I've seen a number of programs that map out what resident utilities
are present in memory.  Most return the name of the resident utility,
its size in bytes, and the interrupt vectors it takes over.  I haven't
seen any source code for this, however.

Anyone in net-land know how these programs go about their task?  Is there
a table in memory maintained by DOS of these resident utilites?  Can I call
a DOS function to get a listing?

I need this info so I can tell if a certain memory resident utility is
present in memory when a program is invoked.  Any help would be very
much appreciated..

Thanks,
  Garrett
