DJGPP v2.x Setup with the DPMI services
DJGPP v2.x gets rid of the extender, and instead requires DPMIservices to run. DPMI, an acronym forDOS Protected-ModeInterface, is a special API that allows protected-mode programs to runon top of DOS. It defines several functions that a protected-modeprogram (calleda DPMI client) can use to perform such tasks asentering protected mode, allocating memory and segment descriptors,calling real-mode services, hooking interrupts, etc. Many modernoperating systems for Intel CPUs include the DPMI services; all versionsof MS-Windows, OS/2, and Linux DOS emulator are notable examples. Thereare also several proprietary DPMI servers for DOS, usually bundled withDOS memory managers such as QEMM and 386MAX; andFreeDOS includes a DPMI server as part of the default setup. For thosesystems which don't have a DPMI server, DJGPP v2.x comes with afree server called CWSDPMI; not surprisingly, CWSDPMI reuses alot of code from go32. The DJGPP startup code checks forDPMI services, and if they aren't available, automatically looks for andloads cwsdpmi.exe, the CWSDPMI server.
The DPMI server (a.k.a.the DPMI host) solves most of theproblems of running a protected-mode program on top of real-mode DOS. The rest of the functionality, which in v1.x was the responsibility ofgo32, is handled in v2.x by the DJGPP startup code andlow-level library functions. Let me now briefly describe these twoaspects of DJGPP operation.
