- The associated file (EMS40UPD.TXT) contains the three major
- changes between the Lotus/Intel/Microsoft (LIM) Expanded Memory
- Specification (EMS) Version 4.0 that was released in August 1987
- and the "final" version released in October 1987.
-
- This file is provided for those who may have downloaded my
- previous transcription of the specification (LIMEMS40.ARC) and
- who do not wish to download the entire updated specification
- (LIMEMS41.ARC) just to receive all of the updates.
-
- The three major changes between the August and October releases
- were these:
-
- o The example program written in Turbo Pascal was completely
- rewritten (it really needed it!),
-
- o Function 4 (Allocate Pages) was changed so as to no longer
- allow the "allocation" of zero pages,
-
- o Function 27 (Allocate Raw Pages) was respecified to consist
- of two subfunctions:
-
- Allocate Standard Pages subfunction
- Allocate Raw Pages subfunction
-
- The Allocate Standard Pages subfunction is essentially the
- same as Function 4 (Allocate Pages), except that it does
- allow for the allocation of zero pages. The Allocate Raw
- Pages subfunction is substantially the same as the original
- Function 27.
-
- There were many other small changes made, such as changing most
- previous references to Function 4 (Allocate Pages) to now include
- references to Function 27 (Allocate Standard Pages subfunction),
- broadening the scope and explanation of some return codes, and so
- on.
-
- Unfortunately, most of the typographical errors which flawed the
- earlier specification continue to mar the current one, and some
- of the appendices were not fully updated to reflect the Function
- 4 and Function 27 changes.
-
- The complete text of the three major areas of change is contained
- herein in file EMS40UPD.TXT. A complete transcription of the
- corrected and fully updated LIM EMS Version 4.0 document is
- available in file LIMEMS41.ARC.

- DOMAIN WITHOUT ANY GUARANTEES OR WARRANTIES OF ANY
- KIND, AND I ASSUME ABSOLUTELY NO LIABILITY FOR THEIR
- ACCURACY, CONTENT, OR SUBSEQUENT USE.
