there are many "undocumented" calls - NtSetInformationProcess appears to be one of them...

I had found this one actually explains why MS(Arun Kishan) castrated the OS. :(

Ok, so I have to declare this approach "impossible". :(

Let see an other way! :bg

I had learned writing drivers from this collection:

http://pr0g.free.fr/fichiers/APJ/

In

http://pr0g.free.fr/fichiers/APJ/APJ-2004-152.pdf

starting page 19 is the "giveio" driver explained.

It works perfectly.
It sets the I/O permission bitmap for certain ports can get access from user level.

I like to rewrite this driver for 64-bit. ::)

But there are some problems.

1.) I had not jet even wrote a "Hello World" for 64-bit. :bg
2.) I know you have to get the driver signed by MS. :snooty: But there must be a go around!

I am willing to do 1 (and of curse rewrite the driver) if 2 is possible.
And I hope I can get some help if I got bogged down. :toothy
