you never actually had your hands on a dual system, did you?
or have much knowledge about multiple OS installation, virtual PC's,
Or what is eXtreme Programming about, the theme of the newsgroup you
are posting in?
uh, just asking, ye know, no offense meant.
you see, there are a few things you dont know about:
1) even on a dual board you can run only one OS at a time
if you want a second OS you got to install an emulator
(like Dos-Shell, vmware, virtual PC)
2) if you run the same code on Dos or Windows on the same machine it
wont be noticeable faster on Dos. Windows-programs only seem so much
slower because of the GUI and 'cause they usually do a lot more stuff
in them today then they did in the dos programs.
So moving your computation parts to a Dos program only will add
overhead for communication and much more work for the programmer, so
in the end it will be slower then a windows program.
3) you are absolutely in the wrong group here!
