Please see the included file COPYING for details. + +---------------------------------------------------------------------- + +ISOLINUX is a boot loader for Linux/i386 that operates off ISO 9660/El +Torito CD-ROMs in "no emulation" mode. This avoids the need to create +an "emulation disk image" with limited space (for "floppy emulation") +or compatibility problems (for "hard disk emulation".) + +This documentation isn't here yet, but here is enough that you should +be able to test it out: + +Make sure you have a recent enough version of mkisofs. I recommend +mkisofs 1.13 (distributed with the cdrecord distribution), but 1.12 +might work as well (not tested.) + +To create an image, put isolinux.bin, a config file called +"isolinux.cfg" (see syslinux.doc for details on the configuration +file), and all necessary files (kernels, initrd, display files, etc.) +in the root directory of your ISO master file tree. Then use the +following command to create your ISO image (add additional options as +appropriate): + + mkisofs -o -b isolinux.bin -c .boot.cat \ + -no-emul-boot -boot-load-size 4 -boot-info-table \ + + +The real release version of ISOLINUX will probably look for a +directory named "isolinux" in the root, and use it instead of the root +directory if present. + +Like SYSLINUX, ISOLINUX does not support subdirectories. Unlike +SYSLINUX, there isn't a fundamental reason for this, so if this is +something desirable, let me know and I'll add it on my list of things +to do. + +Note that ISOLINUX only uses the "plain" ISO 9660 filenames, i.e. it +does not support Rock Ridge or Joliet filenames. It can still be used +on a disk which uses Rock Ridge and/or Joliet extensions, of course. +Under Linux, you can verify the plain filenames by mounting with the +"-o norock,nojoliet" option to the mount command. Note, however, that +ISOLINUX does support "long" (level 2) ISO 9660 plain filenames, so if +compatibility with short-names-only operating systems like MS-DOS is +not an issue, you can use the "-l" or "-iso-level 2" option to mkisofs +to generate long (up to 31 characters) plain filenames. + + + \ No newline at end of file
