Question about filter driver
Posted by on November 26th, 2006


Dear all,
I have a question about the disperf sample. In the services key
the is a sub keu called ENUM. In that key there are 3 entries:
0
count
nextinstance
Can someone explain what this does, what happend it I delete
ENUM sub key?

Next question:
I want to use the sample for my own driver, but I want to have
a different driver/filter name because, aparanetly, disperf is
required to be unchanged in windows. What are all the changes
that I need to make in the registry to change the name.

I have asked this question several times here but I can say that
the support I am receiving is almost zero. Please, if you do not
have the correct answer to my question please please do not
reply. My email is
disperf@btinternet.com

This key is for some internal use by Windows, do not touch it.

The question is, if I create my own disperf, i.e not instead of it but
as an extra filter to disk.sys, then I need to add a Service like it but
for the new one, so I need to have an exact duplicate, right? So do
I need to enter the ENUM subkey as well, since the sample doesn't
have this in the .inf file. Do you understand what I am asking? Please
do not reply if you don't understand my question.
My email is disperf@btinternet.com

Don't worry about ENUM the system will do it. Just take a copy of the
diskperf.inf and replace all occurances of "diskperf" with a new name of 8
characters or less. Also, take the SOURCES file and change the name of
there.

No, it is created automatically by Windows.
