Hi!
Well, I made additional test how MS-DOS performs INT21/26 (which fields
fills). I fill 100h bytes by AAh, point to this are by CS and perform
INT21/26. Result:

Hi!
Why DosUmbLink() tries to join free blocks (in low memory) when
uppermem_link switched from 1 to 0 (but not when it switched to 1)? I think,
this is wrong: blocks joining should be performed (by RBIL) only for memory
allocation in DosMemAlloc() and DosMemChange() (realloc).
