See the functions `enable' and `disable'.  Note that interrupts could
still happen (for instance, if a page of your buffer needs to be swapped
in).  You might consider locking your memory (with __dpmi functions, or
the crt0 flag (which is simpler though inflexible)).  And of course,
under Windows or another multitasker, it won't really disable interrupts
at all.
