It has none - else this thread would not've been started in the first place. 

DI10000DD supports 2K sectors for CD/DVD media, and 512-byte sectors only for 
magnetic disks.

My first idea was to look whether I could 'hack' bigger sector support into 
DI1000DD - using IDA to get a disassembly.  Turns out modding the beast without 
a proper source is nothing easy, leave alone the fact that it is certainly not 
legal. I was able to get the int 13 provider right, but that is not the 
interesting or even necessary part. The DOS stuff, recognising, mounting and 
accessing partitions is complex, and the worst nightmare is that the internal 
sector buffer, which would have to be resized, is in the middle of everything 
rather than right at the end (or start) so to mod it one would need a perfect 
disassembly and reassembly, not 'just' some patching here and there. Much to 
learn form but not fit for modding IMO.
