No -- the DFORMAT program is actually doing something called a "NFTL format", 
which is different than the normal partitioning and formatting.  This can be 
thought of as a low-level format, related to the nand flash chips used on the 
DoC.

Using GRUB doesn't make any difference -- in fact, the instructions for 
putting Grub on the DoC are more complicated than necessary because of this 
problem.

With unmodified modules from 2.4.19, I can mount the DoC twice, read and 
write to either mount point, and everything seems fine.  I believe that 
nftlcore.c is newer than the version included in 2.4.18.

I've been using nftlmount.c (1.28) and nftlcore.c (1.86) to make things work 
with the 5.X dformat.  These versions are even newer than the ones in 2.4.19.

Thank you, Brad.  I've been wanting to put Bering on a DoC for awhile now, 
your instructions certainly made it easier.
