This version of Mtools require the offset parameter in /etc/mtools
(the last parameter for an HD entry, giving the offset to the bootsector,
where filesystem specific information is stored, that are used by Mtools)
to be given in BYTES (only god knows why). Typically the first track on a
(DOS-) HD is reserved, containing only the partition sector. Hence you have to
count your sectors/track and multiply it with your sectorsize.

This works for my one and only DOS partition. I don't know if this holds
true for additional DOS partitions. I suspect some problems, if you have
a large first partition, which requires a very large byte offset to a
second partition (I didn't check the code for datatypes).

Hope this helps
