hi all
'Juiceme' have made me a special version of ubiboot that has bootup for 2 Nitdroid entries and a Harmattan entry.

Before installing this, fix your system so that your 2 Nitdroid installations are as follows:

Nitdroid alpha 4 is installed in directory /home/nitdroid4
Nitdroid alpha 5 is installed in directory /home/nitdroid5

Then, unpack the file http://www.swagman.org/juice/ubiboot...oubledroid.tar (md5sum = 1ac546b186a7f6d2bdebd6b950eae5b6)
It contains 2 files, the ubiboot kernel and a tar file containing the configuration, CPIO, kernels and preinits.

1. Copy the file doubledroid.tar to your device, and unpack it (as root) with command "tar -xvf doubledroid.tar -C /".
2. flash the kernel zImage_2.6.32.54-ubiboot-02_091113 to your device.
3. Enjoy.
