Well,

It seems like U want to fight with fire…
There are two books (NT undoc, and win2k Undoc) with NT native services API
book to get you started on it…

I’ve done quite a bit of it, not particularly I like it, but necessity, and
I found it very
very interesting as well as frustrating…

For NT 4.0 it is fairly straight forward, having handy ref. of those books.
For Win 2k,
you will have to play the trick of disabling
page protection of IA-32 bit arch, and to know where the pagetables are
that you can find from Inside Windows 2000 book, and ntndis.com site ). For
XP, the win2ksys seems
like pageable, so it has to be paged in or to make sure it is resident,
before trying to replace the vectored addresses…

Finally not much help you would get, since it is very very very … tricky
and discouged idea, sometime alternatives might be offered by the Big guns
hanging out here…

I particluarly dont mind to scrap these out, as soon as I find altenative
documented ideas.
