I already used over 700MB on the card, w/ tons of app. That's why people buy large SD card. I bought mine 8GB SDHC for like $70, and it work flowlessly. Just a warning, you can't use SDHC card w/ the stock kernel, at least not yet anyway. The next upgrade will persumably support it, as people are already start using them
What size should be the FAT partition? I assume, the 256mb min is according to the ext2 partition...
Thanks again.

You can mount ext3 without turning on Journaling. You just need to edit the mount options for the partition. I just wondered if anyone was though.

And no, it isn't that bad. This continuous writing problem is a myth. There are a bit more writes indeed for metadata journaling but not something significant.

Hmm... I just tried the procedure to boot from SD card.
I used the maemo wiki:
http://maemo.org/maemowiki/HowTo_EAS..._From_MMC_card
and followed exactly these instructions.
The bootmenu consists of:
boot from flash
mmc
mmc2, partition 2, ext2
...
I get the error : Boot from mmc failed, booting from flash...
when choosing the option "mmc2,partition 2..."
When choosing "mmc" it boots, but boots from flash...
What's wrong?
Some specs:
N800 latest firmware
internal sd card, 2gb
mmcblkp1 ~1.5gb FAT16
mmcblkp2 ~0.5gb ext2
Partitioning done with sfdisk: http://maemo.org/maemowiki/HowTo_EAS..._your_MMC_card
I realized that the instructions from the wiki differ from the one at the beginning of this thread. In this thread used:
What's the meaning of these steps?
EDIT:
While partitioning my SD card with sfdisk it asks me whether I want to mark the Fat16 partition as active or not. I chose yes (to mark as active). Was this decision ok?

vi /mnt/initfs/bootmenu.sh
Change the line
GETKEY="evkey -u -t 1000 /dev/input/event1"
to
GETKEY="evkey -u -t 1000 /dev/input/event2"

the evkey entry is only to get the menu KEYS to work, if you can toggle which menu entry to choose evkey is working for you. Partiton info looks right, my guess would be your data was not properly copied.
did you do this?
# apt-get -d install tar
# cd /var/cache/apt/archives/
# mkdir /tar-temp/
# dpkg -x tar*.deb /tar-temp/
# /tar-temp/bin/tar cf - -C /floppy . | /tar-temp/bin/tar xvf - -C /opt
/bin/tar (busybox) will not copy things properly. If it can not boot from mmc it will boot from flash I believe. http://penguinbait.com/tar.gz is the one I use.

hmmm... I've just booted from flash, inserted mbcache.ko, ext2.ko and mounted /dev/mmcblk0p2. The mountpoint is empty, so I can assume that the cloning progress went wrong. I did exactly the same as described on the wiki:
I just pasted(not very famillar with those tar options...):
and before that, of curse:
I just pasted(not very famillar with those tar options...):
/tar-temp/bin/tar cf - -C /floppy . | /tar-temp/bin/tar xvf - -C /opt
mount /dev/mmcblk0p2 /opt ;
mount -t jffs2 /dev/mtdblock4 /floppy -o rw,rpsize=1024,rpuid=0,rpuid=30000

Yes I did that. Hmmm what can I do now?
EDIT:
I just mounted the card to /opt and initfs to /floppy again to do the try the cloning process again. I checked with df ang got a strange result:
According to this, there is data on the card. But I can't see it....
tells me, there is no data.
