Intel SDS2 manual Firmware BMC

Intel® Server Board SDS2 BIOS

6.2.3.3Memory Bus Error

The BMC monitors and logs memory errors. The BIOS will configure the hardware to notify the BMC on correctable and uncorrectable memory errors. Uncorrectable errors generate an SMI to stop the system and prevent propagation of the error. The BMC will query the hardware for error information when notified.

6.2.3.4System Limit Error

The BMC monitors system operational limits. It manages the A/D converter, defining voltage and temperature limits as well as fan sensors and chassis intrusion. Any sensor values outside of specified limits are handled by the BMC and there is no need to generate an SMI to the host processor.

6.2.3.5Processor Failure

The BIOS detects processor BIST failure and logs this event. The first OEM data byte field in the log can identify the failed processor. For example, if processor 0 fails, the first OEM data byte is 0. The BIOS depends upon BMC to log the watchdog timer reset event.

6.2.3.6Boot Event

The BIOS downloads the system date and time to the BMC during POST and logs a boot event. This does not indicate an error, and software that parses the event log should treat it as such.

6.2.3.7Chipset Failure

The BIOS detects the chipset (CNB2.0HE-SL and CIOB20) failure and logs this event. The chipset error generates an SMI.

6.2.4Firmware (BMC)

The BMC implements the logical System Event Log (SEL) device as specified in the Intelligent Platform Management Interface Specification, Version 1.5. The SEL is accessible via all BMC transports. This allows the System Event Log information to be accessed while the system is down via out-of-band interfaces.

6.2.4.1Sensor Number and Types Codes

The BIOS generates a POST error message when the System Event Log is full. This warning will not inhibit the system from booting if halt on Post Error code is disabled in the BIOS Setup in the Advanced menu.

Sensor Name, Sensor number and Sensor type for the SDS2 platform are listed in the following Table 24 Platform SEL Log Sensors for SDS2.
