 <P>  <h3>Current Installation Procedure</h3>
 In the future, LON-CAPA Installation will be distributed on a CD complete with a  <p>
 customized interface.  Many elements for doing this have been coded, and are in place, but  Scott Harrison
 it awaits completion.  </p>

 </BODY>  <p>
 </HTML>  This is the current list of steps to support LON-CAPA installation.  These
   steps have been tested.</p>
   <ol>
   <li>Get LON-CAPA on a CD by
   <ul>
   <li>Requesting a LON-CAPA installation CD (c/o Helen Keefe, 
   helen@lon-capa.org).</li>
   <li>Or, downloading a LON-CAPA installation
   <a href="http://install.lon-capa.org/3.1/currentcdimage">CD image</A> and
   burning a CD.</li>
   <li>(Depending on whether your computer has a bootable CD-ROM, you may
   need to also make a boot floppy.  Download this floppy disk image file: 
   <a href=
   "http://install.lon-capa.org/3.1/currentcdsource/images/boot-20000407.img">
   boot-20000407.img</a>.  (Download the image file; insert a blank floppy disk;
   and type this command: <tt>dd if=boot-20000407.img of=/dev/fd0</tt>).</li>
   </ul></li>
   <li>Install with CD-ROM
   <ul>
   <li>Follow the <A HREF="instructions_with_cd.html">
   CD-ROM installation instructions</a></li>
   </ul></li>
   <li>After installation, restart the computer.  Login as root.  Enter this
   command (you only need to do this after your first reboot):
   <ol>
   <li><tt>sh /usr/sbin/loncapa_configure</tt></li>
   </ol></li>
   </ol>
