This was the case I had no clue about.  So there is no
default-unless-otherwise-defined amount. Makes sense, in a way.

Last time I had OS2MEMU up, the D parameter was working as advertised
- but I also have a couple of FAT partitions.  That may impact the
assignment as opposed to floppy-only systems.

As expected.

Thanks for the info, Murray.  I've been too busy to get around to
re-booting to check for myself.
