> Yes, but how did you draw a line? You did use some library I suppose? I didn't! They were all bitmaps :)

@ghaerr, your description of the challenges fits to the XMS (exTended memory) which indeed requires 286+, not EMS (exPanded memory) which came to the market much earlier and works with...

> Can the UMB card and EMS card be used simultaneously, or is there no space in the UMA? They can be used both simultaneously and I'm using them both,...

@ghaerr seems like I applied modern thinking to an ancient solution (which EMS is). Those DOS programs that use EMS are written with full awareness of what kind of memory...

OT: Some hint on availability of those lo-tech cards (namely, XT-IDE, UMB memory, 2MB EMS memory). Although lo-tech is British, they don't produce their ISA cards (anymore), all of their...

> If the card could be set such that the upper memory start address is just above your machine's exiting (640k?) memory, I am thinking some very simple modifications could...

> I am thinking some very simple modifications could be made that would allow the memory scan performed in setup.S to just add the UMA to the 640k and pass...

> The memory used by the executing kernel is divided into two 64 segments (not allocated, but removed from the overall memory available to seg_alloc); the CS (code) segment, which...

> Remember, there are no pages on the 8086 or ELKS. The data and code segments are of variable size, and not necessarily adjacent, and the code segment can be...

> Yes. ktcp can't utilize hardware flow control because the kernel doesn't support it. Does it mean, `miniterm` started with `-r -d` behaves no different than when started without those...
