This section lists the subsystems (and their sizes) of
OCTANE Compression and IMPACT Compression.
If you are installing this product for the first time, the
subsystems marked ``default'' are the ones that are
installed if you use the ``go'' menu item. To install a
different set of subsystems, use the ``install,''
``remove,'' ``keep,'' and ``step'' commands in _i_n_s_t to
customize the list of subsystems to be installed, then
select the ``go'' menu item.
Note: The listed subsystem sizes are approximate. Refer to
the _I_R_I_S _S_o_f_t_w_a_r_e _I_n_s_t_a_l_l_a_t_i_o_n _G_u_i_d_e for information
on finding exact sizes.

2.3 _I_n_s_t_a_l_l_a_t_i_o_n__M_e_t_h_o_d
All of the subsystems for OCTANE Compression and IMPACT
Compression can be installed using IRIX. You do not need to
use the miniroot. Refer to the _I_R_I_S _S_o_f_t_w_a_r_e _I_n_s_t_a_l_l_a_t_i_o_n
_G_u_i_d_e for complete installation instructions.
2.4 _P_r_e_r_e_q_u_i_s_i_t_e_s
OCTANE Compression and IMPACT Compression requires the
following software:
+o OCTANE and IMPACT Digital Media Base Execution
Environment, 6.5 (impactdm)
+o Digital Media Execution Environment, 6.5 (dmedia_eoe)
2.5 _C_o_m_p_a_t_i_b_i_l_i_t_y_:
+o IMPACT Compression requires IMPACT Graphics. It will
not operate with XL, XZ, or other graphics subsystems.
+o IMPACT Compression is compatible with IMPACT Video. It
will not operate with Galileo, Indigo2 Video or other
video subsystem.
2.6 _C_o_n_f_i_g_u_r_a_t_i_o_n__F_i_l_e_s
The video devices have certain configuration values. There
are factory defaults for each device stored in :
/usr/etc/video/videod.defaults._d_e_v_i_c_e,
where _d_e_v_i_c_e is impact for IMPACT Compression as well as
OCTANE Compression. Using _v_i_d_e_o_p_a_n_e_l you can restore these,
as well as saving and restoring a local configuration in
/usr/etc/video/videod.defaults.
