@@ -86,15 +86,19 @@ limits. The chip supports only a single register to configure the hysteresis,
 which applies to all limits. This register can be written by writing into
 temp1_crit_hyst. Other hysteresis attributes are read-only.
 
+If the BIOS has configured the sensor for automatic temperature management, it
+is likely that it has locked the registers, i.e., that the temperature limits
+cannot be changed.
