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:
