In [[computing]], the '''DOS Protected Mode Interface''' ('''DPMI''') is a specification introduced in 1989 which allows a [[DOS]] program to run in [[protected mode]], giving access to many features of the new PC processors of the time not available in [[real mode]]. It was initially developed by [[Microsoft]] for [[Windows 3.0]], although Microsoft later turned control of the specification over to an industry committee with open membership.<ref name="Duncan_1991"/><ref name="Duncan_1992"/> Almost all modern [[DOS extender]]s are based on DPMI and allow DOS programs to address all memory available in the PC and to run in protected mode (mostly in [[ring (computer security)|ring]] 3, least privileged).<ref name="Schmit_1995"/>
