SYNOPSISextlinux [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 installa‐
tion of Linux, and for creation of rescue and other special-purpose
The installer is designed to be run on a mounted directory. For exam‐
ple, if you have an ext2 or ext3 usb key mounted on /mnt, you can run
the following command:
Force the number of heads.
Install over the current bootsector.
Clear the boot-once command.
Execute a command once upon boot.
Set the label to select as default on the next boot
Fall back to the next device on boot failure.
Reset auxiliary data.
Force the number of sectors per track.
Updates a previous EXTLINUX installation.
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 corrup‐
tion 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) manpage, 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 SYS‐
LINUX, 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
