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 sim-
plify first-time installation of Linux, and for creation of rescue and other special-pur-
pose 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
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).
The extlinux configuration file needs to be named 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 SYSLINUX, especially if you are using it for a
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 firstname.lastname@example.org with the line:
