   The following procedure will overwrite your existing /boot/sys/Proc32. Make sure to save it into a backup directory if you wish to keep it.

   ---

   # gzip -d <download-path>/QNX4-Proc32-425Q_20050719.tar.gz
   # tar -xvof <download-path>/QNX4-Proc32-425Q_20050719.tar

   The following files will be installed:

   • /boot/sys/Proc32
   • /boot/sys/Proc32-cksum.txt
6. Make sure that the Proc32 binary is executable:

     # chmod 775 /boot/sys/Proc32
     # chown root:root /boot/sys/Proc32

Please make sure to build the OS image as documented in the QNX 4  manual in order to take advantage of this new Proc32. For instance: # cd /boot # buildqnx -v ./build/myimage ./images/myimage Backup the existing OS image into the alternate boot, in case you ever need it: # cp -V /.boot /.altboot Copy the new OS image into /.boot: # cp -V ./images/myimage /.boot Then reboot your system.
