About loading drivers

Jack_sa · April 21, 2009, 5:18am

Dear friends

It is possible to load a driver (or filter driver) before other drivers in
boot time? is there any way to start a driver before other installed driver
in boot time ?

Cheers
Jack

This is one of the fav questions on the list.

Answer can be yes or no depending upon what you want to load and before
which driver.

Yes you could make your driver to start before others …
but then somebody else can insert his driver in front of yours

The driver order load process is reasonably well documented. Be careful
of dependencies (eg trying to load an NDIS driver before NDIS is loaded
will cause a crash).

Putting your drivers into their own group and forcing the order of that
group is the only way to be sure, but of course things get tricky if you
want your driver to load before some drivers in one group and after some
other drivers in the same group.

The only particularly tricky thing I have found with group ordering is
that WdfLoadGroup always resets itself to be 3rd in the list, after
“Boot Bus Extender”. I got around this by creating a dummy group that
was 2nd in the list, forcing “Boot Bus Extender” into 3rd place, and
then into 4th place when WdfLoadGroup fixes itself up.

And what happens when a second person comes around and wants to “always” load their driver “first”?

Straight to your question. You may control load order, here is an example:
http://support.microsoft.com/kb/115486

But make sure your driver is compatible with simular drivers, i.e. if it is
filter, it should work normally with or without any third party filters in a
system …

Couple of basic questions to OP.

What does your driver do?
When do you want it to be loaded? i mean before which drivers etc.

Depending on the Symantec driver it will not matter, some of this junk hooks
itself into the system.

SDT Hooking? That’s so last century. Must be malware.

If this is not a trade secret, why? What’s wrong happens if your and their
driver get’s loaded?
