N900 install NITDroid Gingerbread on SDcard simply
   
    I tried to use N900-Autoinstaller here: http://wiki.nitdroid.com/index.php?title=N900-Autoinstaller But failed。
    The guid N900-install here: http://wiki.nitdroid.com/index.php?title=N900-install is outdated, some of the packages can't downloaded.

    I have installed Gingerbread on my N900 with the following steps:

1. Prepare SDcard 

    For this step you need to know the capacity of your SDcard. The Android partition can only be 2GB, so you need to create a FAT partition that is so large there will only be 2GB left. The number must be in MB, example some recommended sizes are 1, 100, 2100, 6100, 14100, 30100. If its 8GB you can choose a number like 6100MB, if its 4GB you can choose a number like 2100MB. If your memory card is 2GB or below, you can choose 1MB as a number. I suggest you use 4GB or bigger.

    Here's an example using 4GB SDcard, use these commands in your N900:

# sudo gainroot
# umount /dev/mmcblk1p1   
# sfdisk -uM /dev/mmcblk1 << EOF
,2100,C
,,L
,,
,,
EOF

2. Install the packages that are needed during the installing

# apt-get install wget bzip2 multiboot multiboot-kernel-maemo

or download these packages and install.
from http://maemo.org/packages/:
wget_1.10.2-2osso3_armel.deb
bzip2_1.0.5-3+0m5_armel.deb
multiboot_0.2.10_armel.deb
multiboot-kernel-maemo_0.3-1_armel.deb


3. Install android filesystem and kernel

# cd /home/user/MyDocs
# wget http://downloads.nitdroid.com/e-yes/gingerbread.tar.bz2
# bzip2 -d gingerbread.tar.bz2
# mkdir -p /and
# mount /dev/mmcblk1p2 /and
# cd /and
# rm -rf *
# tar xvf /home/user/MyDocs/gingerbread.tar

# cd /home/user/MyDocs
# wget http://downloads.nitdroid.com/nitinstaller/Packages/nitdroid-kernel-2.6.28-06_final1_armel.deb
# dpkg -i nitdroid-kernel-2.6.28-06_final1_armel.deb

4. Reboot and enjoy android

# reboot
choose 2 to boot android
