    Since you are using an RPM-based distribution, you have the option to 
    build an RPM from the blcr sources, as described in the "Building a 
    binary RPM from source RPMS" section of the BLCR Admin guide (in the 
    doc/html directory of the BLCR sources, or online at  If you do 
    this and install the resulting .rpm files (something like "rpm -ihv 
    /usr/src/redhat/RPMS/i686/blcr*.rpm" as root) then everything I describe 
    below should be taken care of automatically.
    For completeness, I describe below how to handle the module loading and 
    environment settings if one does not use the RPM approach.

    The loading of kernel modules at boot time is distribution dependent and 
    therefore BLCR doesn't offer one perfect solution for every situation.  
    However, Red Hat 9 is one we know how to handle.  There is a sample 
    blcr.rc script in the etc directory of the BLCR source distribution.  
    You can use this example by running two commands as root:
    1) From to top f you BLCR build directory, run "make -C etc install" to 
    configure the example and copy it into place.
    2) Then run "/sbin/chkconfig --add" to set the links needed to run it at 
    boot time.

    As described in the BLCR Admin guide you can add commands to 
    /etc/profile and /etc/cshrc:
    For Bourne-style shells, add the following 4 lines to /etc/profile:
    For csh-style shells, add the following 3 lines to /etc/cshrc
        setenv PATH ${PATH}:PREFIX/bin
        setenv MANPATH ${MANPATH}:PREFIX/man
    In both cases, you need to replace "PREFIX" with "/usr/local" or 
    whatever prefix you specified at configure time.

    Let me know if you still have questions.
