Miniport driver

Hi,
I have one doubt which I would to clear.
How can we attach upper filter driver to a miniport
driver in Win2k.
For example,
Miniport driver creates FDO for the controller.
I would like to place my filter driver in such a way
that it receives FDO created by the miniport as a PDO
in its AddDevice() routine.

Thanks in Advance,
Regards,
Gurpreet

It looks like this is not documented… You can try to write a SCSI filter
driver (see samples in DDK) and attach to devices on “per class” basis, not
on “per miniport/port” one. And you can filter requests in your filter
driver and process only the ones that have port ID that belongs to the
miniport you’re initerested at.

Thanks,
I have already tried doing that way long time back.
My requirements are forcing me to attach per
“miniport/port” basis.
Actually I want to create a virtual disk in my filter
driver but class driver is not sending a call like
IRP_MN_QUERY_ID,etc to my virtual disk in the filter
driver.
Well God bless me!!!

What miniport? SCSI? Or NDIS?

Hi,

I’ve tried this some time ago (making virtual hardware be attached to real
SCSI controller). I do not think it will work. Who will create device PDOs
for you?

Anton
