- NDIS miniport driver
- Posted by Michal Filka on April 19th, 2005
Hi all,
I've following problem. I need low level access to NIC, so I want to create
own NDIS miniport driver.
Questions are:
- is it possible to have two NDIS miniports running for one card in one time
(one which drives card, sends packets and so on = manages normal traffic ...
and second one which is responsible for running my own NIC's commands
sequence and nothing else)?
- I suppose that driver responsible for normal traffic should be "suspended"
during working time of the second one. Is that true?
Thanks for your time ...
Michal

Even that possible to stop OEM miniport driver and start yours and v.v. , do
you know how to talk to OEM's firmware ?

Hi,
Can you please elaborate what is your "command sequence"?
Does it talk directly to hardware?
You can stop the normal NIC driver, then replace it with yours and start the
device. Then swap your driver in again. But not two drivers at the same time.

Hi,
in original driver.
.... and what about original driver initialization if I swap it back? Is it
done again?

I hope so. However, I don't know if changes which I do by this way will
survive restarting
original driver.

Even if I have to write some data into NIC's memory? It sounds impossible
.... It's the
point I want to do ... flush some data into NIC.

If you set them into registry keys driver read from on start that will work

Usually on start miniport driver set firmware with
NdisMapFile() , so if that not reset data you wrote that OK otherwise you
can't .

Anyway - after unloading, yes, the driver will be loaded again and
will do it's initialization.

Is it possible to somehow suspend miniport driver for some time? I want to
temporary upload my own NDIS miniport, do somethig and then let original
driver run. But I'd like to avoid original driver re-initialization.
Thank's for answers

Nope. You better off working with the NIC vendor to solve your problem.
