Below Eric explains (may be, there was not the best wording): with mono
adapters/text modes video memory resides at B000 segment. I remain his
sentence, which you place at the end of your letter.
BTW, this raise two questions to Michael Devore:
- may EMM386 autoinclude given region in some way, if there will not be
detected mono adapter/mode? QEMM386 does this.
- what happen if I=B000-B800 will be used on system with mono adapter/mode?

No, unless your system assembled with mono adapter (MDA/Hercules).
