       unsigned char tip;
       r.h.ah = 0xC0;
       int86x(0x15, &r, &r, &s);
       tip = peekb(s.es, r.x.bx + 2);
       printf("computer model:\n");
       switch(tip)
         { case 0xFF: printf("Origin IBM PC\n"); break;

    Are you running this in real original DOS or in a Command Prompt on Windows - if the latter, it is highly likely that you don't get anything because you can't necessarily read the BIOS memory from a Windows command prompt.

    Compilers can produce warnings - make the compiler programmers happy: Use them!
