   You can tell I don't speak fluent x86.  This is definitely a 6502-flavored

   The next thing I need to do is figure out the "device issue" in a way that   
   makes it look like an Apple ][ (e.g., A: as device 6).   
      
   By making some tweaks to the floppy bootloader I went from being able to   
   load about 32K (which is probably more than enough, given the size of   
   ProDOS-8 2.0.3) to theoretically being able to load 128K, which would   
   almost be big enough to run the later versions of MS-DOS.  Better safe   
   than sorry...
