5.1.1Fault Resilient Booting

The Sahalee BMC implements Fault Resilient Booting (FRB) levels 1, 2, and 3. If the default bootstrap processor (BSP) fails to complete the boot process, FRB attempts to boot using an alternate processor.

•FRB level 1 is for recovery from a BIST failure detected during POST. This FRB recovery is fully handled by BIOS code.

•FRB level 2 is for recovery from a watchdog timeout during POST. The watchdog timer for FRB level 2 detection is implemented in the Sahalee BMC.

•FRB level 3 is for recovery from a watchdog timeout on hard reset or power-up. The Sahalee BMC provides hardware functionality for this level of FRB.

5.1.1.1FRB-1

In a multiprocessor system, the BIOS registers the application processors in the MP table and the ACPI tables. When started by the BSP, if an AP fails to complete initialization within a certain time, it is assumed nonfunctional. If the BIOS detects that an application processor has failed BIST or is nonfunctional, it requests the BMC to disable that processor. The BMC then generates a system reset while disabling the processor; the BIOS will not see the bad processor in the next boot cycle. The failing AP is not listed in the MP table (refer to the Multi-Processor Specification, Rev. 1.4), nor in the ACPI APIC tables, and is invisible to the operating system. If the BIOS detects that the BSP has failed BIST, it sends a request to the BMC to disable the present processor. If there is no alternate processor available, the BMC beeps the speaker and halts the system. If BMC can find another processor, BSP ownership is transferred to that processor via a system reset.

5.1.1.2FRB-2

The second watchdog timer (FRB-2) in the BMC is set for approximately 6 minutes by BIOS and is designed to guarantee that the system completes BIOS POST. The FRB-2 timer is enabled before the FRB-3 timer is disabled to prevent any “unprotected” window of time.
