</div>Hi Bernhard,<br>
Wow - but earlier posts (in this very thread, I think) implied that<br>
this was not possible - to boot from an ext3 partition by treating it<br>
as ext2...<br>
Well, I did my sdcard partition as ext2, but I think I need to read up<br>
about ext3/ext2 to understand what you have said. Thanks for the info!<br>
<br>
Regards<br>
