Intel® Server Board SE7501WV2 TPS

BIOS

Sensors are managed by the BMC. The BMC is capable of receiving event messages from individual sensors and logging system events. Refer to the SE7501WV2 BMC EPS for additional information concerning BMC functions.

6.32 SMI Handler

The SMI handler is used to handle and log system level events that are not visible to the server management firmware. If the SMI handler control bit is disabled in Setup, SMI signals are not generated on system errors. If enabled, the SMI handler preprocesses all system errors, even those that are normally considered to generate an NMI. The SMI handler sends a command to the BMC to log the event and provides the data to be logged. System events that are handled by the BIOS generate a SMI.

6.33 PCI Bus Error

The PCI bus defines two error pins, PERR# for reporting parity errors, and SERR# for reporting system errors. The BIOS can be instructed to enable or disable reporting PERR# and SERR# through NMI. For a PERR#, the PCI bus master has the option to retry the offending transaction, or to report it using SERR#. All other PCI-related errors are reported by SERR#. SERR# is routed to NMI if bit 2 of I/O register 61 is set to 0. If SERR# is enabled in BIOS setup, all PCI-to-PCI bridges will generate an SERR# on the primary interface whenever an SERR# occurs on the secondary side of the bus. The same is true for PERR#s.

6.34 Processor Bus Error

If irrecoverable errors are encountered on the host processor bus, proper execution of the BIOS SMI handler cannot be guaranteed. The BIOS SMI handler will record errors to the system event log only if the system has not experienced a catastrophic failure that compromises the integrity of the SMI handler.

6.35 Single-Bit ECC Error Throttling Prevention

The system detects, corrects, and logs correctable errors as long as these errors occur infrequently (the system should continue to operate without a problem).

Occasionally, correctable errors are caused by a persistent failure of a single component. Although these errors are correctable, continual calls to the error logger can throttle the system, preventing further useful work.

For this reason, the system counts certain types of correctable errors and disables reporting if errors occur too frequently. Error correction remains enabled but calls to the error handler are disabled. This allows the system to continue running, despite a persistent correctable failure.

The BIOS adds an entry to the event log to indicate that logging for that type of error has been disabled. This entry indicates a serious hardware problem that must be repaired at the earliest possible time.

The system BIOS implements this feature for correctable bus errors. If ten errors occur within an hour, the corresponding error handler disables further reporting of that type of error. The BIOS re-enables logging and SMIs the next time the system is rebooted.
