1.5 _I_n_s_t_a_l_l_a_t_i_o_n__i_n_s_t_r_u_c_t_i_o_n_s
This patch is only installable on systems running IRIX 5.3.
This patch requires installation in miniroot mode. To
perform the installation, take the system down and follow
the normal procedures for starting up the installation tool
from the supplied release media. It is recommended that you
select all the patch subsystems that correspond to software
already installed on the system.
One way in which software patches differ from full releases
and maintenance releases is that patches are reversible:
you can remove the patch and restore the installed software
to its state before the patch was applied. This is done by
using the _v_e_r_s_i_o_n_s command as superuser:

Since this patch replaces some kernel object files, it is
necessary to rebuild the kernel image and reboot after
removing the patch:
