73 (Intelligent Platform Management Interface) is a standard for
74 monitoring system hardware by permitting generic code to detect

97 The motherboard's BMC must support the chassis device and the optional
98 power cycle subcomand of the chassis control command as described in section 28.3
100 The length of time the system is off will be at least one second, but
101 may be longer if the power cycle interval has been set (see section 28.9).
