MSR(Model-Specific Register) Additional, indirectly-accessible, registers containing control or status information about various aspects of the processor such as caches, performance counters, and the like.	These registers, accessible via the RDMSR and WRMSR instructions, were added with the Pentium and later-model 486 processors. 00000000h - Pentium, Pentium Pro - MACHINE CHECK EXCEPTION ADDRESS
Size:	32-36 bits
Access:	Read
Desc:	on any Machine Check exception (INT 12), this MSR(Model-Specific Register) Additional, indirectly-accessible, registers containing control or status information about various aspects of the processor such as caches, performance counters, and the like.	These registers, accessible via the RDMSR and WRMSR instructions, were added with the Pentium and later-model 486 processors. contains the physical
	  address at which the exception occurred
Notes:	also supported by AMD Am5k86, K5, and K6; however, the K6 does not
	  actually support the machine check -- this register may be written
	  on the K6 to emulate that functionality
	this register does not exist on the Pentium Pro/Pentium II, but will
	  not cause an exception when accessed
