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:
