SYMPTOMS

A SCSI miniport driver might not receive SRB_FUNCTION_SHUTDOWN, which is used to indicate that Windows 95 is shutting down.

CAUSE

Under specific circumstances, Configuration Manager removes the SCSI miniport driver before IOS can notify SCSIPORT to issue SRB_FUNCTION_SHUTDOWN to the SCSI miniport driver. This occurs if BOTH of the following are true:

The driver has no logical boot configuration (that is, it was not active before Windows 95 switched to protected mode).
The driver's ConfigFlags hardware registry value has the following bit clear: CONFIGFLAG_NOREMOVEEXIT

RESOLUTION

Set the CONFIGFLAG_NOREMOVEEXIT bit flag (this flag value is defined in regstr.h). The following text, when included in your .inf file, will accomplish this:

   [drivername.hw]
   AddReg=driverhw

   [driverhw]
   HKR,,ConfigFlags,1,00,02,00,00

Implementing this will allow the miniport driver to see SRB_FUNCTION_SHUTDOWN.

STATUS

This behavior is by design.
