Intel® Server System S7000FC4UR TPS BMC Functional Specifications
Revision 1.0
257
22.3.4 Soft Reset and Hard Reset
The BMC monitors an ICH6 signal called BIOS_POST_CMPLT_N, which deasserts at the
beginning of POST and asserts at the end of POST. The signal deassertion indicates that a
system reset has occurred. The BMC monitors this signal to detect both hard resets and soft
resets. The BIOS converts all INITs into hard resets. Therefore, INITs also result in the BMC
sensing a system reset.
The BMC detects these resets but does not participate in the reset mechanism.
22.3.5 BMC Command to Cause System Reset
Chassis Control is the primary command used to reset the system. The Set Processor State
command, which is used by the BIOS during POST, can also cause a system reset.
22.3.6 Watchdog Timer Expiration
The watchdog timer can be configured to cause a system reset when the timer expires. See the
Intelligent Platform Management Interface Specification, Version 2.0.
22.4 BMC Reset Control
22.4.1 BMC Exits Firmware Update Mode
The BMC firmware can be updated using firmware transfer commands through the LPC
interface. The BMC enters firmware transfer mode if it detects that the Force Update signal is
asserted during initialization or if the operation code checksum validation fails. When exiting
firmware transfer mode, the BMC resets. The BMC re-synchronizes to the state of the processor
and power control signals it finds when it initializes.
22.4.2 Standby Power Comes Up
The system has AC power applied, but the system is not up. The BMC resets the system when
DC power output from the power supplies is available. The BMC re-synchronizes to the state of
the processor and power control signals it finds when it initializes.
22.5 System Initialization
The following items are initialized by both the BIOS and the BMC during system initialization.
22.5.1 Processor TControl Setting
Processors used with this system implement a feature called Tcontrol, which provides a
processor-specific value that can be used to adjust the fan control behavior to achieve optimum
cooling and acoustics. The BMC cannot access these values. The BIOS reads the values
during POST and communicates them to the BMC using the Set Processor Tcontrol command.
The BMC uses these values as part of the fan speed control algorithm.
