Abstract:
A boot recovery system includes a serial peripheral interface (SPI) storage that stores a primary boot block. A primary SPI controller is connected to the SPI storage through a primary SPI bus. An embedded controller (EC) includes an EC storage that stores a recovery boot block. The EC is coupled to the primary SPI bus through a secondary SPI bus. The EC is configured to determine that the primary boot block should be replaced, retrieve the recovery boot block from the EC storage, replace the primary boot block in the SPI storage with the recovery boot block through the secondary SPI bus, and initiate an information handling system (IHS) reboot process. The determining, retrieving, replacing, and initiating may be performed by the EC while a processing system that is coupled to the primary SPI controller is not in an operating mode.
