Microsoft Windows generic hardware abstraction layers (HAL) for Intel architectures (Halx86.dll, Halapic.dll, Halmps.dll, and Halia64.dll) support the Machine Check Architectures (MCA) for the Intel Pentium Pro and Itanium processors. The HAL enables Machine Check Exception (MCE) reporting for all implementation-defined errors.

For more information about the MCA-specific interface for drivers for Intel Pentium Pro and Itanium processors, see MCA Interface for Drivers.

Note Windows Vista and later versions of Windows do not support the type of Machine Check Architecture (MCA) and Machine Check Exception (MCE) reporting that is described in this topic. MCA and MCE reporting are supported through Windows Hardware Error Architecture (WHEA) instead.
