- When I first installed EMS in my 286, everything worked swimmingly
- _except_ when I had to exit from NB; on those occasions, the system
- would lock up hard, requiring a hardware reset. I was using 4dos
- and swapping to EMS, and I determined that NB overwrote my EMS page
- frame. This didn't cause any problem within NB itself, but when I
- would exit NB, 4dos would be unable to unswap itself from the area NB
- had trashed. Moving my page frame up from the c000 segment to c400
- cured the problem.
-
- At my request (well, more like insistence), Dragonfly reviewed their
- code and insisted that they weren't writing to any addresses they
- shouldn't be. I think they are mistaken and that the symptoms speak
- for themselves.
-
- I have nothing to suggest beyond steering clear of various upper
- memory addresses and seeing if it helps. I harbor a hope that
- NB 4 will have fixed the problem; Dragonfly doesn't know that it
- _is_ their problem, but the rewriting that underlies version 4 might
- have some beneficial side effects. Of course, my first hope is that
- there _will_ be a NB 4 (it's the end of the month - we're allowed to
- fuss :-) ).
