Thank you very much, too! 😁
Personally, I prefer the method where DOS itself sees contingous memory (borrowed from the UMA).
It would allow for several interesting experiments with older software or with old compilers,
that otherwise would run out of memory a bit too soon.
In essence, the usual video framebuffers and Option ROMs do limit that what otherwise would be contingous memory.
Early PCs, like the once popular (-in Europe-) Siruis 1/Victor 9000, had got about 900kiB free to user applications because of this circumstance,
as its video sub system was differently designed. That's why I think CGA and Hercules (or Hercules InColor) are so fascinating, too.
They were *there* (in those days), but don't inherent the same limitations to the user as EGA/VGA do - at least in terms of the framebuffer area/size. 😀
