Intel® Server Board SDS2 BIOS

Revision 1.2

Order Number: A85874-002

6.2.3.3 Memory 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.

6.2.3.4 System 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.

6.2.3.5 Processor 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.

6.2.3.6 Boot 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.

6.2.3.7 Chipset Failure

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

chipset error generates an SMI.

6.2.4 Firmware (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.

6.2.4.1 Sensor 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.
