DOS extender |
Also found in: Wikipedia | 0.07 sec. |
DOS extenderSoftware that is combined with a DOS application to allow it to run in extended memory (beyond 1MB). To gain access to extended memory, it runs the application in Protected Mode. When the application requests DOS services, the DOS extender either handles them itself or, with functions such as disk accesses, resets the machine to Real Mode, lets DOS service the request and then switches back into Protected Mode. Windows 3.0 included a DOS extender, and although it may seem ridiculous today, by breaking the 1MB limit, Windows solved a very thorny issue and became very popular. See VCPI and DPMI.
