[...your comments on calling Microsoft and Vesselin's re-posting of

Another way to check the revision of the DOS version is to make use of
the undocumented /R switch in the VER command.  This returns the
version and revision of DOS loaded as well as whether or not DOS is
loaded high.

For example, shelling out to DOS and typing "VER /R" reveals:

  D:\PCPLUS> VER /R

  The Operating System/2 Version is 2.00 
  Revision 6.427
  DOS is not in HMA

Heh heh.. Oops.  Looks like that is also supported by OS/2's DOS emulator.
Let me take another try at that:

  D:\PCPLUS> VER /R

  MS-DOS Version 5.00
  Revision A
  DOS is in low memory

There we go.  As you can see, MS-DOS Version 5.00 Revision A is present.
