I really need to convince win7 to load the checked ndis.sys. Is there any hope that the ‘debug’ boot loader in win7 actually works with windbg and will load boot load drivers?
Did someone say that it would?

One can only hope. What I was asking is ‘has anyone gotten this to work, or at least tried and failed?’
The last time this came up, Doron admitted that it was borked in vista but held out hope for win7.
Negative. I had just assumed that this is going to be broken indefinitely.
I’d love to be wrong.

Have you tried just doing the, “change the ImagePath to
\system32\drivers\chk\foo.sys” trick? Usually works quite nicely.

I’m guessing that neither of you have actually tried that with ndis on win7.
The answer is yes, I’ve tried it, and it bugchecks in NETIO.SYS. Ndis is a port driver and a kernel dll. I’m not convinced having an explicit load of ‘ndischk.sys’ while ndis.sys is hanging out in system32\drivers actually works. It is also possible that the checked ndis.sys requires checked netXXXX.sys components as well, which would be equally horrendous.
bcdedit /set bootdebug on
Now .kdfiles will work within the boot loader.

Now that is good news.
Thanks, Jake.

Thanks Jake.

How’d you guess that?
Then just replace ndis.sys itself and see if that works (or use .kdfiles
apparently, good to hear boot time replacement is fixed).

I believe this will work for win7 (although I can’t triple check that I am not misremembering from here).
For boot start drivers, you’d need to enable bootdebug iirc.
The usual requirements re: matching the whole filename still apply.

Scott you cannot ‘just replace ndis.sys’ on win7. Well maybe you can. Again - have you tried this?
Yes, that works.
On Windows 7 you can take ownership of system files (some mojo on the
properties page). Then rename the ndis free-build driver (for later
restoration) and copy the ndis checked-build to the drivers folder. No “SFP”
on W7.
I don’t recall any need to have other checked components.
I like the ImagePath solution better.

I’ve done most wrappers, though not NDIS specifically. I suppose it could be
magically ju-jued and locked down, though the usual trick of taking
ownership and diddling the ACL allowed me to delete it without a problem.

Well thanks Scott - that last bit actually worked. What a waste of an afternoon. Of course the whole point of this effort was to get ndiskd to work, but actually that doesn’t work either, even with the checked ndis and the public checked os ndis symbols. What a pile of frustratingly stupid barriers.
FYI if there is some trick to convincing win7 to start with bootdebug actually enabled such that windbg connects, I have no idea what that would be either. Not that it matters anymore.
Color Coded Frustration Level: ORANGE.
Sorry for any snidery. I’m pissed at tools and lashing out randomly.
bcdedit /set testsigning on
takeown /f ndis.sys
icacls ndis.sys /grant HOLLISTECH\markr:(F)

Yes that works - but of course ndiskd doesn’t work outside of redmond. Yet another bork’d debugger extension.
Thanks for all the help, I’m back to grovelling through the disassembler looking for clues.
We are working on a fixed ndiskd. Does not help you today, but hopefully some time soon…

NDISKD is hopelessly broken and ‘they’ know about it. Another case of the
tools getting ‘wicked smaaatt’ but nobody realizing that the smarts rely on
symbols that are stripped from the public PDBs.
It has been that way for a long time now. Too bad, NDISKD is actually
useful (well, was actually useful).
Only orange, huh? I would count that as a good day.
