An [Acronym] for [DOS] ProtectedMode Interface. See the [DPMI API Specification 1.0|http://www.delorie.com/djgpp/doc/dpmi/].
[DPMI] is a programming interface from MicrosoftCorporation that allows programs to run in ProtectedMode under [DOS] while still calling RealMode [DOS] and [BIOS] functions. It also allows multiple ProtectedMode [DOS] programs to run concurrently, eg under Windows 3.x.
-In contrast, while XMS allows storage and retrieval of data and code beyond the first megabyte of memory via its [API], there is no direct access to or execution from beyond that region, because code using XMS still runs in RealMode.

-Then there's also VCPI.. ''(AddToMe: what ''exactly'' was that, again? I only remember the abbreviation vaguely. Plus, VCPI and XMS really need their own pages.
