====== MultiBoot Image ======

MultiBoot is a minimalistic self containing linux system designed to solely fit inside the Recovery partition of the AC100.

It offers a multiboot menu thanks to [[http://kexecboot.org|KexecBoot]] project using a modified 2.6.38 kernel. This kernel supports the kexec syscall, so any linux distro can virtually be booted with this MultiBoot image, including Android.
===== Installation =====

==== Where to install ? ====

Although MultiBoot can just be installed in place of the main kernel, but can also be installed on the recovery partition.

Please note that booting a different system through the recovery menu is only supported on the bootloader provided by Android 2.1. If you have upgraded your AC100 to Android 2.2 prior to install linux, it's highly advisable to downgrade your AC100 to Android 2.1 (you do have backups, [[backups|don"t you ?]])

==== Download ====

Official MultiBoot release 1 image is available from there: http://www.pkg.fr/chrome/site/multiboot-r1.img

==== Using nvflash ====

==== From a working AC100 system ====
