Intel Application Accellerator and byte order

I made an application that involves sending SCSI commands to a peripheral
device via the SPTI (Scsi Pass-Through interface). I made a routine that
automatically fills in the SPTI structure then sends it with DevIO. I
developed it on my system which has the Intel Application Accellerator
installed. It never occurred to me that this would be a problem but it has
turned out to be one. The app has worked perfectly until I recently had an
occasion to uninstall the IAA and it broke it. Some commands get through
and seem to work but many other do not.

Does anyone know if the IAA fiddles with byte order or alignment in a way
that the default Windows drivers do not ? Where should I start looking for
the problem in my app ?

IAA has a couple of filters in the storage stack, are you sure you got both
of them otherwise you would have problems.

You're talking about filters not removed by the IAA uninstall ?
How would I identify them ?

thanks,

Got it now. All is well. Thanks for the heads up.

This is what comes of blindly trusting software written by major
manufacturers. I had assumed the IAA uninstaller had
completely removed it. When I checked Device Manager/IDE ATA Controlers
I saw the IAA was still there. It took 2 reboots to get rid of it.
Now my app is back working as it should.
