AGP_ILLEGALLY_REPROGRAMMED

Unauthorized AGP hardware reprogramming for AGP_ILLEGALLY_REPROGRAMMED

AGP_ILLEGALLY_REPROGRAMMED is bug check code 0x00000106.

This bug check indicates that Windows detected AGP hardware configuration being changed outside the expected graphics/chipset ownership path. It is a platform/driver integrity issue in the legacy AGP stack.

How to read it in a dump

  • The suspect component can be a chipset driver, display miniport, firmware path, or low-level utility touching registers.
  • The question is who changed AGP configuration and whether that change races the graphics stack.
  • It is not a normal display mode-set error.

What to check

  • Review low-level graphics/chipset utilities, unsigned drivers, overclocking tools, and firmware updates.
  • Check whether the system is old AGP hardware, a VM, or an emulator presenting AGP-like state.
  • Use a full dump to inspect the graphics and bus-driver stack.
