Problem Regarding SCSI Miniport...

NTDEV
1

Hi All,

I am working with the SCSI Miniport Driver as a virtual driver, where i am
giving it’s Interfacetype in the Hw_Initialization_Data structure as a ISA
& also assigned some ports for that.It works fine,but i am facing problem
with multiple restarts.Even with the very first installation also it asks
for restart & if i try to Enable/Disable the Driver then also it asks for
restart.When i keep a break point to the HwScsiAdapterControl & try to
Disable/Enable the driver it never goes to that routine at all.would there
any problem while specifying the Interface Type?

Any Suggestions or ideas?

Thanks & Regards,
Vishwanath M.

You do not use HwScsiAdapterControl unless you have a WDM SCSI mini-port.
You didn’t specify what OS.

Hi Gary,

Actually I am working with the Windows-2000 Driver Development & could you
please explain me more on what u are saying? Why shouldn’t I use the
HwScsiAdapterControl?

Thanks & Regards,
Vishwanath M.

HwScsiAdapterControl is part of the WDM extension for a WDM SCSI mini-port.
If your a writing a legacy miniport, and since you mentioned ISA I did
indeed assume you were dealing with a legacy miniport. A WDM minip[ort is
designated by specifying the proper size and setting the AdapterControl
callback function. If the size is specified as a legacy driver, then yopur
structure may be legal, but AdapterControl will not be called since it does
not exist for a legacy driver.

Hi Gary,

Thanks for u’r reply.
Actually we wanted it to be only ISA as the interface type & also we
made the PNP interface in the Registry using Inf file.But still it just
comes to the HwScsiAdapterControl only once & that too he will try to
enumerate all the possible states from the Array.But when I am trying to
either Disable/Enable the driver it never calls the AdapterControl
function?So what could be the problem?
Is n’t it possible for making it work without restart of the system by
giving the interface type as Isa?
