Hi Georg,

My port is not a DOS environment emulator, it is just a cross
compiler. The compiler programs (gcc/g++) are real Windows programs,
so they can run in 64-bit Windows. But the outputted executable files
are still pure DOS program, they can't run in 64-bit Windows.

If you want to run your compiled executable program in Windows, I
suggest you can try DOSBox:

http://www.dosbox.com/

I think it is much better than Command Prompt window in Windows.

Can you make BIOS calls on 64bit Windows? Or do I have to replace these with standard DOS calls to make that work?
