I don't have a definitve answer to the question Mike posed, but I can report
one way you *can't* tell which version you have... :-/

The VER/R command returns the following for **both** versions:

        DOS 5.00
        Revision A
        DOS in <low,high> memory

(The wording may not be exact here, but the Revision A part is correct.)
I have tested this on both versions, dates 04-09-91 and 11-11-91.

Since the "Revision A" message appears regardless of version, this is *NOT*
a reliable way to determine which version you have.  To be safe, check the
date.

BTW, by my reckoning, the 65280-cluster limit represents a partition of
about 130 MB.  No small bug, this... :-(

Hope this heads off any confusion or false security...
