I'm running Windows Server 2008 R2 x64 and I have a driver that isn't signed so the Device Manager displays the following message:
"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"
I know that I can disable driver signing enforcement per-boot by using F8 but I'd like something more permanent, or I'd like a way to sign this driver myself and allow Windows to accept it.
Microsoft has some information on Signing Drivers during Development and Test (Windows Vista and Later). Self-signing the driver would be preferred to disabling signature verification globally.
I had to upgrade an N54L BCM,
Driver Signature Enforcement Overrider 1.3b
