       extlinux - install the SYSLINUX bootloader on a ext2/ext3 filesystem

       extlinux [options] directory

       EXTLINUX is a new syslinux derivative, which boots from a Linux ext2/ext3 filesystem.  It works the same way as
       SYSLINUX, with a few slight modifications.  It is intended to simplify first-time installation  of  Linux,  and
       for creation of rescue and other special-purpose boot disks.

       The  installer  is designed to be run on a mounted directory.  For example, if you have an ext2 or ext3 usb key
       mounted on /mnt, you can run the following command:

              extlinux --install /mnt

       -H, --heads=#
              Force the number of heads.

       -i, --install
              Install over the current bootsector.

       -O, --clear-once
              Clear the boot-once command.

       -o, --once=command
              Execute a command once upon boot.

       -M, --menu-save=label
              Set the label to select as default on the next boot

       -r, --raid
              Fall back to the next device on boot failure.

              Reset auxiliary data.

       -S, --sectors=#
              Force the number of sectors per track.

       -U, --update
              Updates a previous EXTLINUX installation.

       -z, --zip
              Force zipdrive geometry (-H 64 -S 32).

              Override the automatic detection of device names.  This option is intended for special environments only
              and  should not be used by normal users.  Misuse of this option can cause disk corruption and lost data.

       The extlinux configuration file needs to be named syslinux.cfg or extlinux.conf and needs to be stored  in  the
       extlinux installation directory. For more information about the contents of extlinux.conf, see syslinux(1) man-
       page, section files.

       I would appreciate hearing of any problems you have with SYSLINUX.  I would also like to hear from you  if  you
       have successfully used SYSLINUX, especially if you are using it for a distribution.

       If  you  are  reporting  problems, please include all possible information about your system and your BIOS; the
       vast majority of all problems reported turn out to be BIOS or hardware bugs, and I need as much information  as
       possible in order to diagnose the problems.

       There  is a mailing list for discussion among SYSLINUX users and for announcements of new and test versions. To
       join, send a message to with the line:
