What is that first function--is that __dpmi_physical_address_mapping?

If that fails, you cannot continue.

What are the values of dmi.start and dmi.length printed by this
snippet from your program:

>   mi.address = dmi.start;
>   mi.size    = dmi.length;
> 
>   printf ("mi.address = %08X\n", dmi.start);
>   printf ("mi.size    = %08X\n", dmi.length);
> 
>   if (__dpmi_physical_address_mapping (&mi) == -1)
