: Different hardware implementations may handle MCEs differently, making it challenging to develop a uniform handling strategy.

On legacy 32-bit systems, an MCE often resulted in a triple fault (reset). On x64 with Windows and Linux, the OS attempts to log the MCA banks (registers like IA32_MCG_STATUS and IA32_MCI_ADDR ) before panic-ing. On x64 with Windows and Linux, the OS

In the x64 architecture, exception type 0x12 represents the Machine Check Exception link. This link is used to connect the MCE handler to the processor's error handling mechanism. When an MCE occurs, the processor uses the exception type 0x12 to identify the error condition and transfer control to the MCE handler.
