You can't generate real mode interrupts directly. You have to use DPMI
function 0x300 instead. See below.

Use either __dpmi_int() or __dpmi_simulate_real_mode_interrupt() functions.
These will call the DPMI function for you. See the libc.info documentation
and chapter 18 of the DJGPP faq for details on using these functions.
