	The recent CHKDSK problem brings up the question "Just how
many MS-DOS 5.00s are there are how can you tell ?" I must admit to
having been buried in antiquity with my studies of antediluvian boot
sectors but this controversy and the accompanying VER /R debacle
brought this up.

	First, I am sure that by now everyone knows that no matter
which version of MS-DOS 5.00 is booted (from the beta 5.00.409c (1990)
to the beta 6.00.0015 (1992)), VER /R returns "Revision A".

	Just checking through my stuff I have found three different
released versions of MS-DOS 5.00 dated 03-22-91, 04-09-91, and
11-11-91. All report simply MS-DOS 5.00 though various components are
different (all COMMAND.COMs COMPare the same @ 47845 bytes & VER is an
internal command).

	For completeness, I would like to know if there are any other
MS-DOS 5.00s out there and is there any differentiation between them
other than date (to spare the group, please reply privately to
padgett@tccslr.dnet.mmc.com, I will post any interesting discoveries).
Please only *real* Microsoft versions - I know of different DOS 5.0s
from IBM, COMPAQ and ZENITH for example.

					Warmly,
						Padgett
