NAME

       extlinux - install the SYSLINUX bootloader on a ext2/ext3/ext4/btrfs filesystem

SYNOPSIS

       extlinux [options] directory

DESCRIPTION

       EXTLINUX  is  a new syslinux derivative, which boots from a Linux ext2/ext3/ext4 or btrfs 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, ext3,
       ext4, or btrfs usb key mounted on /mnt, you can run the following command:

              extlinux --install /mnt

OPTIONS

       -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-adv
              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).

       --device=devicename
              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.

FILES

       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) manpage, section files.

BUGS

       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 majordomo@linux.kernel.org with the line:
