You can't use debuggers with an emulator if I remember correctly.. Does your program use floating point? If it does not, this might work: 1) SET 387=N 2) Rename EMU387.DXE so it's not found. See if you can debug. I believe this should avoid all FP instructions. If it does use floating point I think you are stuck, since the emulator doesn't know how to handle floating traps in a different address space. As always, you should check the FAQ for additional hints. A conventional TSR emulator won't work.
