- Does not the DOS programmer need to know about segment:offset
- addressing, what memory model to use, and when ? Can one program
- effectively on DOS without that knowledge ?
-
- How about the differences between 286/386 ?
-
- How about the 640k limit and how to overcome it ? Need not the
- programmer know about extended/expanded memory, DPMI/VCPI interfaces ?
- I have in front of me the second edition (1992) of the book
- "Extending DOS - A Programmer's Guide to Protected Mode DOS" by
- Ray Duncan. The first introductory chapter include detailed description
- of selectors, descriptors etc.
