Well.. who knows what happens if the NFTL table gets corrupted somehow
due to conflict between the NFTL driver and nftl_format. I would not at
all be supriced if in such case it behaves quite different depending on
which fileset you copy first/how as this has impact on in which order
the blocks is beeing used by the filesystem.

But if you are sure the NFTL driver was removed from the system when you
ran nftl_format then it must be something else..

As of yet I have only formatted our DOC chips using the DFORMAT tool.
Feels like a safer approach. And with the current GRUB patch you should
be able to install GRUB direcly using DFORMAT 5.X as a binary partition
image.

Note: For various reaosns (mainly lack of time and lab equipment to try
out a new scheme) we are still using the msys drivers and a normal grub
loading from the doc via the msys BIOS. Hope to switch to native
Linux/GRUB drivers shortly.
