I trying to re-compile a very, very, very old Project written for the Archimedes Compiler Version 4. It was created by an employee that is no longer with the company. The Target CPU is a Siemens 80535, an enhanced 8051 CPU, and a single 27C512 EPROM. When I run the MAKE File it calls C:\arch4\bin\c-51 (an .EXE file dated 11/14/1990!). I am trying to compile in a DOS window in Windows 2000. I am told that the orignal programmer used a DOS window in Windows 3.0 for compiling. Any help in how to prevent the "DOS/16M Error: [30] Program must be built -AUTO for DPMI" ERROR Message? This Embedded application has no idea what DOS/16M or DPMI is and could never use that functionality.
