How to change driver verifier list on the fly? (Using debugger)

NTDEV

Hi All,

Is it exists any way to turn off driver-verification using WinDBG/KD capabilities/or manually on the
fly at the kd debugger session? Even before the boot has been completed. (Because otherwise I’m
unable to replace my NDIS packet-driver because I got nice bug-check dump at my checked Win2K/SP2
just before network has been loaded and available for my needs)
AFAIK ‘!verifier’ extension provide the way to see current settings. But I need to change them…

–
Thanks in advance,
Timur Safin

Go into Safe mode and run “verifer /reset”?

Hi Doug,

Thanks for you help. It’s THAT simple!

[I followed the harder way: selected the stop at the initial breakpoint at WinDBG, rebooted, at the first stop saved the hardware breakpoint on “nt!iopVerifierOn”, continued, once it has been changed to 1, I returned it back to 0, continued and end up with the same error at my driver, even without the verifier IRQL checking. Oh-ho. Going to fix it someway…]

But yours way is better :slight_smile:

Thanks,
Timur
