Does anybody out there have knowledge of MS-DOS ver 3.2 internals?
In particular, I need to find the device-driver chain and the
drive table. I have an old program from the net (LDEVS) which
works for 2.15 and 3.1, but fails miserably for 3.2.

I believe that there might be a system call (int 21H) that will
return interesting DOS internal addresses, but my "Systems Programmer's
Guide" does not list it (the book has no version #, but only includes things
that are pre 3.0).

Thanks.
