- 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...
