That is a significant progress.

I did make changes to ndiscvt and I improved a few checks,
but I am not aware of any regression.

These missing symbols are functions provided by Windows
and needed by the driver, but which are not emulated by ndis.
I have not enough knowledge to emulate the WMI ones.

These missing ones are easier to emulate, though I am not
sure whether reading a file is allowed within an OpenIndiana
driver. The required file may have to be linked to the driver
at the building stage.

Can you please where I can get this driver from, so that
I can try myself ?

I know this too well : I have three computers.
On the first one, OpenIndiana cannot boot (some problem related
to the BIOS),
on the second one, OpenIndiana cannot access the internal drive,
on the third one, I had no network access until recently.

And no much hope for improvements...
