The AMD-K6-IIIE+ processor does not support the generation
of a machine check exception. However, the processor does
provide a 64-bit machine check address register (MCAR), a
64-bit machine check type register (MCTR), and a machine
check enable (MCE) bit in CR4.
Because the processor does not support machine check
exceptions, the contents of the MCAR and MCTR are only
affected by the WRMSR instruction and by RESET being
sampled asserted (where all bits in each register are reset to 0).
The formats for the machine-check address register and the
machine-check type register are shown in Figure 30 and Figure
31, respectively. The MCAR register is MSR 00h, and the MCTR
register is MSR 01h.
