i_n_i_s_t_r_a_t_o_r'_s _G_u_i_d_e to bring up the miniroot
       form of the software installation tools.

       Follow these steps to select a patch for installation:

         1.  At the Inst> prompt, type

             iiiinnnnssssttttaaaallllllll ppppaaaattttcccchhhhSSSSGGGG_x_x_x_x_x_x_x

             where _x_x_x_x_x_x_x is the patch number.

         2.  Initiate the installation sequence. Type

             IIIInnnnsssstttt>>>> ggggoooo

         3.  You may find that two patches have been marked as
             incompatible.  (The installation tools reject an
             installation request if an incompatibility is
             detected.)  If this occurs, you must deselect one of
             the patches.

             where _x_x_x_x_x_x_x is the patch number.

         4.  After completing the installation process, exit the
             _i_n_s_t program by typing

             IIIInnnnsssstttt>>>> qqqquuuuiiiitttt

       To remove a patch, use the _v_e_r_s_i_o_n_s _r_e_m_o_v_e 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.

       where _x_x_x_x_x_x_x is the patch number.

       To keep a patch but increase your disk space, use the
       _v_e_r_s_i_o_n_s _r_e_m_o_v_e_h_i_s_t command to remove the patch history.
