SCSIPORT driver question

NTDEV
1

Hi,
I’m trying to write SCSIPort Upper filter( SCSI bus PDO upper filter, if
I’m right in terminology) in Win2K. I found that scsiport.sys is target
driver for my filter. The problem is that I didn’t find any information
about scsiport driver in registry. Additionally I tried to find in SoftIce
in driver/device list something with such name but didn’t find. How can I
connect my filter to this driver, if I don’t know it’s
devicename(IoAttachDevice) or it’s device object
pointer(IoAttachDeviceByPointer)?
Where can I find additiononal information about such type of filters?

Thanks, Max

A bus filter driver is a dual-role pnp driver that is:

  1. a ‘normal’ FDO upper-filter driver for scsi bus drivers;
  2. a PDO filter driver for the PDOs created by the FDOs filtered under
    (1).

For scsi the bus driver device class guid is GUID_DEVCLASS_SCSIADAPTER.
Use SetupDiOpenClassRegKey on this guid to access the registry key, add
your driver as an UpperFilter, and reboot the system.

Register it as “LowerFilter” for “SCSI” device class.
