Yes, you do.

Your application may make calls to the EMS driver which concern the SMALL
page frame only.  Messing with large frame EMS will screw with Windows'
memory management.  The functions you may call are numbered 1-15, and 18.
Unfortunately, Microsoft did not include a function interface in their
libraries.  I've written one, but I don't think my company would appreciate
me distributing it. :(

Hmm.  The function may not be prototyped in windows.h.  Be sure you declare
it as a FAR PASCAL function in your prototype.

Hope this helps.
