I think something like a DOS extender? No. It's an interface supported by memory managers for the benefit of DOS extenders working in 'raw' DOS. It's a foundation to build a DOS extender on, not a DOS extender itself. The original design actually came from the firms doing DOS extenders, IIRC. DJGPP V1 had a VCPI-based DOS extender, go32.exe. Later, that was ported to work with DPMI, if that was available. In V2, VCPI support was dropped, because Windows platforms only supporting DPMI became overwhelmingly important, and we couldn't keep supporting both platforms without major pain in the lower back. -- Hans-Bernhard Broeker (broeker AT physik DOT rwth-aachen DOT de) Even if all the snow were burnt, ashes would remain.
