 758 <h2 id="_description">DESCRIPTION</h2>
 759 <div class="sectionbody">
 760 <div class="paragraph"><p>ISOLINUX is a boot loader for Linux/i386 that operates off ISO 9660/El
 761 Torito CD-ROMs in "no emulation" mode.  This avoids the need to create
 762 an "emulation disk image" with limited space (for "floppy emulation")
 763 or compatibility problems (for "hard disk emulation".)</p></div>
 764 <div class="paragraph"><p>To create an image, create a directory called "isolinux/" (or, if you
 765 prefer, "boot/isolinux/") underneath the root directory of your ISO image
 766 master file tree.  Copy isolinux.bin, a config file called
 767 "isolinux.cfg" (see <strong>syslinux.cfg</strong>(5) for details on the configuration file),
 768 and all necessary files (kernels, initrd, display files, etc.) into this
 769 directory, then use the above command to create your ISO image (add
 770 additional options as appropriate, such as -J or -R).  If you named the
 771 directory boot/isolinux that should of course be<br />
 772         -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat.</p></div>
 773 </div>
 774 </div>
 775 <div class="sect1">
 776 <h2 id="_config_file_directory">CONFIG FILE DIRECTORY</h2>
 777 <div class="sectionbody">
 778 <div class="paragraph"><p>ISOLINUX will search for the config file directory in the order
 779 /boot/isolinux, /isolinux, /.  The first directory that exists is
 780 used, even if it contains no files.  Therefore, please make sure that
 781 these directories don&#8217;t exist if you don&#8217;t want ISOLINUX to use them.</p></div>
 782 </div>
 783 </div>
 784 <div class="sect1">
 785 <h2 id="_hybrid_cd_rom_hard_disk_mode">HYBRID CD-ROM/HARD DISK MODE</h2>
 786 <div class="sectionbody">
 787 <div class="paragraph"><p>Starting in version 3.72, ISOLINUX supports a "hybrid mode" which can
 788 be booted from either CD-ROM or from a device which BIOS considers a
 789 hard disk or ZIP disk, e.g. a USB key or similar.</p></div>
 790 <div class="paragraph"><p>To enable this mode, the .iso image should be postprocessed with the
 791 "isohybrid" script from the utils directory:</p></div>
 792 <div class="literalblock">
 793 <div class="content">
 794 <pre><code>isohybrid filename.iso</code></pre>
 795 </div></div>
 796 <div class="paragraph"><p>This script creates the necessary additional information to be able to
 797 boot in hybrid mode.  It also pads out the image to an even multiple
 798 of 1 MB.</p></div>
 799 <div class="paragraph"><p>This image can then be copied using any raw disk writing tool (on Unix
 800 systems, typically "dd" or "cat") to a USB disk, or written to a
 801 CD-ROM using standard CD burning tools.</p></div>
 802 <div class="paragraph"><p>The ISO 9660 filesystem is encapsulated in a partition (which starts
 803 at offset zero, which may confuse some systems.)  This makes it
 804 possible for the operating system, once booted, to use the remainder
 805 of the device for persistent storage by creating a second partition.</p></div>
 806 </div>
 807 </div>
 808 <div class="sect1">
 809 <h2 id="_miscellaneous">MISCELLANEOUS</h2>
 810 <div class="sectionbody">
 811 <div class="paragraph"><p>Make sure you have a recent enough version of mkisofs.  I recommend
 812 mkisofs 1.13 (distributed with cdrecord 1.9), but 1.12 might work as
 813 well (not tested.)</p></div>
 814 <div class="paragraph"><p>ISOLINUX resolves pathnames the following way:</p></div>
 815 <div class="ulist"><ul>
 816 <li>
 817 <p>
 818 A pathname consists of names separated by slashes, Unix-style.
 819 </p>
 820 </li>
 821 <li>
 822 <p>
 823 A leading / means it searches from the root directory; otherwise the
 824   search is from the isolinux directory (think of this as the "current
 825   directory".)
 826 </p>
 827 </li>
 828 <li>
 829 <p>
 830 . and .. in pathname searches are not supported.
 831 </p>
 832 </li>
 833 <li>
 834 <p>
 835 The maximum length of any pathname is 255 characters.
 836 </p>
 837 </li>
 838 </ul></div>
 839 <div class="paragraph"><p>Note that ISOLINUX only uses the "plain" ISO 9660 filenames, i.e. it
 840 does not support Rock Ridge or Joliet filenames.  It can still be used
 841 on a disk which uses Rock Ridge and/or Joliet extensions, of course.
 842 Under Linux, you can verify the plain filenames by mounting with the
 843 "-o norock,nojoliet" option to the mount command.  Note, however, that
 844 ISOLINUX does support "long" (level 2) ISO 9660 plain filenames, so if
 845 compatibility with short-names-only operating systems like MS-DOS is
 846 not an issue, you can use the "-l" or "-iso-level 2" option to mkisofs
 847 to generate long (up to 31 characters) plain filenames.</p></div>
 848 <div class="paragraph"><p>ISOLINUX does not support discontiguous files, interleaved mode, or
 849 logical block and sector sizes other than 2048.  This should normally
 850 not be a problem.</p></div>
 851 <div class="paragraph"><p>ISOLINUX is by default built in two versions, one version with extra
 852 debugging messages enabled.  If you are having problems with ISOLINUX,
 853 I would greatly appreciate if you could try out the debugging version
 854 (isolinux-debug.bin) and let me know what it reports.  The debugging
 855 version does not include hybrid mode support (see below.)</p></div>
