EXTLINUX/SYSLINUX Installation and Configuration

EXTLINUX is the default boot-loader for Praxis, configuration is done manually. This package is installed by default

Installing the Boot-Loader EXTLINUX

For good measure we update the MBR of the disk, this can be done while the disk is in use.

root@host # dd if=/usr/share/syslinux/mbr.bin of=/dev/sda bs=512 count=1

Ensure the /boot partition (if one was made) is mounted and install EXTLINUX.

root@host # extlinux --install /boot

EXTLINUX in the 3.x series creates a file named extlinux.sys.

root@host # ls -alh /boot/extlinux.sys
-r--r--r--  1 root root  13K Feb 25  2010 /boot/extlinux.sys

root@host # lsattr /boot/extlinux.sys
----i---------- /boot/extlinux.sys

In the 4.x series the file is now ldlinux.sys, notice these files are immutable.

root@host # ls -alh /boot/ldlinux.sys
-r--r--r-- 1 root root 32K Oct 30 13:35 /boot/ldlinux.sys

root@host # lsattr /boot/ldlinux.sys
----i---------- /boot/ldlinux.sys

Convert GTP to MBR

Some machines have a feature called UEFI which works with GPT. To convert this system back to using MBR we use gpartd.

emerge sys-apps/gptfdisk sys-block/parted
parted /dev/sda

Configuring EXTLINUX

EXTLINUX is governed by either extlinux.conf (3.x) or syslinux.cfg (4.x) depending on your version.
