NAME

6       extlinux - install the SYSLINUX bootloader on a ext2/ext3 filesystem
7

SYNOPSIS

9       extlinux [options] directory
10

DESCRIPTION

12       EXTLINUX  is  a  new  syslinux  derivative,  which  boots  from a Linux
13       ext2/ext3 filesystem.  It works the same way as SYSLINUX,  with  a  few
14       slight  modifications.  It is intended to simplify first-time installa‐
15       tion of Linux, and for creation of  rescue  and  other  special-purpose
16       boot disks.
17
18       The  installer is designed to be run on a mounted directory.  For exam‐
19       ple, if you have an ext2 or ext3 usb key mounted on /mnt, you  can  run
20       the following command:
21
22              extlinux --install /mnt
23

39

41              Fall back to the next device on boot failure.

57              is intended for special environments only and should not be used
58              by  normal  users.  Misuse of this option can cause disk corrup‐
59              tion and lost data.

FILES

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

BUGS

68       I  would  appreciate hearing of any problems you have with SYSLINUX.  I
69       would also like to hear from you if you  have  successfully  used  SYS‐
70       LINUX, especially if you are using it for a distribution.
71
72       If  you are reporting problems, please include all possible information
73       about your system and your BIOS; the  vast  majority  of  all  problems
74       reported  turn  out  to  be  BIOS  or hardware bugs, and I need as much
75       information as possible in order to diagnose the problems.
76
77       There is a mailing list for discussion among  SYSLINUX  users  and  for
78       announcements  of  new  and  test  versions. To join, send a message to
79       majordomo@linux.kernel.org with the line:
