I can't believe I'm the first person to write this. At least I
think I am. If I'm wrong, let me know.
This little crock displays the sector allocation on your floppy
disks. If the box is colored in, the sector is allocated. I cooked this up
in roughly a couple of evenings.
This was written for the Manx compiler. Conversion to Lettuce
should be trivial. To make this beastie, you say:
1> cc dm.c
1> ln dm.o -lc -o dm
Naturally, if you keep lots of stuff in RAM:, you'll do this
differently.
The DOS manuals give *no* explanation on how the disk sector bitmap
works. None. Nada. Zero. Zilch. Zippo. NULL. (read my lips: none!)
So I pulled out 'DiskEd' and stared at the raw bitmap in hex for a while
until I saw what was going on. I've included a very brief comment on how it
works in the code.
If someone at C-A sees this, could you please tell me if I got this
right? Like I said, the manuals were no help at all.
Have fun with your new crock.
