DOS Extender - What Is It |

WordPerfect® 5.1 for DOS
Problem
Solutions: DOS Extender - A DOS Extender is part of a program that is too big to fit into the 640K of conventional memory, and needs to run part of the program in extended memory. For example, Lotus 1-2-3 version 3.0/3.1 uses a DOS Extender. Most of the program's code is in the first 640K of memory. It needs more to run, but DOS can only give it up to 640K. Because of this, Lotus has to use a portion of extended memory in order to run the rest of the program. This tricks the program into thinking that DOS has given it more than 640K of memory. This is the DOS Extender. It follows a standard called DPMI (DOS Protected Mode Interface), which is the DOS Extender. |
