I've put up code (ddir.nsm) for a simple dump-directory-names to view
the file list on a booted pdBIOS32 diskette.

That's very neat, and it works! I downloaded and built ddir.nsm
according to the instructions in the comments, copied it to the
pdBIOS32 floppy and it runs fine on the test machine.

It's good to see code written by one of us on aod work with code
written by someone else on aod. I know it "should" work but code which
should and code which does work are not always the same set. I'm sure
it's happened before on this newsgroup but it has to be a rare event.
Something to celebrate, perhaps!

Great to have verification, it's fun to do. The code is still a
kludge. I took the shortcut of _assuming_ the directory location on
the diskette is static. Mike points out the correct algorithm is:

directory LBA = reserved_sector_count + (sectors_per_FAT *
number_of_FATs)

but to implement and test was more time involved than I wanted to
spend at that moment, so consider it as 'demonstration' code - 'quick
and dirty'.

The real kudo's go to Mike, he's put a heck of alot of effort into
pdBIOS32, and shared those efforts.

The 32 bit PM Bios offers a scratch pad basis for trying out your
32bit stuff in a flat memory model. -or a mere diversion to port your
ancient dos code as an exercise, on a day you want a break from your
latest project.

I suppose. If anyone else cares to jump in and do some more fat12
file utilities; rename, erase, create, we would be on the way to an
AOD 32-bit mini dOS.
