I want to access 0xFFA80000 using DOS 6.22

This is the previous code which worked for 0xD00000 ... How can I
define the address so it won't crash.

  if (!__djgpp_nearptr_enable()) {
       printf("    Error : Can't Enable Nearptr!!!\n");
       choice = 'X'; /* leave the loop */
   } else {

       tm = (void *) (__djgpp_conventional_base + 0xD0000);
       sa = (TM_TYPE_SERVICE_AREA *) (__djgpp_conventional_base +
0xD3C00);
   }
