You can't just issue an INT instruction which calls a software interrupt 
for which a protected-mode handler hasn't been installed.  The error 
message tells you that this interrupt is not supported (i.e. unhandled).  
the right way to do it is by calling the __dpmi_int() library function 
(look it up in the libc docs) which calls the DPMI server to simulate a 
real-mode interrupt from the protected mode.

You might consider reading section 18.1 of the DJGPP FAQ list (available 
as faq200b.zip from the same place you get DJGPP) for further details 
about this matter.
