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/Power-up. The Sahalee BMC provides hardware functionality for this level of FRB.
