Real mode or DPMI? IMHO, real mode is doable, DPMI - not so much (at

Did DPMI even exist at this time ?
15 years ago is 1998, so yes. Maybe it was even earlier?
IIRC it was a native 8088 chip -> http://en.wikipedia.org/wiki/Intel_8088
Real mode it is, then. DPMI requires 286+ and the DOS extender that FPC
uses is 386+. Borland Pascal 7 had a 16-bit (286+) DPMI dos extender. We
can implement that as well, as soon as the i8086 large memory model is
finished. The Open Watcom linker we're using already supports the
DOS/16M extender binary format I think.
