I never talk to IBM. My source is "Disk Operating System, Technical
Reference", sold by IBM. I bought it along with PC-DOS. I've seen it
documented elsewhere, also. Just go to your local bookstore, which is
usually jammed with books on MS-DOS, and flip through them till you find
it. I've found Tower Books to have a particularly wide selection of such
books, also university book stores.

The info is not a secret, and isn't that hard to come by.
