Hi Folks,

I'm trying to find things out on my end.  I don't have any hardware to test things, and would like to have a volunteer for trying things out.

Can someone at Microsoft confirm that StorPort driver in SP2 indeed
ignores a miniport's attempt to increase the NumberOfPhysicalBreaks
above 17?

We are running WinOF SRP with SP2 and are trying to get buffer sizes
above 64K bytes, and it is just not happening. We cannot switch back to
SP1.

If this is simply not doable in SP2 with a Storport Miniport, we would
sure like to know, so we can drop this and move on.

Fab, can you possibly get a confirmation on this????

Thanks.
Usha

> Seems like MS patched the StorPort in SP2.

SP2 has an updated storport driver. There is also a post SP2 update to
the storport driver (from about April/May 2007), available from I
believe the Microsoft support website. My unconfirmed guess is we may
eventually see an updated W2K3 storport with some of the W2K8 changes.

There are changes in both the SP2 and post-SP2 storport that can affect
storage miniport drivers, like the SRP driver.
