If you have put MeeGo on N900 image on your microSD, using the flasher, you can then dual-boot using this command line:
flasher-3.5 -k vmlinuz-file -l -b
You can download a MeeGo for N900 vmlinuz/kernel from one of the releases.
Turn off your N900, plug the USB cable into your PC, and the flasher will make the N900 load the kernel over USB and boot into MeeGo, provided the microSD is put into your N900 and the back cover closed. This operation is a one time thing and does not alter your kernel on the device.
Under construction. This feature is not working in MeeGo due to kexec problems
Some additional packages are required to be installed to your Fremantle installation to get the dual boot working. This includes kexec-tools, kernel with kexec support and bootmenu.
kexec-tools can be installed from Fremantle Extras-devel repository (Browse,Install). After installing the repository, you can install the package:
apt-get install kexec-tools
To boot MeeGo from your Fremantle installation, you need to install a kernel that supports kexec, that can be found from HERE.
If you wish to have a boot menu to select either Fremantle or MeeGo during boot, you need to install bootmenu to your device (located also in the Extras-devel repository):
apt-get install bootmenu-n900
After installing the bootmenu, go to the application menu and click the "Install Bootmenu" icon. If you really want to install the bootmenu, type yes to the question.
Now you should have a functional bootmenu on your device. You can try it out by rebooting the device and keeping the keypad slide out during the boot.
Next, we need to add a new item to the bootmenu for the MeeGo. Add the following lines to /etc/bootmenu.d/meego.ext.item
ITEM_NAME="MeeGo (external SD, partition 1)"
ITEM_ID="meego"
ITEM_DEVICE="${EXT_CARD}p1"
ITEM_MODULES="mbcache jbd ext3"
ITEM_FSTYPE="ext3"
ITEM_FSOPTIONS="noatime,rw"
Next, we install MeeGo to an external micro SD card (size >= 2G). NOTE: The content of the card will be deleted, so copy all essential data to a safe location before continuing.
The image can be written with ...
You can boot to MeeGo with bootmenu (if installed) or with kexec command.
