This int makes your program totally broken.

:         andl $255,%%eax
:         movl %%eax,%0
:         movl $3072,%%eax
:         int $33

This one too. I'm very surprised it didn't crash. You can't do int
like that when in protected mode. Read the FAQ and the documentation
for __dpmi_int().


Right,
