Does anybody knows how can i hook the handler of an hardware interrupt ?

I tried to use __dpmi_set_protected_mode_interrupt_vector with the
following handler 

void my_IRQ5_handler(void)
{
  asm("mov  $0x20,%dx");
  asm("mov  $0x20,%al");
  asm("out  %al,%dx");
  asm("iret");
}

but it don't works :(
