Here's a quick solution I can think of... Perhaps there may be a simpler
one, but....

Write a TSR to hook INT 15h/88H and make it return some small
number in the AH when someone requests this call. But this method
will work only in raw mode (without HIMEM/EMM386).

I don't think it would be useful to everyone, except those who work mostly
at the system level, and perhaps Charles himself for his testing work ;-).
