      [Expert@HostName]# touch $FWDIR/boot/modules/fwkern.conf

    2. Edit the $FWDIR/boot/modules/fwkern.conf file in Vi editor:

      [Expert@HostName]# vi $FWDIR/boot/modules/fwkern.conf

    3. Add the following line (spaces are not allowed):


    4. Save the changes in the file and exit from Vi editor.
