Question about StorPort miniport for boot drive

Hello Gurus,

Is a filter driver for a storport allowed for an HBA which is connected
to boot LUN? Any insight would be very helpful.

Regards,

A filter should work in this scenario. The filtering architecture in the pnp manager is entirely generic, it does not know an HBA from an oscilloscope.

You want to filter the HBA fdo stack or the storage device LUN stacks?

Filter devices work fine on boot devices, although may be a problem for text
mode setup on pre-VIsta as there is no syntax in txtsetup.oem to add a
filter driver. This means you would need to run the initial phases of OS
setup withough the filter, or else only work on Vista and later. Or, you
can’t do text mode setup, which I believe would prevent you from getting
pre-VIsta WHQL certification.

I wanted to filter the HBA fdo stack. Looks like it is going to pose a
problem as I require driver for 2003 as well.

Thanks for the answer. I appreciate it.
