I currently have Maemo with NitDroid installed on my N900 using the http://www.nitdroid.com/index.php?ti...-Autoinstaller.

I would like to Tri-boot my device by adding Meego also on the same MMC and hence would request you to Provide with detail steps to be followed to have this thing happen.

I would prefer the Meego 1.2 DE edtion released recently as per the below info from Nokia - Jukka Eklund.

MeeGo for N900

Submitted by Jukka Eklund on 19 May, 2011 - 21:12.


Thanks for the mention Ross! Indeed we are targeting to have a release of N900 DevEdition available for the Conference, and it is built on top of final MeeGo 1.2. But it doesn't stop there, as there seems to be community interest it will continue evolving.

You can find "vanilla" MeeGo 1.2 images here, also for N900: http://repo.meego.com/MeeGo/builds/s...0.0.20110517.1.... But like you said for N900, the DevEdition might be interesting since it has additional applications, contributions and fixes. You can find the main wiki page now at: http://wiki.meego.com/N900.

I will be at the Conference as well, and hoping to have good discussions around this topic! My presentation is here: http://sf2011.meego.com/program/sess...r-edition-noki...

Also note i have the below mentioned apps (with respect to booting) installed on my device do i need to remove any of them which may not be required.

1) Enhanced boot loader for Maemo
2) Linux Kernel for power user
3) Linux Kernel for power user (boot image)
4) Maemo 5 PR1.2 kernel for multiboot

both linux kernel are power47.

Regards

  I can supply a prebuild file if someone wants it (and have a public area where drop it)
• Save the obtained kernel file in /boot/multiboot with name vmlinuz-2.6.28.10-power47 (replacing existing file that you must have if you are already using multiboot with power kernel)
• Reboot to Maemo with original kernel or to Nitdroid
• Reboot to Maemo with power kernel.
  This will reflash kernel and so will activate/install u-boot

You will have U-Boot only when you will be under power kernel.
Off Couse U-Boot can be added to Maemo's Original kernel and to Nitroid's Kernel too.

How to boot to MeeGo:

• Download MeeGo's Disk Image (kernel file is not needed) and write it to MicroSD, off course if you don't have already a prepared MicroSD with MeeGo
• If you are under Nitdroid's or under Maemo's original kernel, reboot your phone and choose Power kernel
• Shutdown your phone under power kernel
• Power On your N900 with keyboard opened

How to show Multiboot's Menu (i.e. to choose with which OS boot):

• Shutdown or Reboot your phone
• If you rebooted/shutdown under Nitdroid's or under Maemo's original kernel, power on your N900 with keyboard opened.
  Otherwise (u-boot power kernel) keep the keyboard closed to prevent MeeGo autostart
• If U-Boot appears wait until it writes "loading kernel image ... OK" and then immediately open the keyboard to activate/show multiboot's menu before booting sequence can start

I'm using an sdcard recently vacated by nitrdroid after I moved it to the emmc. Does the meego image need to be weitten to the fat32 partition or does it need the ext3 partition formerly used by nitdroid?

MeeGo DE uses EXT4 for its main partition

ITEM_DEVICE=${EXT_CARD}p1
