The .ADF files are the control files used by the Microchanel setup program
on the reference diskette to control the CMOS configuration storage.  They
have nothing to do with DOS except that the reference diskette itself runs
a special version of DOS when you boot it. .ADF files are distributed with
the original Microchannel machine reference diskette, and should be included
with any Microchannel card you buy.  The DOS you run to do interesting work
never sees a .ADF file.

I've been running a production copy of MS-DOS 5.0 for some time on a variety
of machines (Microchannel and ISA) with no problems.  All of these machines
were running PC-DOS 3.3 prior to installing the MS-DOS 5 upgrade.
