Yes this option was for those HDD images that assume the 512 byte sectors
where decb could easily access the 256 byte part of the HDBDOS partition.
Though technically there should now be a option to tell decb to support
either.  Cause we have people that use 256 and 512 byte sector images for
use with either SuperIDE or CoCoSDC.
