    2828=== Original OS ===
    29 Original OS for this device is Ubuntu 9.04 Netbook remix with GNOME as default environment. As it is described <here>, there are some files which doesn't belong to any package. Everything works out of box.
     29Original OS for this device is Ubuntu 9.04 Netbook remix with GNOME as default environment. As it is described [http://wiki.debian.org/InstallingDebianOn/Sharp/PC-Z1NetWalker#UFO here], there are some files which doesn't belong to any package. Freescale Semiconductor provides probably sources for this. Everything works out of box.

     31=== Recovery ===
     32[http://people.debian.org/~osamu/pub/spider-recovery There] is alternative recovery script which can prepare microSD recovery card on other machine. System should be easily recoverable with original bootloader left untouched in NOR flash.

     34=== Notes ===
     35Sleep_Walker started second stage kexec based bootloader for Netwalker (can be found [http://git.hackndev.com/?p=netwalker/initrd-skel.git;a=summary here]) to be able to boot both kernel image and initrd from any supported device (microSD, USB, internal flash, wifi) and to be able to backup or restore internal flash. Unfortunately current kernel sources provided by Ubuntu (jaunty-araneo-kernel) has broken kexec.
