Also, if you’re looking for information to get started using windbg, there’s
a tutorial in the root of your windbg installation -
‘kernel_debugging_tutorial.doc.’

Good luck,

Pretty much. Also, you might want to run your driver through PreFAST (see
the wdk docs) and then under driver verifier.

I know that this doesn’t seem like much help, but unfortunately, there is no
easy (or other) way to get started with this stuff.

Good luck,

mm

Crankup WinDbg, install a checked build of the drivers and start stepping
through the source.

Hello all,

I’m a software developer for a small company that makes PCI video
components. We have recently been moving towards more software-centered
products, and the original authors of our device drivers are no longer
around. We still need some of our old cards to be Windows 7-compatible, and
that is where my problem lies.

One of our cards in particular, once installed, will cause the OS to hang
during boot (when it gets to the “pulsing” windows logo). Strangely enough,
when the device is disabled in device manager (done in safe mode) the system
starts right up; if I then re-enable the device, it works. Then when I
restart, it will hang again (sometimes shutdown will hang as well).
I’ve traced through the boot log and it says the driver in question is in
fact loading–it is a dozen or so drivers further down the list where the
hang seems to be happening.

As you can imagine, I am a little out of my depth here; if anyone has any
suggestions or advice as to how to proceed, I would be eternally grateful.

Cheers,
Kevin

What are these “video components” - it isn’t the “main” video adapter of
the machine?
Maybe a capture card or a camera control?
