My erase block size is 8KB (I'm using a 8MB DiskOnChip 2000), so this
should be no problem. I also tried an offset of 98304 anyway, but this
didn't change anything.

Sorry, I forgot to write, that I did reboot my system.

This is a nice Howto! I wish I had found this earlier. It could have saved
several hours. I did everything as described in this howto, but I still
can't
boot from DoC.
As I already wrote, the kernel is loaded from DoC (using GRub) but I
can't use the root-filesystem, which I have copied there. I CAN use
root-FS on NFS or FDD. I also do have acces to my DoC when I boot
with root-NFS.
I absolutely don't know what to do. Here is what is "dmesg" said after I
booted from NFS. Perhaps someone can tell me, what went wrong.
