I would like to completely disable the verifier program, but so far I can't. I am trying to install an old video driver. This is causing constant BSOD errors - all showing "Driver Verifier IOManger Violation" While some laptops will work without this needing to be done, there is no way to tell this without testing the laptop with a system.I am trying to disable the Windows 10 driver signature verifier. The best way to check if a laptop would be compatible is to check the ability to disable Intel VT-d or AMD-Vi in the BIOS. It's not something that is easily checked ahead of time. The attribute settings are a design decision that is normally based on the intended use of various PCI ports but could easily be an oversight as this new capability is rolled out. Laptop manufacturers/vendors determine which PCI segments DMA protection is applied to by setting specific attributes in the AHCI information that Windows gathers when booting the system. If updating Windows is not an option, please make sure the end-user is aware of the risk. As such, keeping the computer in a secured environment will reduce the risk of an attack.Īs the previous workaround left the end-user vulnerable to a cyberattack, it is advisable to first update Windows to include service pack KB5014032 or pursue all other lines of troubleshooting first.
The attack which the Kernel DMA Protection prevents requires the attacker to have hands-on access with the computer. Additional InformationThis Blue Screen occurs due to the interaction between the data transmitted from the PXIe controller to the connected PC and the Kernel DMA (Direct Memory Access) Protection added in Windows 10 Version 1803.
