release don`t appear

[aska]

hi i write a program to determine the type of IBM and bios level ,the compiler indicate 0 error but nothing appear in release ; this my prog

#include<stdio.h>
#include<dos.h>
void main(void)
 { union REGS r;
   struct SREGS s;
   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;
       case 0xFE: printf("IBM PC XT or portativ PC\n"); break;
       case 0xFD: printf("IBM PC jr\n"); break;
       case 0xFC: printf("IBM PC AT (or XT model 286"
                          " or PS/2 model 50/60)\n"); break;
       case 0xFB: printf("IBM PC XT с 640K memory "
                         "mother bord\n"); break;
       case 0xFA: printf("PS/2 model 30\n"); break;
       case 0xF9: printf("Convertible PC\n"); break;
       case 0xF8: printf("PS/2 model 80\n"); break;
       default:   printf("Unknown type IBM PC\n");
      }
   printf("\n Kod submodel %X\n", peekb(s.es, r.x.bx + 3));
   printf("\n BIOS LEVEL %X\n", peekb(s.es, r.x.bx + 4));
 }

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.
