Yep.  This is the ideal approach.  I have had no success so far
in finding out how.  The NT programming newsgroup appears to 
be all clueless newbies.  There is a lot of activity, but 
no responses.  Everything I have seen so far about interrupts in the docs
involves there relation to the HAL.  Also, nothing about chaining an
interrupt, just grabbing it exclusively.  I will continue looking though.
The manuals that come with ms c and the dev kits just suck. Even 
the search routines don't work well.  Worse, they aren't hyperlinked.
It will highlight other sections, but clicking on it doesn't take you 
anywhere.

I'll try it out.

I've gotten the BOPping method to actually work somewhat.  I can
pass in a asciiz file name and have NT convert it automatically
to its short form.  The other functions should be trivial.  
Getting a good interface should be all thats left.
