 ===== Installation =====
-==== Using nvflash ====
+==== Where to install ? ====
+Although SOSBoot can be installed in place of the main kernel, it's the most useful when installed on the recovery partition (5-th partition in terms of nvflash). So that the AC100 boots by default your favorite OS, and SOSBoot stays available as a recovery system in case something goes badly wrong.
+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 SOSBoot images are available from there: http://share.grandou.net/ac100/sosboot/
+sosboot-r4.img  latest for now.
+==== To clean ac100 using external computer ====
+Using [[nvflash]]
+<code>
+nvflash --bl harmony/fastboot.bin --sync
+nvflash -r --download 5 sosboot.img
+</code>
 ==== From a working AC100 system ====
+check that your sos partition is /dev/mmcblk0p1
+  abootimg -i /dev/mmcblk0p1
+and install it:
+  dd if=sosboot.img of=/dev/mmcblk0p1
 ===== Usage =====
+Power on you ac100 with "Home" key pressed, press 1 in the boot menu.
 ===== Tips and Tricks =====
