This will as you assume erase the BIOS from the DOC.

If you want to be able to access the DOC from DOS without first booting 
from another media and loading a separate DOS DOC driver you need to use 
the mSYS DOC BIOS, installed by running DFORMAT from DOS.

However, using the mSYS 5.1.5 DOS driver (I think, not entirely sure about 
version but a 5 something) I could not make it function reliably if the 
DOC had been partitioned with more than one partition.. No such problems 
with the Linux driver.
