Subject: Please teach me X86 I/O port 0x61 

Dear all.

I investigate about  NMI kernel messages.
Linux kernel read 0x61 address using inb(61h).

I search a amd opteron cpu following manuals.
but I do not find  explanation of 0x61 address.

http://support.amd.com/us/psearch/Pages/psearch.aspx?type=2.1&product=2.1.4&contentType=Tech+Doc+Processor&ostype=&keywords=&items=20

Could you teach me a 0x61 address of X86 arch >

Best regards.
