dskinit code

Hello there,
can any one post the inicialization code of the C6713 DSK "...dskinit.c"
that comes with the book
"Digital Signal Processing and Applications with the C6713 and C6416 DSK"
by Rulph Chassaing. I don't have the cd because I lost my laptop with the
cd and all the code that I made. Now I have to do everthing again...
Thanks a lot.

I have the CD and files, let me know, I may be able to get them to you if
you still need them.
