       This release note describes patch SG0001795 to IRIX 6.3 for
       O2 including R10000.

       1.1  _S_u_p_p_o_r_t_e_d__H_a_r_d_w_a_r_e__P_l_a_t_f_o_r_m_s

       This patch contains bug fixes and performance optimizations
       for all O2 systems.  The software cannot be installed on
       other configurations.

       This patch contains bug fixes and performance optimizations
       to the OpenGL run-time libraries on a system running IRIX
       6.3 for O2 including R10000 (version 12161207).  The
       software cannot be installed on other configurations.

       This patch contains fixes for the following bugs in IRIX 6.3
       for O2 including R10000.  Bug numbers from Silicon Graphics
       bug tracking system are included for reference.
