8.15 SMI#/OVT# Property Select -- Index 4Ch (Bank 0)
Reset Condition: Resume Reset.
Register 4Ch selects SMI modes, OVT modes, OVT sources and OVT polarity.
If OVT_MD selects ACPI mode, register 5Eh determines the temperature interval between each OVT
is issued. Default sets to 5, that is, every time temperature reaches 5*n degree, an OVT will be issued.

mode with hysteresis type. Temperature exceeding T
(Over-temperature, defined in Bank 1/2) causes an
