Here's one that I have found to work on IBM's, Wyse's, NCR's, Zenith's,
Compaq's, etc.:

#define TRUE  1
#define FALSE 0

int CheckForEnhanced(void)
{
   unsigned char far *p;
   p = (unsigned char far *) 0x00400096;

   if (*p & 0x10)    /* is it an enhanced keyboard? */
      return(TRUE);  /* yep, let caller know      */

   return(FALSE);    /* must not be enhanced        */
}

int main(void)
{
   if (CheckForEnhanced())
      printf("Enhanced!\n");
   else
      printf("Not Enhanced!\n");
   return(0);
}

Hope it helps!

-Bill
