Microsoft Windows generic hardware abstraction layers (HAL) for Intel architectures (Halx86.dll, Halapic.dll, Halmps.dll, 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.
