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

SYNOPSIS extlinux [options] directory

DESCRIPTION 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 boot disks.

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:

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.

-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).

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 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 majordomo@linux.kernel.org with the line:
