The actualtemperature control value is the TControl value plus the temperaturefield. Reserved bits should be set to 0.Table 92. Boost value Sub-recordByteBoost value sub recordName0 Sub-record type Value must be 0xFFDescription1 Fan failure boost value This is the PWM value (% value – 0-100) to use if a fan failure or fanremoval has occurred.2 Temperature threshold boostvalue3 Reserved 1 Value should be 04 Reserved 2 Value should be 0This is the PWM value (% value – 0-100) to use if critical temperatureor chassis top cover removal has been detected.Table 93 Sensor failure exclusion Sub-recordByteSensor failuresub recordName0 Sub-record type Value must be 0xFD1 Sensor count (N) Number of sensors to follow2-NSensor numberDescriptionThis sensor number will not contribute to system fan boost if a failureor threshold crossing occurs.170Intel ConfidentialRevision 1.1
