   No. Those are all implemented on the same sort of hard   
   disk - a simple consecutive sequence of fixed size sectors   
   that can be theoretical fread and fseek'ed.   
      
   It's storage that isn't fixed size sectors that I am asking about.

   I think so. Is this what "option ROMs" are for?   
      
   But yeah, the whole point of a BIOS is to separate the hardware   
   from the OS, isn't it? So there's no choice. In the same way that   
   serial ports were added to INT 14H, MO drives need to be added   
   to INT xxH if they aren't already covered by some other INT, like   
   standard INT 13H.
