UpperFilter to SBP2PORT.SYS

Dear Developers,

I want to install an UpperFilter to SBP2PORT.SYS.
How do I install it ? What registry entries are required to accomplish it ?

Thanks and regards,

Hi,

To install a filter driver on an already installed driver, follow these
steps :

• First write a filter driver INF file (with no reference to the driver to
  filter);
• Then, write an install application which use SetupAPI to install your INF
  file.

Join to this Email, you will find the code of my INF file and the source
code of my installer:

NB.: - My filter driver’s name is ‘SlFilter.sys’, and the GUID of the
driver I want to filter
is {6BDD1FC1-810F-11D0-BEC7-08002BE2092F} (1394 Bus).

• To install my inf file on Win98, I use this syntax:
  InstallFilter SlFilter.inf SlFilterW98
  {6BDD1FC1-810F-11D0-BEC7-08002BE2092F}
• To install my inf file on Win2K, I use this syntax:
  InstallFilter SlFilter.inf SlFilterW2K
  {6BDD1FC1-810F-11D0-BEC7-08002BE2092F}

Hope this helps,

Regards.
